Salt Lake City, Utah – Mountain travel across much of Utah could deteriorate rapidly late tonight as accumulating snow moves into multiple high-elevation corridors, creating hazardous driving conditions through Wednesday and into early Thursday.
According to the National Weather Service in Salt Lake City, Winter Weather Advisories go into effect at 11 p.m. tonight for the Southern Mountains, Wasatch Plateau, Book Cliffs, Wasatch Mountains, and Western Uinta Mountains. Snowfall totals of 6 to 12 inches are expected in the Wasatch Mountains and Southern Mountains near Brian Head and the Tushar Range, with locally up to 15 inches possible in the upper Cottonwoods. Areas above 7,500 feet on the Wasatch Plateau and Book Cliffs could see 5 to 10 inches.
The most intense snowfall is expected between 3 a.m. and late Wednesday afternoon, especially along the I-80 corridor through the Wasatch, including Brighton, Alta, Logan Summit, and the Mirror Lake Highway. Snow-covered roads and reduced visibility could slow traffic on mountain passes and recreation routes, while intermittent heavy bursts increase the risk of slide-offs.
Southern Utah mountain communities near Brian Head and Alton may see prolonged winter driving conditions through early Thursday morning, with snow continuing until around 5 a.m. Thursday. Advisories for northern mountain zones remain in effect until 11 a.m. Thursday.
UDOT urges drivers to slow down, allow extra braking distance, and avoid unnecessary mountain travel during peak snowfall. Road conditions can be checked at udottraffic.utah.gov. Additional advisories remain possible if snowfall rates increase or linger longer than expected.
