January 21, 2023 - Tropical Storm Cheneso


On the morning of January 19, 2023, Tropical Storm Cheneso made landfall on the northeastern coast of Madagascar, just north of Antalaha Town in Sava Region, carrying maximum sustained winds of about 66 mph (106 km/h). According to ReliefWeb, early assessments on January 19 reported 1 death and 1 missing person. An additional 2,224 people were estimated to be impacted by the storm, including those evacuated prior to the arrival of Cheneso.

Once on shore, the storm quickly began to weaken, but it also began to slow forward motion, bringing sustained wind and heavy rain to the region. The Joint Typhoon Warning Center (JTWC issued its last advisory on the system at 0900 UTC (12:00 noon local time) on January 19, when winds had dropped to 51 mph (82 km/h). At that time, the center of Cheneso was located 374 miles (600 km) north-northeast of Antananarivo, Madagascar and was tracking westward. The tropical storm was expected to dissipate quickly, with remnants tracking over land until at least January 21.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired a true-color image on January 19, near the time of landfall, when the large cloud-filled center of the storm covered most of the northern tip of Madagascar. Large convective bands were bringing rain to nearly half of country, as well as to the Comoros Islands northwest of Madagascar.
