Moderate Tropical Storm Dumako was a weak tropical cyclone that caused moderate damage in Madagascar. The fourth disturbance and fourth named storm of the 2021–22 South-West Indian Ocean cyclone season, it was the third storm to make landfall on Madagascar in 2022 after Ana and Batsirai.
On 10 February, a zone of disturbed weather formed over the central South Indian Ocean. One day later, the JTWC recognized it as Invest 94S.[1][2] On the same day at 18:00 UTC, MFR designated the system as a tropical disturbance. A day later, the MFR upgraded the disturbance to a tropical depression. The JTWC issued a Tropical Cyclone Formation Alert for this system. On 13 February, the JTWC recognized the system as Tropical Cyclone 12S at 06:00 UTC. At 18:00 UTC, the MFR upgraded the system to a moderate tropical storm and designated it as Dumako.[3] The storm continued intensifying, and at 06:00 UTC on February 14, Dumako reached its peak intensity as a moderate tropical storm, with maximum 10-minute sustained winds of 85 km/h (55 mph), maximum 1-minute sustained winds of 95 km/h (60 mph), and a minimum central pressure of 993 hPa.[4][5] Around 12:00 UTC, Dumako made landfall as a moderate tropical storm near Sainte-Marie Island, Madagascar with winds of 65 km/h (40 mph). Afterward, due to land interaction, the storm began to weaken. After a few hours, it weakened into a tropical depression. It entered the Mozambique Channel before dissipating on 18 February.[citation needed]
