* Flash Flood Warning for...
Northeastern Murray County in northwestern Georgia...
Gilmer County in north central Georgia...
Central Fannin County in north central Georgia...
* Until 1045 AM EDT Saturday.
* At 439 AM EDT, Doppler radar indicated thunderstorms producing
heavy rain across the warned area. Two to three inches of rain
have fallen and an additional one to two inches are expected.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, country roads, farmland, and other low lying
