Lake Charles, La. – Southwest Louisiana faces a multi-day flash flooding threat as a slow-moving storm system brings up to 10 inches of rain and severe thunderstorms beginning Tuesday afternoon.
According to the National Weather Service in Lake Charles, a Flood Watch is in effect through Thursday evening for much of western and central Louisiana, including Lafayette, Opelousas, and Alexandria. Rainfall totals between 4 to 8 inches are expected, with isolated pockets seeing as much as 10 inches. Thunderstorms capable of training over the same areas could lead to rapid water rises and dangerous flash flooding.
Lafayette and Jennings may see 6 to 8 inches of rain, while Lake Charles, De Ridder, and Alexandria could receive between 4 and 6 inches. Low-lying areas and those near waterways—like Pecan Island and Morgan City—should monitor for rapid rises. Roads prone to flooding, including sections of I-10 and US-190, could become impassable.
A Slight Risk for severe storms on Tuesday also includes damaging winds over 58 mph, one-inch hail, and a low tornado threat from Port Arthur to Leesville. Residents should charge devices, secure outdoor items, and have multiple ways to receive alerts.
Flash flood warnings may be issued quickly. Weather updates and a live briefing are expected from NWS Lake Charles at 7:30 a.m. Tuesday.
