PREFACE
Central Water Commission had started Flood Forecasting & Warning services in
India in November, 1958 by setting up one forecasting station at Old Delhi Bridge, for
the national capital, on the river Yamuna. Its network of Flood Forecasting and Warning
Stations gradually extended throughout the country covering almost all the major inter-
state flood prone river basins.
During 2020, the flood forecasting services are expanded to 328 stations which
comprised of 198 level and 130 inflow forecast stations in 20 major river basins. It
covered 22 States besides Union Territories of NCT Delhi, Jammu & Kashmir and
Daman & Diu. The flood forecasting activities of the Commission are being performed
every year from May to December through its 29 field Divisions which issue flood
forecasts and warnings to the civil authorities of the states as well as to other
organizations of the Central & State Governments, as and when the river water level
touches or is expected to cross the warning level at the level flood forecasting stations.
During Flood Season 2020, level forecasts were issued for 129 stations out of 198
stations and inflow forecasts were issued for 88 reservoir/ dam/barrages out of 130
inflow stations. The inflow forecasts are formulated whenever the inflow into the
reservoirs exceeds the threshold value fixed by the respective project authorities for
reservoir regulation as well as flood moderation.
During the year 2020 flood season,7 Flood Forecast stations flowed in Extreme
Flood situation. Severe Flood situation was witnessed in 88 Flood Forecasting Stations
and 34 Flood forecast stations witnessed Above Normal Flood Situation. The major
flood events this year was the Extreme Floods witnessed in Assam ,Bihar, Chattisgarh,
Uttar Pradesh, Uttarakhand, Madhya Pradesh, Maharashtra, Odisha, Andhra Pradesh,
Tamilnadu, Telangana and Karnataka state.
During the year 2020, 11721 forecasts were issued out of which 11198 forecasts
(95.54%) were found to be within the limits of accuracy. The number of level forecasts
issued during the year 2020 were 8243 out of which 8133 (98.67%) was within the limit
of accuracy of ± 0.15 m. The number of inflow forecasts issued were 3478 out of which
3065 (88.13%) was within limits of accuracy of ±20%. Daily Flood Situation Reports
cum Advisories (DFSITREPcA) based on 5-day rainfall warning of IMD were issued on
daily basis. Advisories about Extreme floods in Assam, Bihar, Chattisgarh, Uttar
Pradesh, Uttarakhand, Madhya Pradesh, Maharashtra, Odisha, Andhra Pradesh,
Tamilnadu, Telangana and Karnataka were issued in DFSITREPcA for taking up relief
and rescue operations in advance which were well appreciated by the beneficiaries at
both National and State Levels.
i
Rainfall-Runoff advisories based on the satellite estimates of rainfall, AWS/ARG
data of IMD/CWC as well as the rainfall forecast products of Weather Research and
Forecast (WRF) model at a resolution of 0.25mx0.25m was continued in 2020 flood
season and was put in Uniform Resource Locator(URL)http://120.57.32.251/. CWC
wishes to place its acknowledgements for the services provided by IMD through its
Hydromel & Numerical Weather Prediction and AWS Lab units in the Headquarters, Pune
as well as various FMOs of IMD.
The level of performance achieved, has been possible as a result of the dedicated
team work of the officers and staff manning the various activities of hydro-
meteorological observations & flood forecasting and monitoring of the field offices.
Flood Forecast Monitoring (FFM) Directorate plays an important role in compiling

the information received from various field offices at Headquarters and issues daily
bulletins which are sent to all stakeholders. I wish to place on record my deep
appreciations of the efforts put in by the officers and staff of FFM, FCA - 1 and FCA - 2
Directorates in carrying out the flood forecasting work with utmost devotion &
dedication. The staff of FFM Directorate, along with other supporting staff from other
Directorates/Wings during flood duties in the flood season of 2020 also deserves all
appreciation in keeping the control room fully functional on all the weekdays, including
holidays, Saturdays & Sundays. The control room was kept operational round the clock
throughout the flood season.
It is hoped that the momentum gained in expanding the flood forecasting

network, improving performance of the forecast and adopting various modernization
including in the field of dissemination techniques will be further accelerated to achieve
greater effectiveness of each and every forecast with the help of mathematical
modelling supported by real-time data from telemetry.
Suggestions/ comments of the users of this report with a view to further enhance
its usefulness are welcomed and will be in corporate in the next edition.

EXECUTIVE SUMMARY
0.1 METEOROLOGICAL SITUATION
During 2020, the southwest monsoon performance was as given below.
The seasonal (June - September) rainfall over the country as a whole was 109% of its
Long Period Average (LPA) in 2020. It was the third highest after 112% of LPA in 1994
and 110 % of LPA in 2019.
 Seasonal rainfalls over Northwest India, Central India, South Peninsula and East &
Northeast (E & NE) India were 86%, 115%, 129% and 107% of their respective LPA.
 Out of 36 meteorological subdivisions, 2 subdivisions (5% of the total area of the
country) received large excess rainfall, 13 subdivisions (35% of the total area of the
country) received excess rainfall, 16 subdivisions (45% of the total area of the
country) received normal seasonal rainfall and 5 subdivisions (15% of the total area
of the country) received deficient season rainfall during the season.
 Monthly rainfall over the country as a whole was 117% of LPA in June, 90% of LPA
in July, 127% of LPA in August, and 105% of LPA in September.
 Southwest monsoon current reached south Andaman Sea and Nicobar Islands on
17th May, 2020 (5 days ahead of its normal date), but further advance was sluggish.
It set in over Kerala on 1st June coinciding with its normal date for onset over Kerala;
Monsoon covered the entire country on 26th June, 2020; 12 days before its normal
date (8th July).
 Monsoon started withdrawing from western parts of northwest India on 28 th
September, 2020 against the normal date of 17th September, 2020 with a delay of
around 11 days. The Southwest Monsoon withdrew from the entire country on 28 th
October, 2020.
 During the season, one Severe Cyclonic Storm “NISARGA” formed during 1 st to 4th
June. This year also witnessed absence of monsoon depression during the season.
 The forecast for monsoon onset over Kerala for this year was correct, which is the
fifteenth consecutive correct forecast for the event (except for the year 2015) since
issuing of forecast for the onset over Kerala started in 2005. The Forecasted date of
onset of monsoon over Kerala was 5th June with a model error of ±4 days and
realized date of onset of monsoon over Kerala was 1st June in this year.
 The forecasts for the rainfall over the country as a whole during the season,
forecasts for the seasonal rainfall over three broad homogeneous geographical
regions (Central India, Northeast India and South Peninsula) and forecast for August
rainfall and for rainfall of second half of the monsoon season for the country as a
whole were found to be underestimated with respect to the actual rainfall whereas
the forecasts for the rainfall for the country as a whole during July and forecast for
the seasonal rainfall for Northwest India were found to be overestimated as
compared to the actual rainfall.

