The flash flood watch has been issued for much of the area east of Interstate 15 and south of state Route 40. This includes Zion National Park, Capitol Reef National Park, Bryce Canyon National Park, the area around Lake Powell and Dixie National Forest. Other cities that could be affected by the flash flood watch include Kanab, Panguitch, Hanksville, Escalante and Bryce Canyon City.

Numerous thunderstorms are expected to fall along the tops of mountains Wednesday, which has potential to cause flash flooding across Southern Utah, according to the weather service. The flash flood watch will be in affect through Wednesday evening.

Flash flooding can cause concern near burn scars, slick rock, slot canyons and normally dry washes. In case of a flash flood, immediately seek higher ground and stay out of rivers, washes and slot canyons.

Most flood deaths occur in vehicles, according to the weather service. When encountering flooded roads, the weather service encourages drivers to turn around and avoid driving through flood waters.

    A paved road leading to an unbuilt development off the Airport beltway washed out, “Desert Canyons Parkway”, completely gone… and possibly another road or two near the Motocross proving grounds.
