NEW ORLEANS — Severe flooding threatened several Southern U.S. states on Saturday, prompting evacuations in some communities as officials warned that heavy rainfall linked to the remnants of Tropical Storm Arthur continued to inundate parts of the Gulf Coast and Deep South.
Emergency management agencies and the National Weather Service warned that life-threatening flash flooding remained possible across portions of Louisiana, Mississippi, Alabama and neighboring states after days of intense rainfall. Flood watches and flash flood emergencies were issued in several areas, while local authorities urged residents in vulnerable locations to move to higher ground or follow evacuation orders where issued.
The flooding threat followed the formation and landfall of Tropical Storm Arthur earlier in the week. Although the storm weakened after coming ashore along the Texas coast, forecasters said its remnants continued to draw large amounts of tropical moisture across the region, producing repeated rounds of heavy rain and thunderstorms.
The National Weather Service issued high-level flood outlooks for parts of the central Gulf Coast, according to weather reports and forecasts published this week. Rainfall rates of several inches per hour were reported in some locations, increasing the risk of flash flooding in urban areas and along rivers and streams. Authorities also warned of possible road closures, water rescues and disruptions to transportation networks.
State and local officials activated emergency response measures, including the deployment of rescue personnel and the opening of shelters in some affected areas. In Louisiana and Mississippi, officials had earlier distributed sandbags and prepared drainage systems ahead of the heaviest rainfall.
“We urge residents not to drive through flooded roadways and to follow instructions from local emergency officials,” emergency authorities said in public advisories issued during the flooding threat.
Forecasters said the greatest concern remained flash flooding rather than wind damage, as the former tropical system continued moving eastward. Some areas had already received several inches of rain, with additional precipitation forecast through the weekend. Weather officials also warned that isolated tornadoes could not be ruled out in parts of the Southeast.
As of Saturday, flood watches and emergency alerts remained in effect across portions of the Gulf Coast and Southeast. Officials said response operations were continuing, while the full extent of damage and any additional evacuations remained unclear.
