How to Prep for a Flood Threat in Texas

Texas has experienced more catastrophic flooding events in 2026 than almost any other year on record — and preparation before floodwaters rise is the single most effective tool available to every Texas family. Here is exactly what to do.

Know Your Flood Risk Before Any Storm Arrives

Flood risk is widespread and fast-moving — just 6 inches of water can knock you down, while 12 inches can move a car — and risk is not limited to coastal areas. Start by checking the FEMA flood map portal by entering your address to determine your flood zone designation. However, remember that over 25% of all flood claims occur outside designated high-risk zones — meaning no Texas home is truly immune. Visit texasflood.org for Texas-specific flood resources and TexasReady.gov for all-hazards preparedness information.

Build Your Emergency Kit Now — Not When It's Raining

Build an emergency kit with essentials such as non-perishable food, water, a flashlight, first-aid supplies, and any necessary medications — and don't forget to include supplies for pets. Stock at least 72 hours of water at one gallon per person per day. Collect and safeguard critical financial, medical, educational, and legal documents and records, and back up all documents in a waterproof bag with electronic copies stored securely.

Protect Your Property Before the Storm Hits

To stop appliances from shorting out and remove the risk of electrocution, turn off the main circuit breaker. Install check valves in sewage lines to stop floodwater from backing up into your drains, install a water alarm and sump pumps with battery backup, keep gutters and drains clear of debris, and raise the electric panel, water heater, and heating system if they are vulnerable to flooding. Before a storm arrives, move important objects and valuables to higher floors of your house.

Make a Family Communication Plan

Experts recommend Texans prepare before storms arrive by creating an emergency plan, identifying evacuation routes, designating a meeting place, and discussing how family members will communicate if separated. Know your neighbors and build a strong community network to increase your area's readiness level in an emergency — and sign up for your county's emergency alert system before a threat develops.

Never Drive Through Floodwaters

One of the biggest mistakes drivers make is underestimating the depth and force of floodwaters — the safest choice is always to turn around; don't drown. A car will float in only a few inches of swiftly moving water — moving floodwaters can sweep away your car in a matter of seconds.