CHAPTER - 1
NATIONAL FLOOD FORECASTING NETWORK
1.1 FLOOD FORECASTING SERVICES
Flood causes considerable damage to human lives and property almost every
year. About one third of total flood prone area (40 mHa assessed by the Rashtriya Barh
Ayog) of the country has been provided with reasonable protection against flood of a
low magnitude due to techno-economic constraints; but there is no protection from
floods of higher magnitude. Since adoption of National Flood Policy by Government of
India in 1954, it was realized that a total protection against flood by structural means
alone is not possible and that optimum solution would consist of a mixture of structural
and non-structural measures. Therefore, stress has been laid on non-structural
measures like flood forecasting and warning, which is most important among such
means to minimize the damage potential from floods. Accurate and timely flood
forecasts and advance warning have, therefore, to be aimed for providing valuable
time to the people and to civil authorities in taking preventive measures like
evacuation, relief and rehabilitation measures, preparedness for flood fighting by
engineering authorities, etc. and thus mitigating such loses from floods.
1.2 FLOOD FORECASTING NETWORK IN THE COUNTRY
Flood Forecasting has been recognized as the most important and cost effective
non-structural measure for flood management. Recognizing the great importance of
this measure, flood forecasting of river Yamuna at Delhi was suggested by Reddy
Committee set up by the then Hon‟ble Prime Minister, Govt. of India to manage
flooding of Delhi. Accordingly in the year 1958, CWC commenced the flood forecasting
services in a small way by establishing flood forecasting unit for issuing water level
forecasts of the Yamuna for the National Capital, Delhi. On the recommendation of
various committees/ panels, a "Flood Forecast & Warning Organisation" was set up in
CWC in 1969 to establish forecasting sites on inter-state rivers at various flood prone
places in the country. 41 forecasting sites were added in 1969, making total number of
forecasting sites to 43. Extension of the services followed from time to time. The year-
wise positions of the number of flood forecasting sites till the flood season 2020 in the
network of Central Water Commission are shown in the Table - 1.1.

Central Water Commission through its twenty nine flood forecasting divisions
issued forecasts to the various user agencies, which includes various civil/ engineering
agencies of the States/ Central Governments such as Irrigation/ Revenue/ Railways/
public undertakings and Dam/ Barrage Authorities/ District Magistrates/ Sub Divisional
Officers besides the Defence Authorities involved in the flood loss mitigation work.
During the flood season, the Hon‟ble Minister of Jal Shakti, Government of India, the
Chairman and the Member (River Management) of Central Water Commission were
also being apprised of the latest flood situations in the above river basins in the
country.
1.3 CLASSIFICATIONS OF VARIOUS FLOOD SITUATIONS
The Central Water Commission has categorized various flood situations, for
monitoring the floods in the country through its level flood forecasting network, into
the following three different categories, depending upon the severity of floods i.e.
based on floods magnitudes.
6
(i) ABOVE NORMAL FLOOD
The river is said to be in ‘ABOVE NORMAL’ situation at any water level stations
when the water level of the river touches or crosses the warning level, but remains
below the danger level of the forecasting site.
(ii) SEVERE FLOOD
If the water level of the river touches or crosses its danger level, but remains
below the Highest Flood Level of the site (commonly known as „HFL‟) then the flood
situation is called the „SEVERE FLOOD’ situation.
(iii) EXTREME FLOOD
The flood situation is said to be ‘EXTREME FLOOD’ when the water level of the
river touches or crosses the „HIGHEST FLOOD LEVEL’ recorded at any water level
station so far.
1.4 STANDARD OPERATING PROCEDURE (SOP) FOR FLOOD FORECASTING

