What happened
The episode as NWS FFC wrote it up.
The Forsyth County Emergency Management Director reported that persistent thunderstorms had dumped 3-4 inches of rain across much of the county during the afternoon. The heavy rain resulted in runoff that caused Dick Creek near the intersection of Mathis Airport Road and Bagley Road to exceed its banks and flood the roads. A sheriff's deputy vehicle became submerged in the flood waters and was destroyed. In addition, three to five homes in the area were flooded as a result of the debris which blocked storm drains in the area. Only minor damage was reported to the homes.A trained storm spotter reported that several hours of heavy rainfall had resulted in widespread street flooding across much of northern Gilmer county.
