Scattered rain showers and thunderstorms on Friday will give Utah residents a slight break from the summer heat, but heavy rainfall could potentially cause flash flooding in some parts of the state.

“A flash flood watch is in effect for portions of central Utah beginning at 2 p.m. and continuing through 10 p.m. this evening,” according to the National Weather Service. Areas where fires have scarred the landscape are the most vulnerable for flooding.

“Some of this heavy rain could strike the burn scars in the watch area," officials said. "Flash flooding along with debris flows could occur if sufficient rainfall strikes any of the burn scars.”

The flash flood watch will affect the Wasatch Mountains south of Interstate-80 in northern Utah and the Wasatch Plateau and Book Cliffs areas of central Utah.

High temperatures on Friday will be 92; Saturday will be mostly sunny, with a high near 88.
