From the western desert to its Wyoming and Colorado borders, central Utah received fresh snow early Tuesday, ranging from an inch or two in the valleys to 4-5 inches in the mountains.
The southern Wasatch Range especially was affected and remained under a Winter Weather Advisory into Tuesday evening.
That fresh snow fell on already ice-packed road surfaces, making for more than a few commuter headaches. The Utah Highway Patrol and local law enforcement agencies reported dozens of minor crashes and slideoffs.
Eastbound semi-trailer rigs were being required to don tire chains to traverse Parleys Canyon, while both Big and Little Cottonwood canyons were restricted to four-wheel drive and chained vehicles.
