SOUTHERN UTAH – A flash flood warning has been issued by the National Weather Service southeast Washington County and northeastern Mohave County, Ariz. until around 6:15 p.m. Wednesday.
At 1:56 p.m. the NWS Doppler radar indicated very heavy rain from a thunderstorm near Colorado City. The storm producing very heavy rain was nearly stationary.
Colorado City, Ariz., and state Route 389 near the Utah/Arizona border.
Rains from thunderstorms in the area may also affect Hurricane, LaVerkin, Leeds and Washington.
Flash flooding is expected on area roadways around underpasses and in normally dry washes and low lying areas. Flash flooding is nature’s number one killer. Never try to cross a flooded roadway or walk through floodwaters.
The National Oceanic and Atmospheric Association and the National Weather Service offer safety rules for flash flooding:
Conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.
- Flash flood waves, moving at incredible speeds, can roll boulders, tear out trees, destroy buildings and bridges, and scour out new channels. Killing walls of water can reach heights of 10 to 20 feet. You will not always have warning that these deadly, sudden floods are coming. When a flash flood warning is issued for your area or the moment you first realize that a flash flood is imminent, act quickly to save yourself. You may have only seconds.
- Most flood deaths occur in automobiles. Do not drive your vehicle into areas where the water covers the roadway. Flood waters are usually deeper than they appear. The road bed may not be intact under the water. Just one foot of flowing water is powerful enough to sweep vehicles off the road. If the vehicle stalls, abandon it immediately and seek higher ground. Rapidly rising water may engulf the vehicle and its occupants and sweep them away. Case in point: In July 2013 a tour bus in Arizona tipped over and got swept nearly one-half mile down an otherwise dry wash.
- Do not hike rivers and especially slot canyons while flash flood warnings are in place.
- Do not hike alone and always tell someone where you and your buddy and others are going.
- Get out of areas subject to flooding. This includes dips, low spots, canyons, washes, et cetera.
- Avoid already flooded and high velocity flow areas. Do not try to cross a flowing stream on foot where water is above your knees.
- Be especially cautious at night when it is harder to recognize flood dangers.
- Do not camp or park your vehicle along streams and washes, particularly during threatening conditions.
- During any flood emergency, stay tuned to your NOAA weather radio, commercial radio, or television, follow St. George News at STGnews.com and St. George News Facebook for weather alerts and updates relevant to Southern Utah. Information from the national weather service and disaster and emergency services may save your life.
Turn around, don’t drown.