& WARNING
The basic activity of data collection, its transmission and dissemination of flood
forecasts to the local administration is carried out by the field divisions of CWC. The
modelling centres and Divisional Flood Control Rooms (DFCR) are located in the
premises of the field divisions. The field divisions perform these activities as per
existing Manual on Flood Forecasting which contains the following critical activities as
the general SOPs:
1. Nomination of Nodal Officers of CWC for interaction with the Nodal Officers of
concerned State Governments before monsoon every year.
2. Gearing up of flood forecasting network before monsoon every year.
3. Operation of Divisional Flood Control Room (DFCR) during monsoon every year.
4. Operation of Central Flood Control Room (CFCR) during monsoon every year.
5. Issue of flood forecasts to designated officers of concerned State and
transmission thereof through FAX/ Telephone/ E-mail/ Special Messengers during
monsoon every year.
6. Sending flood alerts through SMS on Mobile Phones to the concerned officers of
State/ Central Government during severe (3 hourly updates) and extreme (1
hourly updates) flood situations and uploading of Flood Forecasts and hourly
water level data in CWC‟s Flood Forecasting Website as per Standard Operating
procedure (SOP) for issuing alerts and electronic messaging in the event of
disaster situations issued by Ministry of Home Affairs from time to time.
For the purpose of dissemination of alerts to PMO/ Cabinet Secretariat, a uniform

system has been devised by categorizing each type of alert in stages- Yellow, Orange
and Red.
Categories of alerts for flood in respect of level forecasts is as indicated below.
7
Category Description Stage
Above Normal Flood (Water level between Warning level and Yellow
III
Danger level)
II Severe Flood (Water level below HFL and above Danger Level) Orange
Extreme Flood (Water Level equal and above Highest Flood Red
I
Level - HFL)
1.5 INFLOW FORECAST
Inflow Forecasts are issued for dams/ reservoirs/ barrages in various river basins
in the country. The project authorities have identified the threshold inflow limits for
issue of forecast considering various factors such as safety of the dam, status of
reservoir, downstream channel/ canal requirements. The inflow in volume during the
given duration indirectly indicates the possibility of accommodating the given volume or
otherwise in the reservoir. The outflow pattern is decided keeping in view of the safety
measures at the reservoir and the likely impact of the outflow from the reservoir to
cause damages/ difficulties in the downstream areas giving due attention to the
Emergency Action Plan (EAP) of the project. There is need for EAP for all reservoirs
covering normal operational releases and high releases during floods.
The salient features of all Flood Forecasting Sites, the details of all the sites
basin-wise as well as State-wise during the flood season 2020, is shown at Annex - I,
Annex – II(A&B) and Annex – III(A&B) respectively.
1.6 DATA COMMUNICATION SYSTEM
Central Water Commission maintains Wireless Stations for near real–time data
communication. These wireless sets work on pre-fixed schedules for receiving the vital
hydro-meteorological data immediately after its observation. In addition, telephone/
mobile phone, fax and internet are also used for dissemination of flood forecasts to
user agencies.
Now under modernization program, satellite based Telemetry System has been
installed at various stations for sensor based automatic data collection and satellite
based communication.
The installation of Telemetry System for automatic sensor based data collection
and satellite based data communication was initiated during IX Plan. At present, 934
telemetry stations have been installed.
In order to receive and analyses data collected by the telemetry stations, Earth
Receiving Stations and Modelling Centres have been installed in various parts of the
country during different Plan periods. There were 3 Earth Receiving Stations (ERS) in
the country at New Delhi, Jaipur and Burla. A total of 27 Modelling centres have been
installed in the country. The data reception is being monitored from Central Flood
Control Room at CWC Headquarter, New Delhi also.
8
The data received was used mainly by the divisions issuing forecast by MIKE-11.
Also, it is planned to transfer data observed through telemetry to WIMS software for
flood forecasting activities.
1.7 DAMAGE DUE TO FLOODS/ HEAVY RAINS BETWEEN 1953 TO 2020
The damage due to floods for the entire country was Rs. 15863.526 Crore
during the flood season 2019. The average annual damages to crops, houses and
public utilities from the year 1953 to 2019 as reported by the States/ UTs are of the
order of Rs. 6208.366 Crore. The maximum annual damage reported is Rs. 57291.098
Crore during 2018.
A comparative details showing the details of damages occurred during the flood
season 2018 to 2020 on different accounts, based on the reports (tentative), received

1.8 ANALYSIS OF PERFORMANCE OF FLOOD FORECASTING NETWORK
CWC carried out analysis and appraisal of the forecasting work, at the end of
monsoon season. Based on this, measures for improvements, if necessary, are
identified. A summary of the performance of the work carried out by the field Divisions
during the flood season 2020 has been presented in Chapter - 4. While the
performance of the flood forecasting system is satisfactory, yet there is constant
endeavor for improving the performance; especially for additional warning time as new
technology and more data are becoming available.
1.9 ORGANISATIONAL SET-UP OF FLOOD FORECASTING NETWORK
The present organizational set up of Flood-forecasting & Warning Establishment

of Central Water Commission under the Member (River Management) is spread over
regional offices of CWC each headed by a Chief Engineer. Sixteen Circle Offices and
twenty nine Divisions in its field formations carry out flood forecasting activities. Chief
Engineer (Flood Management) and Flood Forecast Monitoring Directorate monitor the
Flood Forecasting activities in the headquarters. It also issues flood bulletins at national
level.

CHAPTER – 2
ROLE OF IMD IN FLOOD FORECAST ACTIVITIES
2.0 ROLE OF IMD
CWC is the nodal agency for issuing Flood Forecast and IMD is the nodal agency for
issuing Quantitative Precipitation Forecast (QPF). The meteorological support is provided in
terms of ‘Quantitative Precipitation Forecast (QPF)’ through Hydro-met Bulletins. QPF bulletin is
issued at 930hrs IST and Hydro-met Bulletin at 1230hrs IST with further modification by FMOs.
Forecast for a lead time of 7-days (forecast for 3 days and outlook for subsequent 4 days) are
issued daily during flood season. QPF bulletins are further modified in the evening, if situation
demands. QPF Bulletins including heavy rainfall warning are also issued by concerned FMOs
during cyclone period or when there is a chance of heavy rainfall which may lead to flood in non-
flood season also.
Input comprises in terms of Hydro-met Bulletin which contains the following:

