Widespread heavy rainfall is expected to occur across the entirety of the forecast area through Monday as Tropical Storm Rachel transitions to an extratropical system to our southwest and interacts with a strong midlevel trough. Widespread rainfall amounts from 1-2" are expected across much of the forecast area, with localized amounts potentially reaching 3+" across locations such as higher terrain locations across southwest Utah, the Book Cliffs, and locations within and adjacent to the Bear River Range.
Periods of widespread precipitation will continue through Wednesday, and much colder air moving into the region on Monday will result in a transition from rain to snow above 9000 feet by Monday night. As such, accumulating mountain snowfall is expected through this period, impacting travel especially on high-elevation seasonal routes.
