As I’m writing this at 2:45p CDT, there’s a few scattered storms across our region, with the area bounded by Tuscaloosa, Birmingham, and Montgomery seeing the most storm activity. If you look south of Louisiana, you’ll see tropical storm Arthur, which became the first named storm of the 2026 Atlantic hurricane season this morning.
While the center of tropical storm Arthur is currently over land near Bay City, TX, the heaviest rain bands of the storm are situated over the gulf and will move northeast into southeastern Louisiana later tonight. By the overnight and early morning hours, the heaviest rain bands will have moved into southern Mississippi. By tomorrow afternoon, the storm will have moved into Alabama.
A widespread 2-4″ of rain is expected from tropical storm Arthur between Lafayette and Montgomery from now until Friday morning, with some localized areas likely to see totals much higher than that. The area most likely to see more than that is the area bounded by Jackson, McComb, and Hattiesburg. Flash flooding is highly likely tonight and tomorrow. If you are driving and see a flooded road, turn around and don’t drown!
