Official estimates from the World Meteorological Organization indicate that it killed approximately 1,300 people, which would make it the deadliest tornado in history.

During this time, convective available potential energy—an indicator of atmospheric instability whereby higher values denote a greater likelihood of thunderstorms—and wind shear are conducive to the development of rotating thunderstorms.

On that day, another low approached from Madhya Pradesh, and in conjunction with a ridge over China, the pressure gradient became tighter across Bangladesh.

The jet stream became particularly intense on 26 April, with a sounding from Dhaka observing 240 km/h (150 mph) winds at a height of 10.6 km (35,000 ft).

[10] In 2022, this death toll was challenged in a paper authored by Dr. Fahim Sufi with the Australian Government, Dr. Edris Alam with the University of Chittagong, and Dr. Musleh Alsulami with the Umm al-Qura University, where it was stated the deadliest tornado in Bangladesh history was the 14 April 1969 Dhaka, Bangladesh tornado, which killed 922 people.

[3] Damage was extensive, as countless trees were uprooted and every home within a six square kilometer area of the tornado's path was completely destroyed.

[1] An article in the Bangladesh Observer stated, "The devastation was so complete, that barring some skeletons of trees, there were no signs of standing infrastructures".
