Prepare for heavy rainfall with these best practices (Copyright 2024 by KSAT - All rights reserved.)

There are several ways to stay prepared when heavy rain events are in the forecast. Let’s dive into them below:

Check gutters and downspouts

  • Be sure that your gutters and downspouts around your home are clear of leaves and debris. If not, water may overflow and cause damage to the siding.
  • Fix sagging or loose gutters and make sure that downspouts are able to drain that water well away from your house.

Clear neighborhood storm drains of debris

  • Leaves, trash, and other items can clog up your neighborhood storm drains over time if not cleaned out.
  • When heavy rain is in the forecast, remove any debris from these storm drains beforehand to allow for accumulating water to properly drain.

Protect outdoor furniture, lawn items

  • Cover outdoor furniture and patio items with tarps to protect them from the rain.
  • Secure any loose lawn items and bring trash cans in closer to the house.

Keep up with tree maintenance

  • Some trees may have weakened due to the persistent drought conditions that we’ve seen in South Central Texas. If time allows, consider trimming limbs that may be damaged or rotting since some may snap or become easily uprooted in times of heavy rainfall.

Flood safety reminders

  • If flash flooding were to occur, move to higher ground when safe.
  • Do not attempt to drive through a flooded roadway, and remember the saying “Turn around, don’t drown.”
  • 6 inches of fast-moving flood water is enough to sweep a person off their feet; 12 inches of fast-moving flood water is enough to move cars off the road.
  • Stay away from areas that are prone to flooding (such as low-water crossings and poor drainage spots), and don’t drive around barricaded/blocked-off roadways. Here’s a list of a few areas around San Antonio that often see flooding issues when heavy rainfall occurs.
  • Avoid downed power lines or electrical wires.

Stay weather aware

  • Monitor the latest forecast changes to stay in-the-know. Keep up with your KSAT Weather Authority for live updates and reports on-air, online, and on the KSAT Weather Authority App.

Bexar County preparations

  • In addition to preparing your home and neighborhood, Bexar County officials are also taking the necessary precautions ahead of the heavy rain.
  • The Public Works department will have pre-positioned barriers set up near areas that are prone to flooding, and will be ready to assist in areas that require a response due to high water.