a. Synoptic situations
b. Spatial and temporal distribution of rainfall
c. Sub-basin wise categorical QPF for day-1, day-2 and day-3 as follows:
i) 0mm (ii) 0.1-10mm (iii) 11-25mm (iv) 26-50mm (v) 51-100mm (vi) >100mm
d. Outlook for the subsequent four days
e. Station wise recorded significant rainfall
f. Heavy rainfall warnings
g. Sub-basin wise past 24hrs realized rainfall
IMD has established 14 Flood Meteorological Offices (FMOs) at different parts of flood
prone areas of the country which are located at Agra, Ahmedabad, Asansol, Bhubaneswar,
Guwahati, Hyderabad, Jalpaiguri, Lucknow, New Delhi, Srinagar, Chennai, Bengaluru and
15
Patna which caters to the river catchments of Yamuna, Narmada, Tapi, Ajoy, Mayuraksi and
Kangasbati, Mahanandi, Brahmani and Subernarekha, Brahmaputra, Dhansiri and Barak,
Godavari and Krishna, Cauvery, Teesta, Ganga and Sharada, and Sahibi, Kosi, Baghmati,
Gandak, etc. IMD also provides similar support to Damodar Valley Corporation (DVC) for the
river basins Barakar and Damodar. Flood Meteorological Offices (FMOs, 14 in all over India) of
India Meteorological Department provide Meteorological support to Flood Forecasting
Divisions (FFDs) of Central Water Commission (CWC) to help them issue ‘Flood
warnings/Flood alerts’. The performance of QPF is verified for the monsoon season annually.
2.1 MODEL BASED QUANTITATIVE PRECIPITATION FORECAST
Sub-basin wise Quantitative Precipitation Forecast (QPF) using dynamical model WRF
ARW (9Kmx9 Km) based on 00UTC and 12UTC for day-1 to day-3, GFS (12kmx12km) based
on 00UTC for day-1 to day-7, NCUM (12kmx12km) for day-1 to day-7, Multi model Ensemble
(25kmX25km) based on 00UTC for day-1 to day-5 are computed and uploaded on the IMD’s
websitehttp://hydro.imd.gov.in/hydrometweb/(S(kkxivq454zpfjnzmak3d4q55))/PRODUCTS/QP
F /index.html for 153 flood prone river sub-basins. An example is shown in Fig. given below:
NWP Model based gridded daily rainfall forecast (WRF & GFS) are provided operationally
to CWC for their flood forecasting model. A new initiative has been taken to improve accuracy of
QPF. Sub basin wise dynamical models viz. GEFS and NEPS based Probabilistic QPF are being
generated daily and uploaded on the IMD website, which has been found very useful for under
heavy rainfall situations by the forecasters. An example is shown in Figs. given below.

2.2 SOUTHWEST MONSOON
India gets about 75% of its Annual rainfall during the Southwest monsoon season from
June to September except over some portions of southeastern parts of Peninsular India where
the main rains occur during the period of Northeast monsoon from October to December, which
overlap with the receding stage of the Southwest monsoon in October. Occasionally, cyclonic
storms develop in the South Bay and move into the Peninsula producing heavy rains during
Northeast monsoon season.
Southwest monsoon onsets over Kerala in the beginning of June and then advances
further. During the season, spells of heavy, very heavy and extremely heavy rainfall occur across
the country especially along the west coast of the Peninsula and on the southern slopes of Khasi
and Jaintia hills in Northeast India.
In association with Depressions which occasionally form in the North Bay of Bengal and
move west-northwestwards, heavy rains occur in the central parts of the country, Orissa,
Gangetic West Bengal, Bihar, East and West Madhya Pradesh, East Rajasthan and Gujarat
region.
A very important characteristic of southwest monsoon is the occurrence of "break". The

break situations arise when the monsoon trough shifts to the foothills of Himalayas and are very
important as these cause floods in the rivers rising from the Eastern Himalayas. Sometimes, the
phenomenon of break sets in immediately after a monsoon depression and occurrence of
associated intense rainfall activity takes place. These two causes occurring in succession serve to
intensify the floods.
The whole India has been divided into 36 meteorological subdivisions by India
Meteorological Department (IMD) for the purpose of description of rainfall/monsoon activities
and for forecasting purpose.
The performance of monsoon rainfall over the country is monitored by evaluating the
departures of area weighted total rainfall from the normal rainfall in respect of meteorological
districts, sub-divisions, State and Country as a whole. IMD has categorized the rainfall as Large
excess, Excess, Normal, Deficient and Large deficient according to the following criteria.
Large Excess: +60% or more of the normal

