Hurricanes, tropical storms, severe winter storms, and severe thunderstorms can all produce straight-line winds and high wind dangers. Straight-line winds are often responsible for most of the wind damage associated with thunderstorms. Despite similar damage types and wind speeds, straight-line winds should not be confused with the rotational winds of tornadoes.
It is common for thunderstorms in this Texas region to produce hazardous straight-line winds that measure up to and greater than 75 mph. It is also possible for straight-line winds to exceed 100 mph. These high winds can prove hazardous to life and property. High winds can overturn mobile homes, push moving vehicles off the road, cause roof damage to homes, push trees over on homes, vehicles, and power lines, and create flying debris.
If you are under a severe thunderstorm warning where powerful straight-line winds are possible, take shelter immediately and tune in to local media for more information.
Before the Storm
- Purchase an indoor personal notification system. These systems will alert you to any hazardous conditions that may exist.
- Walkthrough your yard and pick up any toys, lawn equipment, branches, etc., that may become flying debris should high winds form. Secure any patio furniture.
- Cut down any dead branches or trees that may hang over your house. High winds can easily break or topple dead trees.
- Make sure the roof of your house is strengthened, and secure with the appropriate hardware.
All of these actions should be taken well advanced of a high wind event. Once a severe thunderstorm warning has been issued, it will be too late to exercise these precautions.
