Super Cyclonic Storm Amphan was a powerful and deadly tropical cyclone that caused widespread damage in Eastern India and Bangladesh in May 2020. It was the strongest tropical cyclone to strike the Ganges Delta since Sidr of the 2007 season and the first super cyclonic storm to occur in the Bay of Bengal since the 1999 Odisha cyclone. Causing over US$13 billion of damage, Amphan is also the costliest cyclone ever recorded in the North Indian Ocean, surpassing the record held by Cyclone Nargis of 2008.
