SALT LAKE CITY — A predicted post-Super Bowl storm began dumping snow across the Wasatch Front overnight, turning the Monday morning commute into a challenging mess.

A winter storm advisory is in effect until 10 p.m. Monday.

Traffic

Several spinouts and crashes were reported from Willard to Spanish Fork, according to the KSL Traffic Center. The traffic areas hit the hardest in the 5 a.m. hour appeared to be on I-15 between Midvale and Murray, and the I-215 belt routes on the east and west sides of the Salt Lake Valley.

As of 7:45 p.m., Utah Highway Patrol troopers had investigated 313 crashes statewide since midnight. Most of these were in Salt Lake County. Motorists should expect to double their typical driving time, the traffic center said.

A car crash caused a power outage that impacted 2,656 customers in the South Salt Lake and Sugar House area about 3:20 p.m., according to Rocky Mountain Power. Power had been restored by 4 p.m.

About 1:40 p.m., a southbound car slid off I-15 into a pond at 1000 North, according to Salt Lake City Fire Department officials.

One individual was released on scene and the other was transported to a hospital as a precaution, officials said.

During an early February snow storm last year, which started Feb. 5, 2019 and continued through Feb. 6, 2019, troopers responded to 410 crashes across the state.

#RoadUpdate: Road conditions in #BCCroad#SR190 remain snowy with low vis. Be very cautious, esp in the lower half of the canyon. While ❄️ is forecasted to let up late this evening, low temps will build ice. Blowing snow is also a concern. @UDOTTRAFFIC@CanyonAlerts#utwxpic.twitter.com/SK3MtntKCx — UDOT Cottonwood Canyons (@UDOTcottonwoods) February 3, 2020

Officials urged Utahns not to drive on Monday.

"We're recommending that if people have flexibility with their travel (Monday), that they stay off the roads as much as possible," said Utah Department of Transportation spokesman John Gleason. "Our primary focus is keeping everyone safe, and just having fewer people out on the roads (Monday) during this major snowstorm, that's going to allow us to accomplish that goal."

Chains or four-wheel drive are required in Big and Little Cottonwood canyons. Little Cottonwood Canyon and state Route 210 was scheduled to close at 1:30 p.m. for avalanche mitigation. Chains are required for semitrucks in Parleys Canyon.

Up north, I-84 is closed from the Utah state line to the I-86 junction in Idaho, just east of Burley, due to drifting snow and gusty winds.

As latest storm provides Utah with lots of snow, how to track which roads have been plowed A storm dropped several inches of snow across the Wasatch Front and northern Utah Monday. Here's how much has fallen and how to find streets that have been plowed.

Weather

KSL meteorologist Dan Guthrie anticipated Utah would see half its snowfall total overnight and half throughout the day on Monday. Though the storm will abate by Tuesday, he said, another storm system could blow through the state on Wednesday.

During the Monday storm, expect about 4-8 inches of snow in the valleys throughout northern and central Utah, Guthrie said. Some cities will see higher totals — forecasts anticipate about 10 inches for Salt Lake City and 12 inches for Tooele. The mountains should pick up about 1-2 feet of snowfall from the storm.

Warning: A special avalanche advisory for those unaccustomed to avalanche danger was issued in the valleys and the benches, according to the Utah Avalanche Center. Avoid steep terrain. The avalanche danger is considerable for the Salt Lake, Logan, Ogden, Uintas and Provo area mountains.

There was a steep dropoff in high temperatures between Sunday and Monday. While Salt Lake City topped out around 56 degrees on Sunday, high temperatures over the next three days will plummet to 26, 25 and 27 degrees.
