Flash Floods: The Nation’s Top Storm-Related Killer
The monstrous, swift-moving flood that swept through the Hill Country of Texas on Friday, killing at least 59 people and leaving more people missing, was a flash flood, the nation’s top storm-related killer. Among those missing are 11 girls and a counselor attending a summer camp.
What are Flash Floods?
According to the National Weather Service, a flash flood is flooding that begins within six hours, and often in as little as three hours, of heavy rainfall. This type of flooding is extremely dangerous and can catch people off guard, resulting in devastating consequences.
Waters rise so quickly that people are caught off guard, according to the weather service. Many people run into trouble while traveling. If at home or work, the water can rise so quickly people are trapped before they have time to think about escape.
The Guadalupe River Flood Disaster
That is just what happened to residents along the Guadalupe River in Kerr County and the surrounding area after at least 10 inches poured from the sky early Friday morning. Fast-moving waters along the river rose 26 feet in just 45 minutes before dawn Friday, washing away homes and vehicles.
The danger was not over as more heavy rains were expected Saturday and flash flood warnings and flood watches remained in effect for parts of central Texas. The situation was dire, and the community was left to pick up the pieces and wonder how such a disaster could have occurred.
Advance Notice and Warnings
On Thursday afternoon, the National Weather Service issued a flood watch, estimating rising water of up to 7 inches in spots. A “watch” means conditions are favorable for a flood and people should be prepared, but hazardous conditions might not develop.
The watch was upgraded to a flood warning overnight, a notice that impacted 30,000 people. A warning is issued when flooding is imminent or occurring, the weather service says.
Lt. Gov. Dan Patrick said the potential for heavy rain and flooding covered a large area and “everything was done to give them a heads-up that you could have heavy rain.” However, when asked about how people were notified in Kerr County so that they could get to safety, Judge Rob Kelly, the county’s chief elected official, said: “We do not have a warning system.”
Lack of Preparation and Warning Systems
When reporters pushed on why more precautions weren’t taken, Kelly responded: “Rest assured, no one knew this kind of flood was coming.” This lack of preparation and warning systems has raised questions about the effectiveness of the emergency response and the measures in place to protect the community.
The Dangers of Flash Floods
Last year, 145 people died in flash floods, according to the weather service. On average over the past 30 years, floods have claimed 127 lives annually. Flash floods are a serious threat to public safety, and it is essential to understand the risks and take necessary precautions.
Floods and Vehicles
Nearly half of all flood-related fatalities involve vehicles. Flood deaths affect all age groups. Many people don’t realize that a car becomes difficult to control in just 6 inches of water and can be swept away in as little as 18 inches.
So instead of finding a detour, too often people try to drive through water at underpasses or other low-lying areas. This can be a fatal mistake, and it is crucial to exercise caution and avoid driving through flooded areas.
Flash Floods Can Happen Anywhere
It can happen anywhere, according to the weather service, which says “the normally tranquil streams and creeks in your neighborhood can become raging torrents if heavy rain falls overhead.” An area can be flooded even without rain — if it’s downstream of a torrential rainstorm and a swollen stream heads its way.
Hurricanes, tropical storms, non-cyclonic weather systems carrying heavy rain and dam failures are some weather events that can cause flash flooding. They can happen in rural areas or in large cities, and it is essential to be prepared and aware of the risks.
Conclusion
Flash floods are a serious threat to public safety, and it is crucial to understand the risks and take necessary precautions. By being aware of the dangers and taking steps to prepare, we can reduce the risk of injury or death from flash floods. It is also essential to have effective warning systems and emergency response plans in place to protect communities from these devastating events.
