SALT LAKE CITY — The second major snow storm of the week created hazardous road conditions across northern Utah Thursday morning.

The Utah Department of Transportation urges drivers to use "High Caution" along I-15, I-84 and other roads in northern Utah through 6 p.m. Thursday.

UDOT has issued the following Road Weather and Emergency Alerts:

Another round of valley and mountain snow will impact the northern half of Utah Wednesday evening through Thursday evening. Valley routes along the Wasatch Front will see some light road snow accumulations, with the most consistent snow is expected during the second half of the night and Thursday morning. This will allow for some light road snow accumulations during the Thursday morning commute along the Wasatch Front. The most widespread impacts are expected to be north of the Salt Lake Valley. Any road snow/slush impacts along I-15 from Provo on south to the I-70 Junctions will be brief and spotty at best. Most, if not all, valley routes are expected to trend wet after 9am or 10am Thursday.

Mountain routes, generally north of I-70, will see areas of road snow and blowing snow. The most widespread blowing snow and strongest winds are expected to be over Logan Summit (east of Logan), near Strawberry Reservoir (southeast of Heber/Park City), and over the Wasatch Plateau Summits of SR-31 and SR-264.

Our storm will continues Thursday night through Friday, but the majority of all road snow impacts should be confined the canyons/mountains as valley air temperatures warm. Check back Thursday for more specifics on this time-frame.
