Property damage: $5,000

Heavy rains, from slow moving thunderstorms, caused water to cover many roads in the north part of the county. Radar estimated that eight to ten inches of rainfall fell across the north part of the county. Rainfall of 7.5 inches was reported in a gage near Blackman. Many roads, especially secondary dirt roads, had to be closed for several hours until the high water receded.

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.
