Mudslides Shut Down Diamond Fork Road as Heavy Rain Sparks Flooding Across Utah

A popular recreation corridor, Diamond Fork Road, was shut down at Monk’s Hollow in Diamond Fork Canyon after mudslides buried the pavement, according to the Utah County Sheriff’s Office. County road crews are attempting to reopen the road, but officials warned that the volume of debris could keep it closed for much of the weekend. The mudslides coincided with a broader storm system that dropped over an inch of rain at several mountain sites, triggering flash-flood warnings across southwest Utah, including at Zion National Park, Hildale and Hurricane.

In the Wasatch Front, Salt Lake City logged 0.49 inches of rain, while the Upper Avenues and South Salt Lake neighborhoods each recorded more than 1.5 inches, causing street flooding. A brief tornado warning— the first in fifteen years—was issued for a storm in Tooele County before it dissipated. Additional scattered storms are expected Friday evening, with a high-pressure ridge moving out on Saturday, reducing precipitation to higher elevations.
