Flash Flood, Dewey

When: August 30, 10:30 AM CST to 1:00 PM CST
Where: Dewey County, 8 mi E of Camargo
Reported by: EMERGENCY MANAGER
Coordinates: 35.988, -99.008 (the zone’s center; the record gives no point)

A complex of thunderstorms moved southward through western Oklahoma during the morning of August 30, and dropped isolated heavy rainfall amounts up to 3 inches over western Dewey County near Camargo, OK. The runoff from this heavy precipitation produced flash flooding in the area during late morning and early afternoon of August 30. At 11:00 am CST, a Dewey County emergency management official reported that County Road EW67 was closed as a small creek had overflowed its banks and covered the road 8 miles east of Camargo, OK.

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.
