Central Texas is anticipating its first substantial storms of the season after a prolonged period of dry weather. Austin and surrounding areas are on alert for severe thunderstorms and the possibility of flooding this upcoming weekend, according to reports from the Austin American-Statesman.
A storm system moving into the southern Rockies on Friday, October 24, is set to enhance southerly winds across Central Texas. This will draw more moisture from the Gulf of Mexico, and when combined with an incoming Pacific cold front, it’s expected to create unstable atmospheric conditions conducive to severe thunderstorms. Federal weather agencies, including the National Weather Service, predict that these conditions could lead to two rounds of heavy rainfall across the state.
Severe Weather Risk in Austin
The Storm Prediction Center has designated a Level 2 out of 5 risk for severe weather impacting areas from Big Bend National Park to the Texas-Oklahoma border. This alert specifically includes the Austin metropolitan area and the scenic Texas Hill Country.
Residents are advised to prepare for intense storms that may bring damaging winds, hail, and even the potential for tornadoes. An initial line of storms is forecast to sweep across West Texas and reach Austin by early Saturday morning, around 2 a.m., with heavy rain potentially persisting until 8 a.m. Saturday.
Rainfall and Flash Flood Concerns
Austin could experience up to 3 inches of rain from the first wave of storms. The Edwards Plateau, Hill Country, and the Interstate 35 corridor are particularly at risk for excessive rainfall, with a Level 2 out of 4 risk identified. Flash flooding is a significant concern in urban areas with inadequate drainage, as well as near small streams and low-water crossings.
Second Storm System Expected
Following a brief respite on Saturday morning, a second round of storms is anticipated for Saturday afternoon. While this system may bring moderate to heavy rain, the risk of severe weather is lower, rated at Level 1 out of 5. Temperatures are expected to be slightly cooler, with daytime highs in the low 80s.
Safety During Flash Floods
With much of the rainfall expected overnight, road safety is a primary concern. Flooded roads can be difficult to spot in the dark, and even a foot of moving water is powerful enough to carry away a vehicle. It is crucial for drivers to never attempt to cross barricaded roads and to seek alternative routes. For real-time road condition updates, residents can consult the ATX Floods website.
