SALT LAKE CITY — Valley rain and mountain snow is expected throughout Utah on Thursday as another three-day storm moves through the state.
As of 12:30 p.m., traction laws were put in effect for Little Cottonwood and Big Cottonwood canyons in Salt Lake County, according to the Utah Department or Transportation: Tire chains or four-wheel drive are required for all vehicles heading up state Route 190 in Big Cottonwood Canyon and state Route 210 in Little Cottonwood Canyon.
Snow started falling on I-80 in Parleys Canyon about 5 a.m. Thursday, according to KSL Weather Meteorologist Grant Weyman. Valleys in northern Utah will see mostly rain Thursday, but snow is possible in the valleys Friday and Saturday, Weyman said.
Road snow was expected to affect mountain routes from I-80 north throughout Thursday morning, according to the Utah Department of Transportation. The snow will be moving south through Utah Thursday and will eventually affect the Wasatch Plateau in central Utah, as well as the Soldier Summit area on U.S. Highway 6 between Spanish Fork and Price, UDOT said.
Valleys north of Ogden, including Cache Valley, could see snow accumulation on the roads on Thursday morning through Friday morning, according to UDOT.
Another THREE DAY storm is on the way! It means rain at first for most of us... but snow will follow... be ready for it Friday morning, and again on Saturday. pic.twitter.com/A7Kjo9vl99— Grant Weyman (@KSLweyman) December 11, 2019
Valleys in other areas throughout the Wasatch Front will see mostly wet road conditions through Friday, but little road snow, UDOT said. Benches from the Salt Lake area north to Ogden could see slushy roads.
Some mountain areas could see one to two feet of snow by Saturday, Weyman said.
On Friday, temperatures are expected to drop, which will make snow possible in the valleys across northern Utah, Weyman added. Snow accumulation is likely in the bench areas on Friday.
Drivers heading up mountain or canyon routes should be prepared for driving restrictions at any time when adverse weather is possible, UDOT said.
