During the morning of 16 May, cyclonic storm Mahasen made landfall in Patuakhali district in southern Bangladesh and weakened as it advanced and a predicted storm surge was avoided due to low tide. It hit ten west central coastal districts on 16 May, affecting 1,285,508 people and leaving 13 people dead. Of the ten coastal districts hit, the three districts of Patuakhali, Bhola and Barguna are the worst affected as the cyclone makes landfall. As of 15 May, approximately 1.1 million people were evacuated to cyclone shelters. Some of the evacuated populations have started returning to their homes, while the remainder are still in cyclone shelters as the homesteads are flooded with tidal surges caused by the cyclone. As per the government’s initial information as of 17 May, a total of 49,178 houses have been completely destroyed and 45,825 houses are partially destroyed.
Since 12 May, a total of 49,365 cyclone preparedness programme (CPP) volunteers have been mobilized in the 13 coastal districts. The CPP volunteers were engaged in disseminating alert messages to coastal communities to prepare them for safe evacuation and advised fishermen not to sail to the deep sea. The Bangladesh Red Crescent Society (BDRCS) has been conducting search and rescue operations, giving first aid, and distributing food and clean water to the affected population, especially in the remote islands of Patuakhali, Bhola and Barguna districts.
