ST. GEORGE — The National Weather Service in Salt Lake City has issued a flash flood watch for Southern Utah and surrounding areas including Washington, Iron and Kane counties; Glen Canyon and Lake Powell; south-central Utah and the southern mountains.
Rainfall is expected to increase throughout the area, becoming widespread and locally heavy through late Thursday night. Thunderstorms will enhance the heavy rainfall potential during the day Thursday.
The potential for flash flooding in these areas continues through Thursday night.
Areas with a higher risk of flash floods include slot canyons, normally dry washes and small streams. The National Weather Service warns that these areas should be avoided. Flooding of urban areas with poor drainage and basements is also possible.
Instructions
A flash flood watch means that conditions may develop that lead to flash flooding, a very dangerous situation. Monitor local broadcasts if possible and be prepared to take swift action should a flash flood warning be issued.
Precautionary/preparedness actions
Should the flash flood watch change to a warning, that means flooding is imminent and it is important to know where you are in relation to streams, rivers or creeks which can become killers in heavy rains. Campers and hikers should avoid these areas until the storm passes.
Move to higher ground now. Act quickly to protect your life.
Turn around. Don’t drown.
If you are traveling in these areas, be aware of flash flooding and avoid any washes and dry slot canyons. Remain alert for flooding even in locations not receiving rain. Dry washes, streams and rivers can become raging killer currents in a matter of minutes, even from distant rainfall.
Do not drive your vehicle into areas where the water covers the roadway. The water depth may be too great to allow your car to cross safely.
