KEY POINTS

  • The NWS is expecting a 'very wet weather pattern' in the southern U.S. over the next few days
  • Parts of southeastern North Carolina are at risk of flash flooding
  • Texas accounts for most of the flood warnings issued by the NWS

Heavy rainfall and flood events across the Southern United States have prompted flood-related weather warnings and alerts in several states. The National Weather Service (NWS) has projected further heavy rain to continue across the south through Wednesday.

In its Monday report about weather events in the U.S., the NWS said a "very wet weather pattern will continue across portions of the southern U.S. from east Texas into the Lower Mississippi Valley over the next few days." The agency said potential flooding is "likely from northern Louisiana into west-central Mississippi" on Tuesday. The NWS warned of heavy rain and flash flooding threats may last through Wednesday.

The Weather Prediction Center (WPC) in Center College Park, Maryland, projected the risk of flash flooding in South-central to Southeastern North Carolina on Tuesday, adding that rain totaling 3-4 inches is likely.

The Maryland WPC office also warned of potential flash flooding in South-central Texas on Tuesday due to heavy rainfall in the area.

The NWS previously warned of up to seven inches of rain affecting northern Texas. The agency said that while the heavy rainfall is welcomed due to the ongoing drought affecting the U.S. and other western nations, "the potential still exists for instances of flash flooding in urban areas and places with poor drainage."
