Present day Bangladesh, due to its unique geographic location, suffers from devastating tropical cyclones frequently.
The funnel-shaped northern portion of the Bay of Bengal amplifies the storm surge of landfalling tropical cyclones, affecting thousands of people.
Some of the most devastating natural disasters in recorded history with high casualties were tropical cyclones that hit the region now comprising present-day Bangladesh.
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.
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.
The shelters are built on elevated platforms and serve the dual role of schools or community centers during normal weather.
