It was clear and about 70°F at 4:50 a.m. CDT on Saturday, May 23, 2026, in Austin, but the calm start is misleading. The National Weather Service has a Flood Watch in effect through Monday evening, and the holiday weekend is shaping up to be a soggy one. Forecasters expect multiple rounds of showers and thunderstorms, with pockets of heavy rain that could trigger localized flash flooding, especially in low‑lying spots.
Today and the weekend
Showers and storms are likely on Saturday, with a high near 86°F and the best shot at thunderstorms during the afternoon and evening. Temperatures slip into the low 70s overnight and stay muggy, and more rounds of storms are possible Sunday and into Memorial Day. Any brief but intense cell could dump a quarter to a half‑inch of rain in short order, with higher local totals if storms repeatedly track over the same neighborhoods.
Flood watch and risks
The Flood Watch runs through 7:00 p.m. CDT Monday, May 25, 2026, and calls for 1 to 3 inches of rain across much of the area during the watch period, with isolated amounts up to 6 inches, enough to produce life‑threatening flooding in some locations. Creeks, streams and low‑water crossings may rise quickly, and the NWS warns that excessive runoff could flood roads and other low‑lying spots. These details and the extended outlook come from the National Weather Service Austin/San Antonio.
Commute and local impacts
Drivers should plan on slick roads and slower commutes during and after heavier downpours, and build in extra time to get around. Avoid low‑water crossings, since they can flood with very little warning, and be wary of standing water that can hide road damage. Public transit riders should watch for service alerts and expect possible delays, particularly on Saturday afternoon and into the holiday.
How to stay safe
If you live in a flood‑prone spot, move valuables to higher ground and have a simple plan for where you will shelter safely. Never drive through flooded roadways; six inches of moving water can knock a person off their feet and sweep a car away, and you will not know how deep it is from behind the wheel. Keep phones charged so you can receive local warnings, consider postponing nonessential outdoor plans when the rain is at its worst, and check official updates before heading out.