Excess : +20% to +59% of the normal
Normal: +19% to -19%of the normal
Deficient: -20% to - 59% of the normal
Large Deficient: -60% to -99% of the normal
No Rain (N.R.): -100% of the normal
Normal monsoon seasonal rainfall is defined as the Long Period Average say of 50
st th
years for the period from 1 June to 30 September. Presently, Long Period average for the
17
years 1961 to 2010 is being used to define normal. For the country as a whole the normal
st th
rainfall during the period from 1 June to 30 September is 88 cm.
2.3 HIGHLIGHTS OF SOUTH-WEST MONSOON 2020
 The seasonal (June-September) rainfall over the country as a whole was 109% of its Long
Period Average (LPA) in 2020. It was the third highest after 112% of LPA in 1994 and 110 %
of LPA in 2019.
 Seasonal rainfalls over Northwest India, Central India, South Peninsula and East & Northeast
(E & NE) India were 86%, 115%, 129% and 107% of their respective LPA.
 Out of 36 meteorological subdivisions, 2 subdivisions (5% of the total area of the country)
received large excess rainfall, 13 subdivisions (35% of the total area of the country) received
excess rainfall, 16 subdivisions (45% of the total area of the country) received normal
seasonal rainfall and 5 subdivisions (15% of the total area of the country) received deficient
season rainfall during the season.
 Monthly rainfall over the country as a whole was 117% of LPA in June, 90% of LPA in July,
127% of LPA in August and 105% of LPA in September.
 Southwest monsoon current reached south Andaman Sea and Nicobar Islands on 17th May
2020 (5 days ahead of its normal date), but further advance was sluggish. It set in over Kerala
on 1st June coinciding with its normal date for onset over Kerala; Monsoon covered the entire
country on 26th June 2020; 12 days before its normal date (8th July).
 Monsoon started withdrawing from western parts of northwest India on 28 th September 2020
against the normal date of 17th September 2020 with a delay of around 11 days. The
Southwest Monsoon withdrew from the entire country on 28th October 2020.
 During the season, one Severe Cyclonic Storm ‘NISARGA’ formed during 1st to 4th June. This
year also witnessed absence of monsoon depression during the season.
 The forecast for monsoon onset over Kerala for this year was correct, which is the fifteenth
consecutive correct forecast for the event (except for the year 2015) since issuing of forecast
for the onset over Kerala started in 2005. The Forecasted date of onset of monsoon over
Kerala was 5th June with a model error of ±4 days and realized date of onset of monsoon over
Kerala was 1st June in this year.
 The forecasts for the rainfall over the country as a whole during the season, forecasts for the
seasonal rainfall over three broad homogeneous geographical regions (Central India,
Northeast India and South Peninsula) and forecast for August rainfall and for rainfall of second
half of the monsoon season for the country as a whole were found to be underestimated with
respect to the actual rainfall whereas the forecasts for the rainfall for the country as a whole
18
during July and forecast for the seasonal rainfall for Northwest India were found to be
overestimated as compared to the actual rainfall.
2.4 ONSET AND ADVANCE OF SOUTHWEST MONSOON 2020
The South West Monsoon (SWM) arrived over Andaman Sea on 17th May 2020, 5 days
before its normal date of arrival, however its further advancement was hindered by the formation
and intensification of the Super Cyclonic Storm ‘Amphan’ over the Bay of Bengal. The SWM
arrived over Kerala on its normal date i.e. on 1st June. Further advancement over the country is
observed to be almost close to the normal date (with deviation of ±3-4 days) for most parts of
the central India. Advancement of the SWM over northwest India has taken place about 5-10
days earlier than the normal date. Monsoon covered entire country on 26th June against the
normal date of 08th July. Thus, monsoon set in over the entire country 12 days before its normal
date. Fig. 1 shows the isochrones of advance of monsoon 2020.

