Since flash flood watches and warnings are often far more numerous during Texas summers than tornado alerts, individuals who never experience flooding firsthand may grow complacent and think “that’s not near me,” or “that won’t really happen here.” But when it does happen “here,” or when traveling across the state, the surprising power of a low level of rushing water can catch people off guard and is a big reason why flooding is the leading weather-related cause of death in Texas. Other misconceptions are that flooding stops when rain stops (floodwaters are often picking up force in the aftermath) and that only low-lying areas are at flood risk–flooding can happen anywhere, even in urban areas at high elevation, as impermeable surfaces like concrete and asphalt prevent water absorption, causing rapid runoff.
Here is some helpful advice regarding flash flooding from the Texas Department of Transportation:
- “Turn Around, Don’t Drown” — Never walk, swim or drive through still or moving flood waters. The water may be hiding dangers such as debris, tree branches, power lines or damage to the road. Just 6 inches of fast-moving water can knock down an adult and cause motorists to lose control of their vehicle, even a pickup truck or SUV.
- Stay informed about weather conditions when you are driving (many free weather alert apps can tailor weather news and alerts for your exact location; click here to learn about Richardson’s public warning systems and how to sign up).
- Be especially careful driving at night when it can be harder to see flood dangers.
- If your vehicle stalls in water, leave it and move to higher ground if you can do so safely.
