SALT LAKE CITY — A major winter storm prompted several school districts in Utah to cancel classes and turned the morning commute into a mess along the Wasatch Front Wednesday.

Utah Highway Patrol troopers have responded to 410 crashes across the state since snow began falling Tuesday, officials said. Of those crashes, 211 were reported between midnight Wednesday to early Wednesday afternoon, Utah Highway Patrol said on Twitter.

Many places across the state have received more than 1 foot of snow since Tuesday, the National Weather Service reported. For example, Millcreek and Tooele had received 15 1/2 inches of snow as of noon Wednesday.

In southern Utah, Cedar City reported 12.2 inches as of 5 a.m. Wednesday.

Utah's mountains also received several feet of snow. Brighton Crest in the Wasatch Mountains led the reports with 63 inches of new snow as of 5 a.m. Wednesday, according to the National Weather Service.

National Weather Service meteorologists forecasted more snow for Salt Lake County Wednesday afternoon. Officials said a lake effect snow band across Salt Lake County was expected to bring rates of 1 to 2 inches of snow per hour.

The agency tweeted that more snow was also expected in Salt Lake and Davis counties Wednesday night into Thursday morning.

"Generally, (1 to 4 inches), with locally higher amounts possible in lake effect, but some uncertainty exists regarding lake effect strength and location," the agency tweeted.

"If you have any flexibility with your schedule or if you can work from home, today is the day," Utah Department of Transportation spokesman John Gleason said in a tweet. "Please avoid driving this morning if possible. UDOT snow plows are out in force, but driving conditions remain difficult this morning. Please stay safe!"

The worst reported crash was an 11-vehicle pileup that closed southbound I-15 near 2300 North in Salt Lake City for almost two hours. Details about the crash, including the severity of injuries, weren't immediately released, but the freeway wasn't cleared and reopened until 12:30 p.m.
