A flood watch is in effect through Wednesday morning, May 30, for much of metro Atlanta and North Georgia as the remains of Subtropical Storm Alberto pass over the Southeast.
Flood watches, like tornado watches and other advisories, mean “conditions may develop that lead to flash flooding,” according to the National Weather Service, but that no flash flooding has been reported yet.
There has been little storm damage in Hall County, according to Casey Ramsey, interim emergency management director for Hall County Fire Services. The area received about 1 inch of rain on Monday and was on track to get as much as 2 inches starting Tuesday morning, he said.
The storm made landfall over Alabama during the weekend. Between 1 and 3 inches of rainfall is expected over affected areas, which includes Hall County, as the storm continues its path north.
Local rainfall may be greater in some areas of North Georgia and West Georgia than the statewide report, including heavy rain in short periods of time, according to the National Weather Service.
Continue to check weather reports and monitor nearby creeks and rivers, which are already swollen and “will not take much additional rainfall to cause levels to rise above bankfull,” states the National Weather Service forecast.
The flood watch is in place until 8 a.m. Wednesday.
Rain is in the forecast through Friday for Hall County. Lake Lanier went into Memorial Day weekend almost a foot above full pool, and after several days of rain the lake now sits almost 1.5 feet above full pool.
The rain throughout the day on Tuesday pushed Lake Lanier to a five-year high for the end of May. The lake topped its 2013 level before the end of the work day, when water rose beyond 1,072.55 feet — putting it a few inches above the 2013 high.
The U.S. Army Corps of Engineers forecast calls for the lake to fall back to 1,071.1 feet by late June.
