Flood risk continues for Southeast as downpours unleash up to 2 inches of rain per hour

Much of the Southeast awaits another dose of heavy thunderstorms, which will heighten the flooding threat through the end of the week.

Repetitive downpours over the last few days have brought as much as 4 inches of rain to some places across the South.

As the pattern continues, not much change is in sight.

"A stalled frontal boundary across the Southeast will set the stage for a several-day stretch of heavy rainfall," according to AccuWeather Meteorologist Brett Rathbun.

This will hold in moisture streaming up from the Gulf of Mexico, with slow-moving thunderstorms over the Carolinas and into the southern Atlantic Coast.

"The large amount of moisture in the atmosphere will make it easy for storms to produce rainfall rates of 1 to 2 inches per hour," Rathbun said.

The greatest threat for the heaviest thunderstorms will be from central and eastern North Carolina to the Florida Panhandle and the Mississippi Gulf Coast.

Flash flooding will be most likely to occur in the areas where multiple storms fire up through the week.

As the front slowly sinks southward throughout the week, parts of North Carolina will start to return to the typical summertime pattern of spotty afternoon thunderstorms.

Despite the shrinking nature of the heavy downpours, travel could be impacted across the East.

"Those traveling along Interstate 95 from Benson, North Carolina, to Jacksonville, Florida, will want to slow down in downpours to reduce the risk of hydroplaning. Never drive through a flooded roadway," Rathbun said.

There could also be delays at air travel to any airport from Raleigh to Pensacola, which could have a cascading effect to other major airports across the country.

Spotty showers and thunderstorms will extend across the remainder of the Southeast, reaching parts of the Tennessee and Mississippi River valleys.

Due to their scattered nature, these thunderstorms will not be enough to help make up the deficit of rain so far this summer across parts of the Southeast.

Drought-stricken areas of northern Georgia and eastern Tennessee will need many days of steady rain to return to near normal.

The remainder of the Southeast will return to the typical afternoon and evening thunderstorms in time for the weekend.
