- Intense Tropical Cyclone Dumazile was a strong tropical cyclone that brought flooding to Madagascar and Réunion in early March 2018. Dumazile originated from an area of low pressure that formed in the South-West Indian Ocean near Agaléga on 27 February. The system concentrated into a tropical disturbance on 2 March and was named the next day, as it intensified into a tropical storm. Amid conditions conducive for intensification, Dumazile strengthened over the next two days and reached peak intensity on 5 March as an intense tropical cyclone, with 10-minute sustained winds of 165 km/h (105 mph), 1-minute sustained winds of 205 km/h (125 mph), and a central pressure of 945 hPa (27.91 inHg). The system weakened steadily over the next couple of days because of increasing wind shear as it tracked to the southeast. Dumazile became post-tropical on 7 March and eventually dissipated completely on 10 March near the Kerguelen Islands. Cyclone Dumazile affected Réunion less than two months after Cyclone Berguitta, halting ongoing repairs to bridges and reconstruction efforts. Torrential rainfall, reaching 1,600 mm (63 in) in Salazie, caused significant flooding across the island. Floodwaters, landslides, and downed trees caused significant damage and disruption to the road network on Réunion, particularly in coastal and mountainous areas. Repairs to the highway between Îlet Furçy and Cilaos were set back significantly. Large waves along the coast caused erosion, leading to collapses of beachfront infrastructure and beach closures. Ports were also damaged by the waves, and the Port of Saint-Gilles was clogged by debris. The agricultural sector incurred about €3 million (US$3.73 million) of damage, as crops were destroyed by floods and gusty winds. Recovery in Réunion was later hampered further by Cyclone Fakir in April. The northern and eastern coasts of Madagascar experienced about 210 mm (8.3 in) of rain. Flooding occurred in Toamasina as a result of malfunctioning drainage systems that had been damaged by Cyclone Ava in January. Parts of the city lost power during the storm. Severe flooding in the Diana Region blocked roadways, inundated homes, and damaged crops. The RN6 highway in particular experienced several accidents and breakdowns, and a 18 m (59 ft) section of the road collapsed. Strong winds in coastal towns resulted in fallen trees, beach erosion, and damage to property and infrastructure. The Ambalavola District was left underwater, with sewage flowing through neighborhoods. Two people died in Madagascar during the storm: one in Ankorondrano and the other in Ambatoroka. (en)

- 强烈热带气旋杜马奇尔（英語：Intense Tropical Cyclone Dumazile）是2018年3月上旬在马达加斯加和留尼汪引发洪灾的强烈熱帶氣旋，2月27日由西南印度洋阿加萊加群島附近的低气压区发展而成。系统3月2日凝聚成热带扰动，次日升级热带风暴并获名。此后两天杜马奇尔因外界环境有利迅速增强，3月5日达到十分钟持续风速每小时165公里、一分钟持续风速每小时205公里、中心气压945毫巴（百帕，27.91英寸汞柱）最高强度，属强烈热带气旋。此后几天风切变增强，向东南移动的杜马奇尔稳步减弱，3月7日转为後熱帶氣旋并于3月10日在凯尔盖朗群岛附近消散。 杜马奇尔在氣旋貝吉塔不到两个月后吹袭留尼汪，重建和桥梁修复工程暂停。倾盆大雨在全岛各地引发重大洪灾，降雨量高达1600毫米。洪水、山体滑坡、树木倒塌重创留尼汪公路网，对山地和沿海地区交通影响尤为严重，部分公路修复工作大幅倒退。大浪侵蚀海岸令海滨基础设施坍塌、海滩封闭。海浪还令港口受损，垃圾堵塞港。洪水与狂风摧毁庄稼，农业损失约三百万欧元。留尼汪四月又遭受摧残，对灾后恢复雪上加霜。 马达加斯加北岸和东岸降雨量约210毫米，图阿马西纳因一月受损的排水系统不堪重负引发洪灾，风暴期间部分市区停电。重大洪灾在第亞那區阻塞道路、淹没民宅，还令农作物受损。灾情特别严重，18米道路坍塌，还发生多起事故和故障。狂风刮倒沿海城镇的树木并侵蚀海滩，房屋和基础设施受损。洪水淹没安巴拉沃拉区，污水流经众多社区。风暴夺走马达加斯加两条人命，安科隆德拉诺和安巴拉沃拉各一人。 (zh)
