Atlanta, GA – Rivers across parts of the southeastern United States are rising Sunday, October 11, after heavy rainfall associated with Isaías dumped more than 9 inches of rain in some locations, raising concerns about flooding across several states.
According to the National Weather Service Southeast River Forecast Center, widespread rainfall has triggered numerous river rises to action stage and flood stage across portions of the central and eastern Gulf Coast regions.
Some of the most concerning conditions are developing in Florida and South Carolina , where isolated moderate river flooding has been observed or is forecast.
Meanwhile, scattered rivers across Georgia and the inland Carolinas are reaching or expected to reach action stage, indicating elevated water levels that require monitoring.
Rainfall estimates covering the 72 hour period ending Sunday morning show extensive precipitation stretching from the Gulf Coast into the Carolinas.
Some locations received more than 9 inches of rain, although rainfall totals varied significantly across the Southeast.
The flooding threat may continue even after the heaviest rainfall ends.
River levels can remain elevated or continue rising as runoff from saturated areas moves downstream, potentially creating additional problems for low lying communities and areas near waterways.
Residents in affected areas should pay particular attention to river forecasts, especially where roads, bridges and neighborhoods are vulnerable to rising water.
Drivers should avoid flooded roadways and never attempt to cross moving water, even when the depth appears manageable.
The National Weather Service distinguishes between action stage, when water levels warrant closer monitoring, and flood stage, when flooding begins affecting designated areas.
Not every river experiencing elevated levels is expected to flood.
As the region continues dealing with the aftermath of Isaías, residents across Florida, Georgia and the Carolinas are encouraged to monitor local National Weather Service updates and river forecasts.
Additional river rises remain possible as water continues moving through affected watersheds.
