San Antonio rolled into Wednesday, July 15, warm, muggy and on edge, with a lingering threat of heavy thunderstorms and a Flood Watch locked in through Thursday evening. Morning temperatures sat in the mid-70s, with an expected high near 82°F, but it is not the heat that has forecasters worried. A parade of slow-moving storms has set the stage for sudden, intense downpours across much of the city.
Flood Watch Through Thursday
The Flood Watch, first issued July 14, remains in effect through Thursday evening, July 16, for Bexar County and a large stretch of south-central Texas. The National Weather Service is warning about a serious flash-flood threat, with many spots projected to see 2–6 inches of rain and isolated areas possibly getting 10–20 inches. The corridor along U.S. 90 west of San Antonio faces the highest risk. Forecasters are calling for a high chance of showers and thunderstorms today, with 1–2 inches of rain possible in some locations. A few of the slower storms could also spin up brief tornadoes and bring gusty winds, according to NWS Austin/San Antonio.
Timing And What To Expect
Showers and thunderstorms are expected to hang around through the afternoon on Wednesday, July 15, leading to soggy commutes and periods of low visibility on local roads. From Wednesday night into Thursday, July 15–16, storms are expected to redevelop and drop more heavy rain. Many neighborhoods could receive a half inch to three quarters of an inch overnight, with pockets of higher totals where storms linger. East-southeast winds should stay near 5–10 mph, but stronger gusts are possible Thursday night as storms become more organized.
Safety And Local Resources
Residents in low-lying areas, near creeks, or along streets that are notorious for flooding should be ready to head to higher ground and avoid driving through high water. Officials urge people to sign up for alerts and pay attention to local instructions. For steps to take and how to get notifications, check out Bexar County wet‑weather safety. Keep more than one way to receive warnings and try to limit travel while the Flood Watch remains in effect.
