Deadliest hailstorm: Moradabad, India, on April 30, 1888, which killed 246 people.

Reportedly there were hailstones the size of "goose eggs and oranges and cricket balls." The WMO report cites an eyewitness who said that roofs collapsed and doors and windows were smashed by the ice.

"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.
