Damage, injuries and deaths
National Weather Service offices recorded about $1.3 million in property damage and $517,000 in crop damage from hail, thunderstorm wind and tornadoes across the US on this storm day (39 events in 9 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.
