San Antonio — City officials and emergency agencies are preparing for heavy rainfall and the possibility of flash flooding as storms approach this weekend. Severe Thunderstorm Watch remains in effect until 3 AM Saturday, with a Flood Watch until 1 PM Saturday. State, county and city teams are mobilizing resources and coordinating outreach to protect vulnerable residents and maintain critical services.

Immediate situation and alerts

State and local officials are closely monitoring weather conditions and are ready to respond as necessary. Meteorological updates forecast a mix of rain and sun with scattered thunderstorms likely through the weekend. Emergency managers have issued watches to alert the public to the potential for rapidly changing conditions and localized flooding.

Preparedness and response actions

Local businesses and non-profits, including the Haven for Hope and the Texas Division of Emergency Management (TDEM), are preparing for incoming storms this weekend. TDEM is mobilizing resources including helicopters and swift water rescue teams, ready for deployment in response to flooding. TDEM confirms they have resources on standby and urge residents to stay informed and safe as weather conditions evolve.

Haven for Hope plans to have outreach teams on the ground to inform homeless populations about the storms. Terrell and Kimara King, owners of ‘Momma Luvs Soul Food & Caribbean’, shared their personal experiences of the previous flooding, expressing concern for the safety of vulnerable populations, including homeless individuals, during the storms. Local organizations and shelter providers are coordinating messaging and logistics to assist people who may have limited options for safety and shelter.

TDEM’s Media and Communications Chief, Wes Rapaport, emphasizes the importance of public awareness regarding road conditions during possible flooding. Local officials are urging drivers to avoid flooded roadways and to follow guidance from authorities on closures and detours.

Resources and operational readiness

Emergency resources being staged include personnel trained in swift water rescue, aviation assets for search and rescue and transport, and coordinated ground teams for outreach and damage assessment. State and local emergency operations centers are in increased readiness posture to track incidents and deploy assets where needed.

Community concerns and past impacts

The community remains sensitive to the risk of flooding due to a major event this past summer. The June 12 floods, which killed 13 people, saw over 6.3 inches of rain in a single day, representing a historical weather event for San Antonio. That event caused loss of life, property damage and demonstrated vulnerabilities in infrastructure and response systems.

Previous flooding incidents have highlighted the need for improved infrastructure and emergency response preparedness in the region. City officials are calling for equitable infrastructure investments to better address flood prevention and safety measures. Council members emphasize that infrastructure should be prioritized over new projects as the community prepares for future storm challenges.
