The record

Events: 32,966
Deaths: 1,341
Injuries: 3,711
Damage: $98 billion

Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

Every year

Tap a year for every episode in it.

From 1996 the record holds 48 kinds of event with each office’s narrative; before that, tornadoes, hail and thunderstorm wind only, and before 1955 tornadoes alone.