2.5 CHIEF SYNOPTIC FEATURES
During the monsoon season 2020, a total number of 12 Low Pressure System formed.
The first Low Pressure System formed over Arabian Sea on 31st May had intensified into Severe
Cyclonic Storm ‘NISARGA’ on 2nd June. However, none of the other low pressure systems
intensified into Monsoon Depression/Deep Depression categories during the monsoon season.
Month/System SCS Low Pressure Areas Well-marked low-pressure areas
June 1 01 0
July 0 01 01
August 0 01 04
September 0 02 01
The first Low Pressure System of the season; the Severe Cyclonic Storm ‘NISARGA’ originated
from a low pressure area which formed over Southeast and adjoining East Central Arabian Sea
and Lakshadweep area in the early morning of 31st May 2020. It concentrated into a Depression
over East central and adjoining Southeast Arabian Sea in the early morning of 1st June 2020. It
intensified further into a Deep Depression over East central Arabian Sea in the early morning and
20
into a Cyclonic Storm ‘NISARGA’ in the noon of 2nd June. It moved northwards till evening of 2nd
June and gradually recurved northeastwards and intensified into a Severe Cyclonic Storm in the
early morning of 3rd June. Continuing to move northeastwards, it crossed Maharashtra coast
close to south of Alibaug as a Severe Cyclonic Storm during the afternoon of 3 rd June.
Continuing to move northeastwards after landfall, it weakened into a Cyclonic Storm in the
evening over north Madhya Maharashtra and into a Deep Depression in the midnight of 3 rd June
over the same region. It further weakened into a Depression over western parts of Vidarbha and
neighbourhood in the early morning and into a Well-Marked Low pressure over central parts of
Madhya Pradesh in the evening of 4th June. It weakened further into a Low pressure area over
southeast Uttar Pradesh and adjoining Bihar in the afternoon of 5th June. Track of Severe
Cyclonic Storm ‘NISARGA’ formed during SW Monsoon season is given in Fig. 2.
Fig. 2: Track of the Severe Cyclonic Storm ‘NISARGA’ formed during Monsoon Season
During the month of June, apart from the above system, a low pressure area which
formed over West central Bay of Bengal (9-12 June) and its associated cyclonic circulation have
strengthened the monsoon flow. Cyclonic vortices at upper levels off both the coasts, over
central & north India, east-west shear zone across Peninsular India, an east-west trough at mean
sea level extending upto lower tropospheric levels with cyclonic circulations embedded in it were
also observed. All these systems caused fairly widespread to widespread rainfall activity over
most parts of the country and thus supported the advance of monsoon over the country.
21
Towards the end of the month, the monsoon trough shifted northwards with its eastern part
close to the foot hills of Himalayas (during 27 June-2 July).
During the month of July, many unfavorable features of monsoon appeared resulting in
deficient rainfall for the country. The weak monsoon in July was mainly due to absence of any
major monsoon disturbance over Bay of Bengal and due to the prevalence of a weak cross
equatorial flow in general. Absence of any major systems caused the monsoon trough also weak.
The monsoon trough lay to the north of the normal position or close to the foothills of the
Himalayas on many days during the month. It resulted in frequent and prolonged floods over
northeastern India, Bihar and adjoining areas of East Uttar Pradesh. At the same time, major
parts of central and northwest India received deficient rainfall.
However, in the first week of July, with the formation of two low pressure areas; one over
coastal Saurashtra and neighbourhood (5-12 July) and the other over Northwest Bay of Bengal
off Odisha-Gangetic West Bengal coast (5-6 July) and their associated cyclonic circulations tilting
southwards with height, monsoon trough was observed in its normal/south of its normal position
during 3-8 July. The low pressure area which formed over coastal Saurashtra and
neighbourhood, became well marked on 6th over Kutch and neighbourhood. In addition to this
low pressure area, an off- shore trough, a shear zone along 16° N and the monsoon trough to
the south of its normal position resulted in widespread rainfall activity over Gujarat State and
over coastal & interior parts of Maharashtra and the other low pressure area over Bay of Bengal
caused widespread rainfall activity over eastern parts of India.
During the subsequent three weeks of July, an off-shore trough along south Maharashtra
and Kerala coasts, cyclonic vortices over north Konkan coast and east-west shear zone across
peninsular India caused widespread/fairly widespread rainfall with heavy to very heavy rainfall
activity along the west coast and adjoining interior parts of peninsular India. In the same period,
the interactions of the eastern end of monsoon trough (which lay north/close to foot hills of
Himalayas) with the cyclonic circulations and convergence of strong south-westerly to southerly
winds from Bay of Bengal over east and northeast India triggered monsoon activity over
northeast and adjoining east India. The interaction of western end of monsoon trough with the
systems in westerlies, circulations in the lower tropospheric levels and moisture incursions from
the Arabian Sea caused widespread/fairly widespread rainfall with heavy rainfall over Western
Himalayan Region, plains of northwest India & adjoining central & west India during third and
fourth week of the month.
A coherent Madden Julian Oscillation (MJO) signal was not evident during June and on
most days of July. Only towards the end of July upto mid of August, the signal became active
and slight eastward propagation from Indian Ocean to the maritime continent was seen.
In association with absence of low pressure systems over the Bay of Bengal, shifting of
monsoon trough to the foothills on many days and unfavourable conditions like MJO, the
monsoon rainfall was deficient in July across central India. At the same time it caused flood over
northeastern States, Bihar and East Uttar Pradesh on a few occasions.
22
As the MJO moved eastwards over the Indian seas, the Arabian Sea and Bay of Bengal
became convectively active in August. The formation of five low pressure systems over the North
Bay of Bengal in succession out of which four of them became well marked (4-10 , 9-11, 13-18,
19-26 and 24-31 August) and their west-northwestward movement across central India upto
Gujarat and south Rajasthan, active MJO, active Monsoon trough mostly south of its normal
position and stronger winds reaching up to 50-60 kmph in lower levels over Arabian Sea during a
few days in the month led to active monsoon conditions over most parts of the country and
caused significantly higher than normal rainfall over central and western parts of India during the
month of August.
During the month, strengthening of the monsoon flow in the Arabian Sea, led to
convergence of strong low level westerlies along the west coast. Also, the presence of cyclonic
vortices, off-shore trough, east-west shear zone over peninsular India caused widespread
rainfall/thundershowers along the west coast, over parts of Peninsular India, Gujarat state,
Konkan & Goa and Madhya Maharashtra. System in westerlies and convergence of moist low
level winds from Arabian Sea, cyclonic circulations over northwest India and presence of strong
easterlies due to the presence of low pressure systems caused scattered to fairly widespread
rainfall/thunderstorms over Western Himalayan Region and adjoining parts of northwest India
during the month.
Due to active monsoon conditions, riverine floods occurred over Odisha, Telangana,
Madhya Pradesh, Maharashtra, Gujarat and Rajasthan. The active monsoon conditions
consecutively for 4 weeks led to excess rainfall activity over the country.
Fairly widespread to widespread rainfall/thunderstorms over parts of Northeast and

