SOUTHERN UTAH – The National Weather Service has issued a “flash flood warning” for Washington County and a “flash flood watch” for portions of Washington, Kane and Garfield counties.
Flash flood warning
At 1:32 p.m., Doppler Radar indicated a thunderstorm producing heavy rain over LaVerkin Creek, just north of the Toquerville and west of Zion National Park. Radar rainfall estimates that more than an inch has fallen in a short period of time in this area. The warning for this area remains in effect until 4:30 p.m. Tuesday.
Anyone traveling near this area is admonished to use caution to ensure their safety.
Flash flood watch
The National Weather Service has also issued a “flash flood watch” for south central and southeast Utah until 11 p.m. Tuesday. A flash flood watch means conditions may develop that lead to flash flooding, which is a very dangerous situation.
A moist air mass ahead of an upper low in Nevada will move north into Southern Utah. This watch affects San Rafael Swell in south central Utah and Glen Canyon Recreation Area/Lake Powell, including the cities of Green River, Hanksville, Kanab, Escalante and Bullfrog.
Slot canyons and normally dry washes may fill with water due to heavy rain. The heavy rain may occur at some distance away and travel downstream into slot canyons or normally dry washes.
Anyone near these areas is advised to monitor later forecasts and be prepared to take action should flash flood warnings be issued.
