Summary
A rare Level 4-of-4 flash-flood risk was issued Thursday for the Mississippi and Alabama coasts as Arthur’s remnants spread life-threatening flooding across the South.
Rain totals of 5 to 8 inches are forecast from southern Texas to Alabama, with 8 to 12 inches possible in parts of Louisiana as Pacific and Gulf moisture feed the storm’s eastern side.
Flood watches cover most of Louisiana, Mississippi, Alabama and Georgia, with cities including Biloxi, Mobile, Baton Rouge, Jackson, Montgomery and Atlanta in the danger zone.
Texas has already recorded one death — a 15-year-old who drowned in a flooded pond — while coastal Mississippi and southern Alabama also face a Level 2-of-5 tornado threat.
The rain is expected to push into the Carolinas through Friday, and a new low could form off the East Coast over the Gulf Stream, bringing more gusty winds and heavy rain.

Overview
Tropical Storm Arthur, the first named storm of the 2026 Atlantic season, quickly weakened into a low-pressure area and was downgraded to a post-tropical cyclone, leading to the end of all storm watches and warnings. However, its remnants still pose a serious threat, fueling a prolonged period of heavy rain and dangerous, life-threatening flash flooding across the Gulf Coast and southeastern United States. While Arthur is expected to dissipate soon, forecasters are monitoring the possibility of new low-pressure development from its leftover energy, highlighting the ongoing risks and the need for continued vigilance in affected regions.
