Huge System to Bring Dousing Rain and Severe Threat to the Deep South
A potent upper-level low, combined with a surface low in the Gulf of Mexico, will continue to track eastward through late Saturday. This will lead to isolated thunderstorms and heavy rainfall that could produce localized flooding or flash flooding. Thursday there is a general risk for thunderstorms from the Storm Prediction Center that stretches from San Antonio, Texas to Mobile, Ala. (see graphic below). Rainfall amounts ,through midnight, will range from one to three inches. The heaviest rain will fall along the Gulf Coast — from Houston, Texas to New Orleans, La.
Friday, the area of low pressure will continue to track along the Gulf Coast and bring the potential for moderate to heavy rain from Mobile, Ala. to Wilmington, N.C. In addition the the rain, the Storm Prediction Center in Norman, Okla. has issued a “marginal” risk for severe weather — across parts of northern Florida, southern Georgia and coastal regions of the Carolinas — on Friday. The main threat in this area will be damaging wind gusts, but an isolated tornado can’t be ruled out in the vicinity of the surface low pressure. The heaviest rain will affect large sections of the Florida Panhandle to southern Georgia. Again, watch for localized flooding in these areas.
This low will continue to track up the East Coast and intensify, possibly becoming a nor’easter. Stay with Weather Nation for the very latest on this ever-changing forecast.
