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.
Strong winds will continue over west central and southwest Utah on Sunday, with wind gusts to 80 mph for the mountains and 60 mph in the valleys. Use caution when traveling through this area! #utwx
Winds will increase across northern Utah from 2 PM through 9 PM as the remnant circulation of Rachel moves through. Widespread wind gusts of 45 to 55 mph are expected, with isolated higher gusts in terrain favored locations possible.
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.
A much colder airmass moving in Monday night will result in increasing chances for freeze conditions Tuesday through late week for high elevation valleys. Those in impacted areas should take action to protect sensitive crops and vegetation.
