City Continues to Monitor Storms and Flooding
Published on October 01, 2026
SAN ANTONIO (October 1, 2026) — The City of San Antonio continues to prepare for and respond to storms that will continue to move through South Central Texas through Friday and urges residents to continue to remain aware and prepared. Heavy rainfall can quickly lead to dangerous flooding across San Antonio.
A Flood Watch remains in effect through 7 p.m. Friday and a Flash Flood Warning remains in effect until 7 p.m. on Thursday. As of 3:30 p.m. today, between 1 and 4 inches of rain have fallen across the region and flash flooding has occurred, with 20 low-water crossings closed across Bexar County.
Residents should stay weather aware and avoid unnecessary travel during periods of heavy rain.
All City services and facilities including Libraries, Senior Centers, and Community Centers will continue to operate during normal operating hours on Friday. The City is ready to activate overnight shelters if the need arises.
What to Expect
According to the National Weather Service, widespread additional rainfall of 1-4 inches is expected, with isolated amounts up to 6 inches. The flooding threat is expected to diminish Friday as the front moves east, although rain chances will continue.
Stay Away from Flooded Areas
Flash flooding is possible where heavier rainfall develops.
Residents should:
- Move to higher ground immediately if you are near rising water. Do not wait.
- Never drive or walk through flooded roads.
- Never drive around barricades.
- If you must travel, check road conditions before leaving, avoid flood-prone areas and allow additional time.
- If a traffic signal is dark or flashing red, treat the intersection as an all-way stop.
- If you become trapped by rising water, call 911 and move to the highest safe point you can reach.

Teams have completed 317 site visits and posted 70 warning signs in low-lying areas. Outreach will continue Friday to check on individuals’ welfare.
Public Works is providing 24-hour coverage through Friday morning, pre-staging barricades at low-water crossings and monitoring tunnels, the High-Water Detection System, dam levels, traffic signals, and road conditions. Public Works currently reports 20 flashing warning lights, six posted road closures, and six traffic signals operating in flash mode.
San Antonio Police Department (SAPD) officers are monitoring major roadways and assisting TxDOT with active road closures. Officers will also report early Friday morning to support rush-hour traffic management and ongoing closures.

Development Services and Code Enforcement are prepared to coordinate damage assessments and respond to reports received through 311.
