Damage, injuries and deaths

National Weather Service offices recorded 36 hail, wind or tornado events across the US on this storm day, with no damage estimate, injury or death entered. Before 1996 the database holds only tornado, hail and wind events, and damage was often entered as a range, so treat these figures as rough. Injuries and deaths are those the events caused directly.
