Damage, injuries and deaths
National Weather Service offices recorded about $90.6 million in property damage and 57 injuries from hail, thunderstorm wind and tornadoes across the US on this storm day (110 events in 14 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.
