Tropical cyclones affecting Bangladesh have killed about 1.54 million people in the Bengal region.

Bangladesh Space Research and Remote Sensing Organisation (SPARRSO), a government agency under the Ministry of Defence^[1] provides storm predictions and early warnings using feeds from NASA and NOAA's satellites. The warnings are usually given in a scale of 10, with 10 being used for the deadliest storms.

A detailed program for storm prevention was outlined by the government following the cyclone of 1991. A Comprehensive Cyclone Preparedness Programme (CPP) is jointly planned, operated, and managed by the Ministry of Disaster Management and Relief and the Bangladesh Red Crescent Society; a volunteer force of more than 32,000 are trained to help in warning and evacuation in the coastal areas.^[2] Around 2,500 cyclone shelters have been constructed in the coastal regions. The shelters are built on elevated platforms and serve the dual role of schools or community centers during normal weather. In Patenga, Chittagong, the coast has been heavily protected with concrete levees. Also, afforestation has been initiated in the coastal regions to create a green belt.
