Damage, injuries and deaths
National Weather Service offices recorded about $15.9 million in property damage, 65 injuries and 2 deaths from hail, thunderstorm wind and tornadoes across the US on this storm day (45 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.
