Isaac Did Little To Relieve Drought

It’s been a wet period across Georgia, thanks in part to the outer reaches of Tropical Storm Isaac. But that's done little to relieve the region's drought.

"Unfortunately the tropical storm did not come in the optimal path for getting rid of drought in Georgia,” says State Agricultural Climatologist Pam Knox.

Knox says what rain Isaac did drop on Georgia may have been too little, too fast.

"To get rid of the drought it’s going to take several inches of sustained rains," she said. "If the several inches all comes in one hour, then of course it’s all going to run off and it’s not going help very much."

Even though some areas of the state did see sustained rains of 1 or 2 inches, Knox says that doesn't count for much during the warm months.

“In the summer you need to have really at least an inch a week just to keep up with evaporation,” she said.

On the bright side Knox says an El Nino weather pattern is definitely shaping up in the Pacific, which generally means a cool, wet winter for Georgia.

But in terms of immediate relief? Look to the Atlantic for another storm, Knox says.
