Where: Vanderburgh County, Evansville
Property damage: $20,000
Reported by: NEWSPAPER
Coordinates: 38.025, -87.586 (the zone’s center; the record gives no point)

A band of slow-moving thunderstorms produced heavy rain as it sagged south across southwest Indiana. A particularly strong thunderstorm intensified to severe levels as it passed right over Evansville. Dime size hail and copious rainfall amounts between 2 and 4 inches per hour occurred downtown. Serious street flooding took place, with numerous stranded vehicles. Emergency services personnel performed many water rescues due to submerged vehicles. A restaurant was surrounded by water, trapping about 25 people inside the building until the water receded. A school on the north side of Evansville was closed after water came pouring into the building through doors and drains. The 265 students in the school were moved to a church on higher ground.

What these are

Flash Flood: Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.

After NWS Directive 10-1605, the rules offices file Storm Data by.
