Austin, Texas – Triple-digit heat returns to Central Texas Sunday, with afternoon highs climbing from the lower 90s up to 105 degrees, making outdoor activities dangerous and increasing the risk of heat-related illness. According to the National Weather Service, much of the region—including Austin, San Antonio, and the Hill Country—will face mostly sunny skies, intense sunshine, and little relief from the heat until at least Sunday evening.
Northeastern counties such as Georgetown, Llano, and parts of the I-35 corridor should stay alert for isolated thunderstorms late Sunday night. Some storms could bring locally heavy rain, causing minor flooding in low-lying spots and areas with poor drainage. While the risk for widespread severe weather remains low, pockets of intense downpours may disrupt travel or outdoor events overnight.
Residents are urged to limit time outdoors during peak heat, stay hydrated, and check on vulnerable neighbors or pets. If storms develop Sunday night, motorists should never drive across flooded roads. Temperatures will stay hot through midweek, with only brief, spotty rain chances north of San Antonio and Austin.
Heat advisories and storm watches may be updated as conditions evolve. Stay tuned for the latest alerts from the National Weather Service.
