The storm is expected to lay down 8 to 18 inches of snow in parts of the Wasatch Back.
The National Weather Service says the storm will impact roads and travel during the Friday morning commute.
The Utah Department of Transportation may activate traction laws requiring drivers to use chains, four-wheel drive or snow tires in canyons and similar areas.
“[Friday] is likely where we're going to see the bulk of our accumulations over the next few days,” Meteorologist Thomas Geboy said. “For Deer Valley and Park City Mountain Resort, based on the way things are looking right now, we could see over half a foot, maybe 8 inches plus.”
Snow will pause Sunday, and then the NWS says a weaker storm will drop a few flurries Monday.
Thaynes Canyon reported a foot of snow after last weekend’s storm which put Utah’s statewide snowpack above the historic median too.
The Utah Avalanche Center says danger remains considerable Dec. 6 at mid- and upper elevations where there’s a persistent weak layer.
The UAC says the north-facing slopes are especially dangerous because they’re tending to have older and weaker snow. It recommends avoiding anything 30 degrees or steeper.
