Road Weather Highlights

Strong Wind TUE & Road Snow/Slush TUE Evening


 

Forecast Period: 12 A.M. Tuesday through 11 P.M. Tuesday

Text Updated: Tuesday 2/21/2017 at 12:00 A.M.

 

Gusty southerly winds continue across the western half of the state, with wind gusts of 45-55 mph expected through Tuesday afternoon. Localized wind gusts may approach 60 mph in wind-prone areas during the overnight hours, including portions of I-80 between Rowley Jct. (mp 77) and Lake Point Jct. (SR-201), Sardine canyon through US-89, SR-36 around Stockton Bar, and US-6 through Eureka. Strong southerly winds will continue on Tuesday ahead of an approaching cold front and will finally subside early Tuesday evening. Motorists of lightweight and high profile vehicles should travel with caution, especially on west-east oriented roadways.

The cold front will then spread heavier precipitation across Northern Utah late Tuesday afternoon and evening. Road snow levels will fall from higher mountain routes down into mountain valleys and canyons during this time. Some mountain routes may quickly transition from wet to snow-covered under heavier snowfall Tuesday evening. Far Northern Utah valleys will also see a transition from rain to snow by Tuesday evening, bringing the threat of road slush to areas north of Ogden into Cache Valley. A mix of rain and snow may develop across the Wasatch Front between Ogden and Salt Lake City later Tuesday evening, with road slush becoming possible on the eastern benches as snowfall rates increase. Lowest valley routes south of Ogden, will likely stay wet through 11 P.M. Tuesday, but brief road slush may be a concern if snowfall becomes heavy enough. Motorists are advised to use caution and TravelWise. The following major routes are expected to have weather-related travel concerns during the forecast period:

  • I-15, ID border to Black Ridge (mp 42)
  • I-80, Entire Route
  • I-84, Entire Route
  • US-89, ID border to Farmington
  • US-40, I-80 Jct. to Pinion Ridge/SR-208
  • US-6, NV border to I-15
  • US-191, between WY border & Vernal

 

See the travel weather highlights graphic below, which is valid from 12 A.M. Tuesday through 11 PM Tuesday.
