Moisture and instability from the Gulf of Mexico has spawned thunderstorms that will impact the lower Mississippi Valley and parts of the southern U.S. through Wednesday, according to the National Weather Service. The 4 to 8 inches of rain forecasted could cause flash floods this week in Arkansas, Louisiana, and Texas, and the northwest Gulf coast into the mid-South.
Louisiana, Mississippi, Alabama and Tennessee are states expected to be hit the hardest by rain this week. Damaging thunderstorms along the Gulf Coast on Tuesday and Wednesday could cause wind gusts as high as 70 mph, AccuWeather said.