adjoining parts of East India with heavy to very heavy rainfall was also observed during the first,
second and the last week of August due to the convergence of moist south-westerlies to
southerlies from the Bay of Bengal and presence of cyclonic vortices in the lower levels.
A weak MJO re-entered eastern Indian Ocean in late August and propagated eastwards
into maritime continent with weak amplitude by the end of monsoon season.
From the last week of August till the formation of a low pressure area off north Andhra
coast on 13 September, either the western or the eastern end of monsoon trough remained
north of its normal position or close to foot hills of Himalayas. Heat Low also started weakening.
The low pressure area which formed on 13th September subsequently became Well Marked Low
and dissipated over Telangana and adjoining south Chhattisgarh. It triggered monsoon activity
over Central and Peninsular India. After the dissipation of the low pressure area on 16 th, the
monsoon trough lay north of its normal position and regained it near-normal position with the
formation of another low pressure system on 20th over Northeast Bay of Bengal and
neighbourhood. This low pressure system dissipated over east Bihar and neighbourhood on 26 th.
East Uttar Pradesh, Bihar and Sub Himalayan West Bengal experienced widespread
rainfall/thunderstorms due to this system. The monsoon trough became disorganized on 28th
September. Apart from the above two low pressure systems in the month, another low-pressure
system (6-8 September) formed over Southeast and adjoining East central Arabian Sea and in
23
conjunction with an east-west shear zone over south peninsula caused widespread rainfall
activity over south Peninsular India, Lakshadweep area and coastal and interior parts of
Maharashtra during the first week of the month. Circulation features favoring convergence of
strong moist winds from the Bay of Bengal in the lower tropospheric levels and the alignment of
monsoon trough over northeast India and adjoining east India continued to trigger the monsoon
activity over the region during the month.
2.6 WITHDRAWAL OF SOUTHWEST MONSOON
The formation of two low pressure areas in the month of September led to an active
monsoon trough which delayed the withdrawal of monsoon. The withdrawal of monsoon
commenced on 28th September from some parts of west Rajasthan and Punjab, against its
normal date of 17th September with the establishment of an anti- cyclonic circulation in the lower
tropospheric levels over western parts of northwest India and substantial reduction in moisture
content & rainfall. A further change in the low level wind pattern into north westerlies, reduction
in moisture content and cessation of rainfall over northwest India, led to the withdrawal of
southwest monsoon from some more parts of Rajasthan, remaining parts of Punjab, entire
Western Himalayan region & Haryana, Chandigarh & Delhi and some parts of Uttar Pradesh on
30th September. It then withdrew from most parts of Rajasthan, some more parts of Uttar
Pradesh and some parts of northwest Madhya Pradesh on 3rd October 2020 and from remaining
parts of Rajasthan, some more parts of Uttar Pradesh and Madhya Pradesh, most parts of
Gujarat state and some parts of North Arabian Sea on 6th October 2020. The Southwest Monsoon
withdrew from the entire country on 28th October 2020. Fig. 3 shows the isochrones of
withdrawal of monsoon 2020.

2.7 HIGH IMPACT WEATHER EVENTS
Fig. 4 depicts the meteorological Sub-divisions or parts thereof, which experienced high
impact weather events like floods, landslides and Heat waves during the Southwest Monsoon
season (June - September) along with the dates. It also indicates areas that experienced isolated
extremely heavy rainfall (Rainfall amount ≥25 cm reported during the 24 hours ending at 0830
hrs IST) events during the season without any reference to the dates of these occurrences.
Incessant rainfall associated with the formation and movement of the monsoon low
pressure systems in the presence of strong cross equatorial flow often caused flood situations
over various areas during different parts of the season.

2.8 RAINFALL DISTRIBUTION
The realized 2020 southwest monsoon season (June to September) rainfall over the
country as a whole and four broad geographical regions are given in the table below along
with respective long period average (LPA) values. The rainfall during the 4 monsoon months
and the second half of the monsoon season (August & September) over the country as a
whole are also given.
Season (June to September) rainfall

