Up to 4 inches of rain is expected to fall over parts of the Deep South through tonight as a moisture-laden storm system takes shape. The excessive amount of rain from storms could lead to flooding in some areas, while other storms could turn severe to start the workweek. A potent combination of strong atmospheric energy approaching from the west and rich moisture flowing off the Gulf of Mexico will be the impetus for explosive thunderstorm development. Tropical downpours with rain falling at the rate of more than an inch an hour can be expected at times through tonight from the central Gulf Coast north into the Tennessee Valley and southern Appalachians.
The end result in many areas early on Tuesday will be 2 to 4 inches of rain, falling fast enough to cause street and low-lying flooding problems. In addition, the strengthening storm system could turn some of the thunderstorms severe with an enhanced threat for damaging wind gusts and even isolated tornadoes expected later today into tonight. A portion of Mississippi, Alabama, the Florida Panhandle and Georgia will be at risk for these dangerous storms, which could last beyond sunset.
While a widespread severe weather outbreak is not expected, anytime tornadoes are possible the public should stay alert and keep up to date with the changing weather. The threat for severe weather will expand to the north and east into Tuesday, reaching the I-95 corridor from the Carolinas all the way to the Northeast.
