More rain expected this evening and this weekend has all of north Georgia including metro Atlanta and Athens under a flash flood watch effective 4 p.m. today until early Sunday morning.

Meteorologists at the National Weather Service in Peachtree City predict rain and thunderstorms will be moving through the state over night and Saturday, which puts Georgia at risk for more flooding.

"Unfortunately, we've had to put north Georgia into flash flood watch because of this potential of one to two inches of rain and could have isolated higher amounts possible," said Weather Service hydrologist Kent Frantz, "which could cause additional flooding, either in areas that have already had flooding and new areas in the urbanized metro area and up in the north Georgia mountains."

Frantz says the rain may move through slowly at first, and the greatest chance of heavy rain is Saturday.

Meanwhile, the Army Corps of Engineers has a close watch on Lake Allatoona, just north of metro Atlanta and West Point Lake near Columbus because both lakes are already well above full pool.
