NEW ORLEANS — Severe flooding threats persisted across parts of the southern United States on Friday as the remnants of Tropical Storm Arthur and a broader pattern of slow-moving storms brought heavy rainfall, prompting flood warnings, emergency preparations and concerns about additional flash flooding from Texas to the Southeast, according to U.S. weather authorities.
The National Hurricane Center said Arthur weakened after making landfall along the upper Texas coast earlier this week, but officials warned that the system continued to produce dangerous rainfall capable of causing life-threatening flooding. Forecasts called for several inches of rain across portions of Louisiana, Mississippi, Alabama, Georgia and the Florida Panhandle through the end of the week. Authorities said localized areas could receive substantially higher amounts.
Emergency management agencies in several Gulf Coast states distributed sandbags, cleared drainage systems and urged residents in flood-prone areas to prepare for rapidly rising water. Local officials reported flooded roadways and isolated water rescues in parts of Texas and Louisiana following periods of intense rainfall.
“The primary hazard remains heavy rainfall and flash flooding,” the National Hurricane Center said in a public advisory issued after the storm weakened. The agency warned that flooding risks could continue even as the system lost tropical characteristics.
The flooding threat follows a broader pattern of unsettled weather that has affected parts of the South throughout June. Meteorologists said abundant Gulf moisture and repeated rounds of thunderstorms have increased the risk of flash flooding across areas already saturated by earlier rainfall. Weather forecasters also warned that additional storms could develop as moisture spreads farther east across the Southeast.
In Texas, local National Weather Service offices warned that rainfall rates could exceed several inches per hour in some locations, raising the risk of flash flooding in urban areas, along creeks and near low-lying roads. Authorities urged motorists to avoid driving through flooded areas and advised residents to monitor emergency alerts.
State and local agencies reported scattered power outages and transportation disruptions linked to the storms. Officials said assessments of property damage were continuing, though comprehensive figures were not immediately available. Reports of injuries and rescues varied by jurisdiction, and details remained unclear in several areas.
The current weather system marks the first named storm of the 2026 Atlantic hurricane season. While forecasters said Arthur was expected to continue weakening, they cautioned that its remaining moisture could still generate heavy rain and thunderstorms across portions of the Southeast.
As of Friday evening, flood watches and warnings remained in effect in several southern states. Weather officials said the risk of flash flooding would continue through the weekend in some areas, with emergency agencies maintaining a heightened state of readiness as additional storms move through the region.
