San Antonio rolled out of bed to that familiar combo of clouds, humidity and sweat-soaked T-shirts, with temperatures near 79°F and a high near 90°F on tap. A Flood Watch is still in place into midday Friday, and with the ground already saturated from recent drenchers, even quick downpours can turn streets and creeks into trouble spots in a hurry. If you can, keep morning plans flexible and steer clear of low-water crossings.
Flash Flood Threat This Morning
Forecasters are tracking yet another round of heavy rain that could move through overnight into Friday morning, with the biggest concern across the western Hill Country and areas just west of the city. According to NWS Austin/San Antonio, a broad swath of the region could see another 2–4 inches of rain, with isolated pockets up to 8 inches. Moderate to major river flooding is already ongoing across several basins, so if you live near creeks or low-water crossings, limit travel and be ready to move to higher ground if water starts rising.
Where Rain Will Be Heaviest
The bullseye for the heaviest downpours remains the western Hill Country, the southern Edwards Plateau and parts of the Rio Grande Plains. Areas that have already picked up 8–10 inches over the last 48 hours are especially primed for trouble. When soils are this soaked, even an extra half-inch to an inch of rain in an hour can trigger dangerous runoff and rapid rises. Residents near the Pedernales, Medina, Guadalupe, San Antonio or Nueces basins should keep tabs on local road closures and river gauges as the next round of storms rolls through.
Temperatures And Winds
Despite all the water, the heat is not tapping out. Today’s high should reach around 90°F, with south-southeast winds at 5–10 mph and gusts up to 25 mph making it feel both muggy and occasionally blustery. Saturday trends hotter, with highs in the low 90s and heat index values near 100°F in some spots. Water from the sky may be the main hazard right now, but remember to drink plenty of it too and check on neighbors who might struggle with the heat.
City Response And What To Do
City crews and emergency teams have been busy this week cleaning up from severe weather, and officials are asking residents to take the flood threat seriously and obey local alerts and barricades. The City of San Antonio reports that crews are assessing damage and responding to incidents across northwest Bexar County. Residents are urged to keep phones charged, map out an evacuation route if they live near rivers, and never drive through standing water. Turn Around, Don't Drown.
