Heavy Rainfall Expected to Cause River Flooding in Southeast U.S.

The National Weather Service (NWS) has issued warnings for potential river flooding across Mississippi, southern Alabama, southern Georgia, and the Florida Panhandle on Sunday, April 21, 2024. The flooding is expected to range from minor to moderate levels due to heavy rainfall in the affected regions.

According to the NWS, a storm system in the South will bring rounds of heavy rain and thunderstorms across parts of the Gulf Coast states, with the biggest threat for heavy downpours and flash flooding in central and eastern Texas, stretching into Mississippi. Total rainfall accumulations up to 3 inches are possible across much of the area from central Texas to central Mississippi, with up to 5 inches in some specific areas.

The NWS has also issued a Level 2 out of 4 flash flooding threat for East Texas, northern Louisiana, southern Arkansas, and western Mississippi, with widespread areas expected to receive 1-2 inches of rain and some spots reaching 3 inches through Sunday morning. Given the recent saturation from previous storms, flash flooding may occur.

Why this matters: The heavy rainfall and potential river flooding pose risks to residents in the affected areas, including property damage, road closures, and the need for possible evacuations. It is critical for individuals to stay informed about local weather conditions and follow the guidance of local authorities to ensure their safety.

Flood Warnings remain in effect for several rivers in the region, including the Pearl River near Bogalusa and the Pearl River near Pearl River, where minor flooding is forecast. The Pearl River near Bogalusa is expected to rise to a crest of 20.5 feet on Sunday evening, with woodlands and crop acreage along the river being flooded and the Bogue Chitto Wildlife Management area being inundated with water in recreational camps and over access roads.

The severe weather is part of a larger storm system that has brought scattered showers and thunderstorms to the South over the weekend. In addition to the heavy rainfall and flooding concerns, the threat also includes the possibility of strong wind gusts, hail, and a low chance of tornadoes.

Residents in the affected areas are advised to be prepared for the possibility of flooding and to take necessary precautions. The NWS warns motorists not to attempt to drive around barricades or through flooded areas and urges caution when walking near riverbanks. As the heavy rainfall is expected to impact the region on Saturday into Sunday morning, residents should closely monitor local weather conditions and follow the guidance of local authorities to ensure their safety.
