A cold front could bring high winds as well.
A cold front pushing through Utah could bring flash floods and high winds to some parts of the state Tuesday afternoon and evening.
A flash flood warning from the National Weather Service is in effect for south-central Wayne County until 6:15 p.m., especially in Capitol Reef National Park, which is in the midst of its busiest season.
As of about 3 p.m., between a half-inch and an inch of rain had fallen at the park, the weather service said. Heavy rain and thunderstorms could cause “life-threatening” flooding in creeks and streams and on highways. Grand Wash and Capitol Gorge roads were closed Tuesday afternoon until further notice, park officials tweeted.
The weather service urged people to remain alert, even in areas that have not received rain, because distant rainfall can still cause dry washes, streams and rivers to flood in a matter of minutes.
The storm system also will likely bring high winds to certain parts of western Utah and northern Utah County. The Great Salt Lake Desert and eastern Box Elder County are under a wind advisory until 6 p.m., and wind gusts could reach 45 mph. A wind advisory is also in effect for cities in Utah County north of Provo, where winds could reach up to 45 mph and cause choppy conditions on Utah Lake.
In both regions, winds could blow around unsecured objects, reduce driving visibility and create hazardous crosswinds for high-profile vehicles.
The Wasatch Front could get some rain due to a “narrow band of showers” ranging from Salt Lake City to Nephi and extending across the state Tuesday night through Wednesday morning, the weather service advised.
As the cold front crosses the state late Tuesday, light snow is possible above 9,000 feet across the northern and central mountains, including the Uintas, into Wednesday morning.
Frost is possible in the Cache, Rush and Sanpete valleys, but only “outlying” areas of the Wasatch Front (near Utah Lake and Tremonton) will it. Hard freeze conditions are possible in Cache Valley, along the Wasatch Back, Bear River Valley, Sanpete Valley and near Panguitch.
Highs will be back in the low 70s in Salt Lake City by Friday and Saturday.
