Texas and Gulf Coast face heightened flash‑flood risk from multi‑day heavy rain

A multi‑day heavy‑rain pattern is sweeping the Southern United States, putting large parts of Texas under moderate flash‑flood risk. The Weather Prediction Center placed the Edwards Plateau, Hill Country and Rio Grande Plains in a Level 3 (out of 4) moderate risk zone, with isolated totals of up to eight inches possible from repeated thunderstorms through Thursday. Communities such as Del Rio, Eagle Pass, Uvalde, San Antonio and Austin were warned that rapid street flooding, low‑water crossing inundation and swift creek rises could occur.

In nearby Houston, deeper Gulf moisture is sustaining scattered showers and thunderstorms, raising the chance of street‑level flooding on Monday. The National Weather Service noted a 2‑out‑of‑4 risk of street flooding for the city, with similar concerns extending to the broader Houston metropolitan area.

Further east, south‑central Louisiana is seeing a stalled frontal boundary and abundant tropical moisture that could produce several inches of rain and localized flash flooding, especially around Baton Rouge. Meanwhile, the Alabama Gulf Coast is under a marginal severe‑weather risk as scattered storms move through the region, adding to the broader storm‑track that is affecting the Gulf states.

Authorities in the affected areas have urged residents to monitor warnings, avoid flooded roadways and be prepared for rapid changes in conditions as storms repeatedly move over the same locations.
