Deadliest weather event and tropical cyclone (hurricane): Bangladesh on November 12-13, 1970, when a storm killed an estimated 300,000 people.
The storm sometimes known as the "Great Bhola Cyclone" caused between 300,000 and 500,000 deaths when the storm surge overwhelmed island and tidal flats along the Bay of Bengal.
Deadliest tornado: Manikganj district, Bangladesh on April 26, 1989, which killed 1,300 people.
The 1989 tornado had a track about a mile wide and destroyed two towns, injuring over 12,000 and leaving about 80,000 people homeless.
Deadliest indirect lightning strike: Dronka, Egypt on November 2, 1994, when 469 people were killed by a lightning-caused oil fire.
In 1994, a flash of lightning caused a fire that ignited three oil tanks, each holding about 5,000 tons of aircraft or diesel fuel. The railway line holding the tanks collapsed in a flood and floodwaters carried the blazing fuel into Dronka.
Deadliest lightning strike: Manical Tribal Trust Lands in Zimbabwe on December 23, 1975, which killed 21 people.

"Men caught in the open and without shelter were simply pounded to death by the hail. Fourteen bodies were found in the race-course. More than one marriage party were caught by the storm near the banks of the river, and were annihilated. The police report that 1,600 head of cattle, sheep, and goats were killed,” wrote John Eliot, the first director-general of the India Meteorological Department, according to the WMO report.
