San Antonio Flood Warning: Weekend Showers Pose Risk of Flash Flooding

San Antonio residents are urged to remain vigilant this weekend as a weather system bringing heavy rainfall threatens to unleash flash flooding across the city. The National Weather Service (NWS) has issued a flood warning, advising residents to take precautions and stay informed about the evolving situation. The potential for significant rainfall, coupled with already saturated ground from recent showers, creates a heightened risk of dangerous flash flooding.

When is the rain expected?

The heaviest rainfall is predicted to hit San Antonio beginning Friday evening and continuing through Sunday. While the exact amount of rainfall remains uncertain, forecasts indicate the potential for several inches of accumulation within a short period. This rapid accumulation is the primary concern, as it can overwhelm drainage systems and lead to rapid rises in creeks and rivers.

What areas are most at risk?

While the entire San Antonio metropolitan area is under a flood watch, certain areas are considered particularly vulnerable. These include low-lying regions, areas near creeks and rivers like the San Antonio Riverwalk, and neighborhoods with a history of flooding. Residents in these high-risk zones should be especially prepared for potential flooding and take proactive measures to protect their property.

How to stay safe during a flood:

• Stay informed: Continuously monitor weather reports from trusted sources like the National Weather Service (NWS) and local news channels. Sign up for emergency alerts from the city of San Antonio.
• Avoid flooded areas: Never attempt to drive or walk through flooded areas. The depth of water can be deceptive, and even a few inches of fast-moving water can sweep a vehicle away.
• Move valuables to higher ground: Relocate important documents, electronics, and other valuable items to upper floors or higher ground to minimize potential damage.
• Have an evacuation plan: If you live in a flood-prone area, prepare an evacuation plan and identify a safe location to go in case of flooding.
• Know your evacuation route: Familiarize yourself with your designated evacuation route and know where the nearest emergency shelter is located.

What is the city doing?

The City of San Antonio is actively monitoring the situation and has mobilized its emergency response teams. Crews are clearing drainage systems and preparing for potential flood-related incidents. City officials urge residents to cooperate with emergency personnel and follow all instructions issued during the event.

What to do after the flood:

Following the storm, be aware of potential hazards such as downed power lines and contaminated water. Report any damage to your property to your insurance company and local authorities. Learn more about flood safety and recovery resources on the .

Remember, when it comes to flooding, your safety is the top priority. Don't underestimate the power of water. Stay safe, San Antonio!