Long Period Average Actual Rainfall for 2020
Region (LPA) (mm) Rainfall (mm) Rainfall (% of LPA)
All India 880.6 961.4 109
Northwest India 599.5 516.5 86
Central India 976.6 1122.4 115
East & Northeast India 1410.4 1509.0 107
South Peninsula 726.2 937.4 129
Monthly & second half of monsoon season rainfall (All India)
Month LPA (mm) Actual Rainfall for 2020
Rainfall (mm) Rainfall (% of LPA)
June 166.9 195.6 117
July 285.3 257.1 90
August 258.2 327.8 127
September 170.2 178.0 105
August +September 428.4 505.8 118
As seen in the table above, the 2020 season rainfall over the country as a whole
(109% of LPA) was more than the long period average (LPA). The 2020 seasonal rainfalls
over three of the four geographical regions of the country (except Northwest India) were
also more than the respective LPAs. The highest rainfall (129% of LPA) was received by
South Peninsula and lowest rainfall (86% of LPA) was received by Northwest India. Central
India and East & Northeast India received season rainfalls of 115% of LPA and 107% of LPA
respectively. The monthly rainfall over the country as a whole were more than LPA during
three months of the season (117% of LPA in June, 127% of LPA in August and 105% in
September) and were less than LPA during the months of the July (90% of LPA in July).
Country as a whole received rainfall of 109% of LPA during the first half (117% of LPA
in June and 90% of LPA in July), which was less than that during the second half (118% of
LPA) with 127% of LPA in August and 105% of LPA in September. Thus among the four
months, rainfall deficiency was highest during July and rainfall was excess in August.
2.9 INDIAN NORTHEAST MONSOON
The Indian southwest monsoon (SWM) season of June to September is the chief rainy
season for India and about 75% of the country’s annual rainfall is realised during this season.
26
Subsequent to the withdrawal of SWM, the northeast monsoon (NEM), a small scale monsoon
confined to parts of southern peninsular India comprising of the meteorological sub-divisions of
Tamil Nadu, Puducherry & Karaikal (TN), Kerala & Mahe (KER), Coastal Andhra Pradesh &
Yanam (CAP), Telangana, Rayalaseema (RYS) and South Interior Karnataka (SIK) occurs. For
the subdivision of TN, the normal SWM seasonal rainfall realised is only about 36% (336.1 mm)
of its annual rainfall (939.3 mm) as this subdivision comes under the rain-shadow region during
the SWM. The northeast monsoon (NEM) season of October to December (OND) is the chief
rainy season for this sub-division with approx 48% (449.7 mm) of its annual rainfall realised
during this season and hence its performance is a key factor for this regional agricultural
activities.
Further, the NEM season is also the primary cyclone season for the North Indian Ocean
(NIO) basin comprising of the Bay of Bengal (BOB) and the Arabian Sea (AS). Cyclonic
disturbances (CDs; low pressure systems (LPS) with maximum sustained surface wind speed
(MSW) of 17 knots or more forming over BOB and moving west/northwest wards affect the
coastal areas of southeastern peninsular India and also contributes significantly to NEM rainfall.
As such, the NEM season assumes importance from the agricultural and Water Management as
well as disaster management perspectives.
Prior to the commencement of NEM rains, after the withdrawal of SWM up to 15°N,
reversal of low level winds from southwesterly to northeasterly occurs. The normal date of
setting in of easterlies over the southeastern peninsular India is 14 th October. The normal
rainfall received over the five NEM sub-divisions during OND is TN- 449.7 mm, KER- 491.6 mm,
CAP- 338.1 mm, RYS- 223.3 mm, Telangana- 123.3 mm and SIK- 204.1 mm. However, the
NEM seasonal rainfall shows a high degree of variability with 27% co-efficient of variation.
The NEM rainfall is influenced by global climate parameters such as ENSO (El Nino/La Nina &
Southern Oscillation Index), Indian Ocean Dipole (IOD) and Madden-Julian Oscillation (MJO). El
Nino, positive IOD and MJO in phase 2-4 with amplitude greater than one are generally
associated with good NEM rainfall.
2.10 ONSET PHASE
During October 2020, La Nina and positive SOI conditions prevailed over the equatorial Pacific
region; IOD was neutral and MJO was generally in phase 5-8. As such La Nina & positive SOI,
and MJO in the western hemisphere were not favourable for good NEM activity. Further, two low
pressure systems over the BOB- (i) a Deep Depression (DD) during 11th -14th October 2020 that
crossed north Andhra Pradesh coast near Kakinada and (ii) a Depression (D) during 22 nd - 24th
October 2020 that crossed West Bengal–Bangladesh coasts extended the southwest monsoon
activity upto the last week of October 2020.
2.11 SYNOPTIC SCALE WEATHER SYSTEMS DURING THE NEM-2020 SEASON
Cyclones and Depressions over the Bay-of Bengal during October-December 2020,
six major low pressure systems (LPS) formed over the NIO – four over the BOB and two over the
27
AS. Of these the four LPS that formed over the BOB influenced the NEM activity. Brief life history
of these four LPS (based on the preliminary reports on these LPS of RSMC, IMD New Delhi) - (i)
Deep Depression over the BOB during 11th – 14th October 2020 (ii) Depression over the BOB
during 22nd – 24th October 2020 (iii) Very Severe Cyclonic Storm (VSCS) NIVAR over BOB during
22nd – 26th November 2020 and (iv) Cyclonic Storm (CS) BUREVI over the BOB during 30 th
November – 05th December 2020.
2.12 OTHER SYNOPTIC SCALE WEATHER SYSTEMS
Aside from the cyclones and depressions that affected the performance of NEM 2020,
other major synoptic scale weather systems that influenced the NEM 2020 were the transient
easterly wave troughs across the peninsular India. During the period October-December 2020,
frequent easterly wave troughs that moved across peninsular India from east to west
contributed significantly to the NEM rainfall during the season. Analysis of Hovmoller plots of 6-
hrly meridional wind along 10°N latitude at 700 hPa for the period 1 st October–31st December
2020 indicated four easterly wave troughs that moved across the peninsular India– (i) 8th - 12th
November 2020, (ii) 12th - 16th November 2020, (iii) 12th - 16th December 2020 and (iv) 26th -
30th December 2020.
2.13 SUMMARY
The onset of NEM 2020 over the southeastern parts of peninsular India took place on 28 th
October [delay of 8 days from the normal date of onset (20th October)]. Despite a late onset,
except Kerala, all other subdivisions benefited by the NEM (TN, CAP, RYS & SIK) received
normal to excess rainfall during the season (Oct-Dec 2020). Under the influence of extended
SWM, CAP, RYS & SIK received normal rainfall in October, but, TN & KER ended up deficient
during the month. In November, except KER, which came under deficient category, all other
subdivisions received normal/above normal rainfall with RYS recording +122% excess. In
December all the five subdivisions received normal/above normal rainfall with RYS and TN
recording +99% and +87% excess rainfall. Two cyclones– VSCS Nivar and CS Burevi as well as
passage of easterly wave trough across peninsular India contributed significantly towards NEM
activity during November and December. The NEM season extended into first half of January
2021 also and cessation of NEM rains over the peninsular India took place on 19th January
2021.

CHAPTER - 4
FLOOD FORECAST PERFORMANCE
4.1 FLOOD FORECASTING EVALUATION - CRITERIA & PROCEDURE
A number of techniques are being utilised for formulation of river stage and inflow
forecasts by Central Water Commission. While inflow forecast is being provided for
assisting project authorities in reservoir regulation, the stage forecast is done for warning
the civil and engineering authorities about the predicted water level well ahead of its
occurrence. An accurate forecast is one where the forecast level and corresponding actual
observed level exactly synchronize or have such a small difference that it can be taken as
reasonably accurate. In an ideal situation, not only the forecast and the corresponding
observed value of river stage/inflow should be the same but also the time of such
occurrence should be the same as that predicted.
4.2 EVALUATION CRITERIA FOR STAGE/INFLOW FORECASTING
As per present practice, all the level and inflow forecasts are being judged by the
single criteria of accuracy i.e. the actual level attained is within ±15cm of forecasted value
for stage forecasts and the actual inflow/volume received in the dam/barrage is within
±20% of the forecasted value for inflow forecast.
The forecast of incoming flood gives the water level or inflow and ‘time’ of
occurrences. It is also observed that in many cases the levels attained were found within
permissible limit of accuracy but the time of occurrence was not the same.
4.3 FLOOD FORECASTING ACTIVITIES
The flood forecasting activities like data collection, forecast formulation and its
dissemination during 2020 covered various river basins and States. A total of 11721
forecast were issued during 2020. The performance of flood forecasting Division wise,
