Damage, injuries and deaths

National Weather Service offices recorded about $3.4 million in property damage and 38 injuries from hail, thunderstorm wind and tornadoes across the US on this storm day (21 events in 6 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.
