Part of the 2024–25 South-West Indian Ocean cyclone season

Intense Tropical Cyclone Chido is an ongoing tropical cyclone currently affecting Madagascar and threatening Comoros, Mayotte and Mozambique. The fourth tropical disturbance, the second tropical cyclone, and the second intense tropical cyclone of the 2024–25 South-West Indian Ocean cyclone season, Chido formed from a tropical disturbance southeast of Diego Garcia that was first noted on 5 December 2024. It continued westward, and steadily intensified before being named Chido on 8 December. After it underwent rapid intensification, Chido made landfall at Agaléga in Mauritius on 11 December, peaking in intensity the following day.

On 5 December, the MFR noted that a tropical disturbance formed southeast of Diego Garcia. The JTWC began tracking the system later that day. Late on 7 December, the MFR designated the system as Tropical Depression 04. At 18:00 UTC the following day, the system intensified into Tropical Storm Chido. Chido continued to strengthen, eventually becoming a Severe Tropical Storm later on 10 December. On 11 December, Chido developed an eye, and rapidly strengthened into a category 4-equivalent intense tropical cyclone, as it made landfall at Agaléga in Mauritius, making Chido the strongest tropical cyclone to directly affect the island since Cyclone Andry in 1983.[1] The next day, Chido intensified further, peaking as an intense tropical cyclone, with 1-minute sustained winds exceeding 155 mph (249 km/h).

Preparations

In Agaléga, Mauritius, residents in sought refuge at an airport terminal.[2] The United Nations Office for the Coordination of Humanitarian Affairs said that over 1.7 million people Mozambique could be affected by winds exceeding 120 km/h (75 mph), and that the cyclone may exacerbate a cholera outbreak affecting the country.[3] Authorities in Zimbabwe said that Chido was likely to affect the country by 17 December, with heavy rainfall, flooding and landslides likely.[4]

Impact

Agaléga, Mauritius was reportedly "devastated" by Chido, with 150 km/h (93 mph) gusts and an 8 m (26 ft) storm surge destroying most of the island's homes and schools.[5][2]
