When is tornado season in Texas?

Tornado season in Texas runs April through June each year — these months see cold winter air give way to summer heat, forming a collision of warm and cool air masses that turn into twisters. While Texans can see tornadoes 12 months of the year, they should be especially prepared toward the end of spring and beginning of summer.

When adjusted for area, Galveston County in East Texas along the Gulf of Mexico sees the most tornadoes of any other area in the Lone Star State. It saw around 33 tornadoes per 100 square miles between 1950 and 2021. [5]

This is followed by Johnson County (located just south of Fort Worth, Texas) and Harris County (home to Houston, Texas), which both saw an average of 14 tornadoes per 100 square miles between 1950 and 2021.

Where in Texas is Tornado Alley?

Tornado Alley typically refers to the region in the United States where tornadoes occur most frequently, which includes West and North Texas, Oklahoma, Kansas, Nebraska, South Dakota, and parts of Colorado and New Mexico.

Does home insurance in Texas cover tornado damage?

Homeowners insurance in Texas covers damage caused by tornadoes, including the wind, hail, and rain that accompany them. However, water damage from flooding that occurs during a tornado would not be covered under your standard home insurance policy — you’ll need separate flood insurance for that.

The one exception is if you live in an area at high risk for wind damage — your home insurance policy might exclude damage from wind and hail. In this case, you’ll need to purchase a separate wind-only insurance policy to fill that coverage gap. Texas windstorm policies are available to homeowners through private insurers or the Texas Windstorm Insurance Association (TWIA).

Texas has a separate windstorm deductible for tornado damage

If your home is damaged in a tornado in Texas, your windstorm deductible will be triggered. This is separate from your standard homeowners insurance deductible and applies to wind and hail damage from any type of windstorm — it doesn’t have to be a named storm or hurricane in Texas.

Windstorm deductibles in Texas are either a flat dollar amount, like $2,500, or a percentage of your policy’s dwelling coverage limit — usually between 1% and 5%. You can choose your deductible when you purchase your home insurance or windstorm insurance policy. A higher deductible leads to lower insurance rates, and vice versa.

How to prepare for tornado season in Texas

From installing storm-proof shutters on your windows to knowing where to take shelter should a disaster strike, here are a few ways to prepare for tornado season in Texas.

1. Get your home ready for severe weather

This includes trimming tree limbs that hang close to your roof, removing dead trees from your yard, cleaning up any heavy debris (i.e. branches, bricks, firewood) on your property, and moving lawn furniture inside when a twister nears. If you live in an area especially prone to tornadoes, consider installing storm-proof shutters on your windows and garage door or upgrading to a Class 4 impact-resistant roof — both of which can earn you serious discounts on your home insurance rate.

2. Make an emergency kit

FEMA recommends packing a few bags with essentials you can easily grab as you take shelter when a tornado nears. [8] Some items to include in your emergency kit include: water, non-perishable foods and baby formula, a can opener, moist towelettes and trash bags, batteries, flashlights, a first aid kit, portable cell phone chargers, a battery-powered radio, and a whistle to signal for help.

3. Find a place to take shelter

While no place will keep you completely safe during a tornado, hunkering down in a basem*nt or inside a windowless room on the lowest floor of your home is your safest bet. For even more protection, take shelter under something sturdy like a heavy table or workbench, cover yourself with a blanket or mattress, and protect your head from flying debris.

4. Know the signs of a tornado

If you live in an area of Texas at high risk for tornadoes, knowing what to look for during a severe weather system can help you stay prepared. Be on the lookout for rotating, funnel-shaped clouds, low-lying clouds of debris, large hail, a dark or green-colored sky, and a loud roar that sounds like a freight train — all of these could forewarn a tornado is near.

5. Sign up for your community’s warning system

Anyone can sign up for severe weather alerts from the National Weather Service via text, email, or phone. In addition, your specific community likely has their own emergency alert system you can sign up for to receive weather alerts (here’s where to sign up if you live in or around Austin, Fort Worth, or Houston). A quick google search “CITY + emergency notification alerts” can help you sign up for notifications in your area.

Many cities throughout Texas also have outdoor warning siren systems to warn residents to take shelter indoors during extreme weather conditions, including tornadoes. These outdoor sirens are most prevalent in North Texas where tornadoes are the most prevalent.

6. Stay up to date on changing weather conditions

On top of signing up for your community’s weather alerts and keeping your ears to the ground for any outdoor warning sirens, staying up to date on changing weather conditions via your local news and radio stations or even through social media can help you know when a tornado is near.
