The Daulatpur-Saturia tornado struck Bangladesh in 1989.
The tornado formed at about 12:30 UTC on April 26, 1989, in Manikganj District. It touched down near Daulatpur and traveled eastward before reaching Saturia, cutting a track roughly 80 kilometers long. The most severe destruction occurred across an area of about 150 square kilometers.
The event developed during Bangladesh’s dangerous pre-monsoon severe-weather season. A clash between warm, moist air from the Bay of Bengal and cooler, drier air from the Himalayas created instability, while powerful upper-level winds supplied the wind shear needed for rotating thunderstorms. The region had also experienced drought for about six months.
Some accounts describe the tornado as F3, while wind estimates of roughly 338–419 km/h suggest F4 intensity on the Fujita scale. The disaster is also remembered for its enormous and uncertain death toll: the World Meteorological Organization has cited approximately 1,300 deaths and 12,000 injuries.
