Texas Driving and Severe Weather Severe weather is a frequent threat in Texas in the spring months. Severe thunderstorms, carrying with them the potential for heavy rainfall, large hail, damaging winds and even tornadoes, pose a threat to travel anywhere in the state. Heavy rain makes roads and streets slick and dangerous. Hail can break windshields, while thunderstorm winds stir up dust and dirt, and when mixed with rain or hail, again can drop visibility to near zero with little warning. Flash Flooding, the rapid rise in water along a stream or dry creek bed due to heavy rains or releases of water upstream, is the number one cause of weather-related deaths in Texas.
Most deaths occur when motorists try to drive through flooded low water crossing.
There is really only one safety rule - stay out of deep water. If your vehicle stalls in deep water, you should leave it and move to higher ground if you can do so safely. Lightning is the second greatest weather-related treat to life in Texas . You are generally safe from lightning inside your vehicle, as long as you are not touching metal. You are safer because the vehicle spreads the lightning charge around its outer shell, diluting the charge before it leaks into the ground through the tires.
