SALT LAKE CITY — Large portions of central and southern Utah will be under a flash flood watch Tuesday while the northern half of the state will also see critical fire weather as severe weather moves into the Beehive State.

The southern Wasatch Front and northeastern Utah could see over 1″ of rain by the end of the week, according to KSL meteorologist Grany Weyman.

Cooler temperatures will follow the storms, which will also help clear wildfire smoke that has lingered over the state.

The main threats with Tuesday’s storms are heavy rain, strong winds and possible hail.

Flash Flood Watch

The National Weather Service said a flash flood watch will go into effect at noon Tuesday, with meteorologists keeping an eye on slot canyons, normally dry washes and burn scars.

The watch was extended Tuesday morning to include Zion National Park and Washington County, along with Summit and Duchesne counties.

Burn scars will be the primary concern for northern Utah as slow-moving storms hit the area.

This flash flood watch lasts through Wednesday night.

Red Flag Warning

Before the rain arrives, a red flag warning will be in effect from the Utah-Nevada state line to the Wasatch Front, extending south toward Interstate 70.

Forecasted gusty winds, thunderstorms and large hail could lead to rapid fire growth or extreme fire behavior. These conditions could lead to new lightning-caused fires and potential fire growth — a concern the Park City Fire District expressed as crews continue to battle the Parleys Canyon Fire.

State fire officials said the blaze had burned 541 acres and was 21% contained as of Tuesday morning. Residents of Summit Park, upper Pinebrook and Lambs Canyon are all under mandatory evacuation orders, which may last through Thursday.

Water runoff is a possibility along burn scars if significant rain occurs.
