As light rain continues, heavier waves of rain are forming on the edges of metro Atlanta, Channel 2 Action News reported. 

The showers made the evening commute a mess, and the heavy rain should only make slick roads wetter and put many areas at risk of flooding.

“Heavy rain will start to pick up ... through this evening and into the overnight hours,” Channel 2 meteorologist Karen Minton said. “We could pick up an additional 2 to 3 inches of rain, and when you combine that with saturated soil and the amounts we've already had, flooding is a possibility in many areas. You have got to be weather aware.”

 

The most rain will fall from the I-85 corridor eastward, Channel 2 meteorologist Brian Monahan said. Over west Georgia, rainfall amounts are expected to be an inch or less. 

All of North Georgia and much of central Georgia is under a flash flood watch until 7 a.m. Thursday, meaning the conditions could develop to produce flash flooding.

“Due to the heavy rainfall the past several days, many creeks and streams are already near or above bankfull,” the National Weather Service said in an advisory. “Creeks and rivers could rise out of their banks, closing roads and impacting homes, businesses and farms. High water may not recede until well after the rain has ended.”

 

A flood warning continues for Big Creek near Alpharetta, and Suwanee Creek near Suwanee. Since Monday afternoon, those areas have seen minor flooding onto green spaces, sidewalks and roadways as the creeks have risen past flood stage and overrun. 

The latest projections show the heaviest rain falling until 11 p.m. By 10 p.m., strong rain showers will still be over the Athens and Eatonton areas, then Minton said it will start to move out.

“With clouds and rain in the forecast, temperatures will continue to run well below average — mainly in the 40s across North Georgia today and tomorrow,” Monahan said. 

 

North Georgia should see more showers early Thursday morning before it all dries out in the afternoon, according to the latest forecast from Channel 2.

In the North Georgia mountains, a few snow flurries or light snow showers are possible Thursday as the last of the moisture squeezes out of the state and colder air moves in, according to Channel 2.

“It’s going to be chilly on Friday morning, but sunny and dry through the weekend,” Minton said.
