A weather graphic titled "Locally Heavy Rain Expected," from NWS Houston/Galveston, updated Saturday, July 26, 2025, 3:26 AM. It warns of tropical moisture causing scattered showers and thunderstorms today and Saturday, with locally heavy rainfall possible (1-2 inches per hour). An "Areawide Marginal Risk (level 1 of 4) of Excessive Rainfall" is capable of flash flooding today. Timing indicates showers along the coast this morning, spreading inland. Impacts include minor flooding of low-lying/poor drainage areas and a few instances of flash flooding, especially in areas with recent heavy rain. Actions advise remaining weather-aware and not driving through flooded roadways. An "Excessive Rainfall Outlook" map shows areas with a Flash Flood Risk of 1 (Marginal), covering much of Southeast Texas including Houston, Galveston, and College Station.

A five-day weather forecast for the Houston area (July 26-30, 2025), indicating scattered showers with locally heavy rainfall, a brief cool down, and the return of triple-digit heat indices by Sunday.

Never, never, never leave children, disabled or elderly adults, or pets in parked, unattended vehicles! Studies have shown that the temperature inside a parked vehicle can rapidly rise to dangerous levels for people and pets. Leaving the windows slightly open does not significantly decrease the heating rate. The effects can be more severe on children because their bodies have not developed the ability to efficiently regulate internal temperature.

¡Nunca, nunca, nunca deje a niños, discapacitados, personas mayores o mascotas en coches aparcados y sin atender! Estudios demuestran que la temperatura interior de un coche aparcado puede ascender rápidamente a niveles peligrosos para personas y animales. Dejar las ventanas entreabiertas no reduce significativamente el aumento de la temperatura. Los efectos pueden ser más graves en los niños porque aún no tienen la capacidad de regular su temperatura corporal de forma eficiente.
