Damage, injuries and deaths
National Weather Service offices recorded about $53,000 in property damage from hail, thunderstorm wind and tornadoes across the US on this storm day (12 events in 8 states). 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.
