SALT LAKE CITY – The National Weather Service issued some winter weather advisories ahead of another storm that could provide more than a foot of snow in the Wasatch Mountains and across northern Utah from Friday night through Saturday.

State Route 210 in Big Cottonwood Canyon will close for uphill traffic at 12:30 a.m. Saturday and will close for downhill traffic at 1 a.m. for UDOT avalanche and safety check. Roads will reopen at 8am on Saturday.

Traction laws

Traction laws are in effect at Big Cottonwood and Little Cottonwood Canyons in Salt Lake County as of 7 p.m. Friday. Traction devices such as snow tires or chains are required on all vehicles in both directions for State Routes 210 and 190, according to UDOT.

All vehicles traveling on I-80 through Parley’s Canyon are required to have traction devices. Eastbound drivers can stop and chain the right side of the road at the 129 mile post and westbound drivers can chain the 146 mile post on the right side, UDOT said on Twitter.

Traction laws are also in force in Sardine canyon in Cache County on US 91 in both directions, between the milepost post 2 and the milepost at mile 17. Meteorologists with the National Weather Service said Friday the storm would cause “dangerous travel” through passes tallest mountain like Logan Canyon.


Northern Utah and Wasatch Front

Heavy snow showers move through central and northern Wasatch Front until 10 p.m. Friday, the National Weather Service said on Twitter. The cold front of the storm has lowered the temperature to 20 degrees and, although the roads have remained wet, they could freeze quickly and drivers are urged to be careful, especially as “flyovers could freeze quickly,” said the NWS .

The latest storm is part of a system moving from the Pacific Northwest, according to KSL meteorologist Grant Weyman. The snow flurries reached northern Utah and around the Wasatch Front Friday morning in a smaller storm than the one that followed.

The strongest things are expected from Friday night through Saturday. The weather service’s winter weather advisories, which were first issued Thursday and updated on Friday, will go into effect Friday afternoon through Saturday night. An advisory indicates that snow accumulations are expected to reach 10 to 20 inches in the Wasatch Mountains north and south of I-80 and in the western Uinta Mountains, with some “locally higher amounts” possible in some areas. .

“Winter driving conditions can be expected on all higher elevation routes, especially the upper Cottonwood Canyons, I-80 near Parley’s Summit and Logan Pass from Friday night to Saturday,” the alert stated. .

Possible gusts of wind could be associated with the storm, but the weather service removed a warning about negative 25-degree cold winds in an update to its winter weather advisory on Friday.

Valleys of the Wasatch Mountains

A second winter weather advisory was issued for the Wasatch Mountain valleys, Heber City, Huntsville and Park City areas, which also went into effect from Friday afternoon through Saturday night. The weather service stated that travel may be impacted along the Wasatch Front on Saturday morning.

The agency predicted 3-6 inches of snow will fall in those areas, with “locally higher” amounts possible in the Ogden Valley. The alert added that mountain valleys south of I-80 could receive 3 to 6 inches of snow; some parts of the Ogden Valley could receive more than 6 to 8 inches of snow from the storm.

the The National Weather Service published an image showing the expected snow totals from the storm for Sunday morning, which is approximately the time the storm will have passed. In addition to the areas listed in the advisory, cities such as Brigham City, Logan, Nephi, Ogden, Provo, Salt Lake City and Tooele are forecast to receive between 1 and 3 inches of snow.

Central Utah

A third advisory was issued Friday morning for higher elevation areas of central Utah, including places like Cove Fort, Fish Lake, Koosharem, and Scofield, which went into effect at 8 p.m. Friday and runs through most of of Saturday. He advises that some areas can receive 4 to 10 inches of snow.

“Occasional winter driving conditions can be expected, particularly along US 6 from Spanish Fork Canyon to north of Price and the higher peaks of I-70,” he said.

All three notices encourage motorists to “slow down and be careful when traveling.”

The storm is not expected to bring the amount of snow accumulation in the state back to average, but it is expected to at least help the figure continue to advance. Utah’s snow cover was 77% of normal for this point in the year as of Friday morning, according to SNOTEL data.

The additional snow could also pose avalanche problems after the threat turned less severe than last week. As of 8 am Friday, most of Utah’s mountains had “moderate” or “considerable” avalanche risk, according to the Utah Avalanche Center. The avalanche hazard moved “high” to the mountains near Logan.

Meanwhile, the forecast calls for better weather heading into March. Temperatures along the Wasatch front are expected to return to 40 degrees and even below 50 degrees by the middle of next week, according to Weyman.
