Flash Flood, Marion

When: July 16, 7:15 PM EST to 9:15 PM EST
Where: Marion County, Indianapolis
Reported by: LAW ENFORCEMENT
Coordinates: 39.783, -86.150

Roads were barricaded due to high water at several locations throughout the city. A widely publicized photo appeared in the Indianapolis Star the next day of several cars stuck in five feet of water in the Lafayette Square Mall parking lot. Heavy rain of 2 to possibly more than 4 inches was produced by nearly stationary thunderstorms which formed in the very moist airmass left behind by the remnants of Hurricane Dennis. Other parking lots and viaducts were flooded, and several minor traffic accidents were attributed to the heavy rainfall. 1,600 electricity customers throughout the city lost power at least briefly due in part to the flooding and the accidents.

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.
