A lingering frontal boundary, which was responsible for shielding the Eastern Seaboard from a direct hit by Hurricane Erin, has now turned its attention to the Southeast. The front is bringing with it heavy rain and dangerous flash flooding across the South. Charleston, SC, was among the hardest hit with the rainfall on Friday, with 4.16” of rain falling which led to flooding. 

Looking ahead, the greatest risk of flash flooding this weekend remains concentrated from Charleston into southeastern Georgia, including Northeastern Florida. The Weather Prediction Center has issued a Slight Risk ( level 2 out of 4) flash flood risk for this area, while Flood Watches remain in effect. 

Storms will stick around Saturday, with rainfall rates of 2–3 inches per hour possible in heavier, slower-moving systems. Some areas may accumulate 3–5 inches of rain by day’s end.

Showers and thunderstorms will stick around through the rest of the weekend. Starting relatively early each morning. The front will slowly make its way farther to the South and bring heavy rainfall across Central Florida.

The Georgia Coast is expected to see anywhere between an additional 1-2 inches, with isolated higher amounts possible. Soils in this region are saturated from 1-3" of rainfall along the stationary front since Friday. An additional 1-3" is possible with isolated totals even higher.

Tune into the Eastern regional forecast :10 past the hour for more details.
