Weekend Rain Threat: San Antonio Facing Potential Flash Flooding

San Antonio residents are bracing for a potentially dangerous weekend, as forecasters predict heavy rainfall that could lead to flash flooding across the city. The National Weather Service has issued a flash flood watch, urging residents to prepare for the possibility of significant rainfall accumulation and dangerous conditions. This comes after weeks of dry weather, leaving the ground parched and less able to absorb heavy downpours.

Timing and Intensity of the Storm:

The heaviest rainfall is expected to begin late Friday evening and continue through Saturday. The National Weather Service predicts rainfall totals could reach 3 to 5 inches in many areas, with isolated locations potentially seeing even higher amounts. This level of precipitation in a short period significantly increases the risk of flash flooding, especially in low-lying areas and near creeks and rivers. The San Antonio River Authority (SARA) is closely monitoring water levels and preparing for potential flooding events.

Areas Most at Risk:

While the entire city is under a flash flood watch, certain areas are considered more vulnerable. These include:

• Low-lying neighborhoods: Residents in areas known for poor drainage should take extra precautions.
• Areas near creeks and rivers: The risk of rapid water rises is significantly higher near waterways.
• Areas with a history of flooding: Past flood events indicate potential problem areas. Check local news and government websites for specific locations.

How to Prepare for Flash Flooding:

The best way to stay safe is to be prepared. Here's what you can do:

• Monitor weather forecasts: Stay updated on the latest predictions from the National Weather Service and local news.
• Clear drains and gutters: Ensure water can flow freely away from your property.
• Move valuable items to higher ground: Protect important possessions from potential water damage.
• Know your evacuation routes: Familiarize yourself with escape routes in case flooding becomes severe.
• Sign up for emergency alerts: Receive timely warnings and updates from local authorities. You can usually do this through your city's website or emergency management agency.
• Have an emergency kit ready: Include essentials such as water, non-perishable food, flashlights, and a first-aid kit.

What to Do During a Flash Flood:

If you encounter flash flooding:

• Never drive through flooded areas: Even a few inches of water can sweep a vehicle away. Turn around, don't drown.
• Avoid walking or hiking in floodwaters: The water may be contaminated or contain hidden dangers.
• Seek higher ground immediately: Move to a safe location away from floodwaters.
• Contact emergency services if needed: Call 911 if you or someone you know is in immediate danger.
