Avalanche danger remained high along the Wasatch Front on Tuesday, the day after dozens of mountain snowslides closed down canyon roads and slowed commuters elsewhere in the wake of a major winter storm.

The Utah Avalanche Center put the mountains above Logan, Ogden, Salt Lake, Provo and Moab, as well as the Unitas under "red," or at high risk on Tuesday. The Skyline and Abajo districts were "orange," or at considerable danger for avalanches.

Slopes of 30 degrees or steeper were dangerously unstable as the heavy additional snowfall, driven by gusty winds along the crest lines, blanketed already dense layers of snow from previous storms.

More than two feet of snow fell on the northern and central mountains of Utah on Monday. Resorts topped even that in places, with 29 inches measured at Brighton's crest, while Alta had 22 at the Collins station; Park City and Solitude 18; Deer Valley and Sundance 18; Snowbird 17; Provo Canyon 14; and Powder Mountain — which was closed Monday and remained so Tuesday in the wake of an avalanche that temporarily trapped an employee in a vehicle — had 14 inches.

Powder Mountain marketing manager Jean-Pierre Goulet said Tuesday he spent about 45 minutes stranded in his truck on State Road 158 northeast of Ogden after one of a number of avalanches slid down the mountain Monday afternoon, according to the Associated Press.

Snow totals also were impressive in the region's valleys. Logan reported 13 inches; Garland 9; Wendover 7; and Salt Lake City's upper Millcreek Canyon 4 inches.

Little Cottonwood Canyon, likewise inundated Monday by snow, remained closed until 8:30 a.m. Tuesday morning, when the canyon road finally was cleared of seven snowslides. In all, about 40 small avalanches, set off by control measures, were reported in the canyon on Monday.

Big Cottonwood Canyon was open, but initially restricted to four-wheel-drive vehicles or those with tire chains. The same conditions applied along Box Elder County's Interstate 84 and U.S. 89 through in Sardine Canyon Tuesday morning.

Logan Canyon remained closed a second day due to hazardous winter driving conditions. The Utah Department of Transportation also closed down state roads 143, 14 and 158 in Iron County due to heavy snow.

The Utah County Sheriff's Office reported that due to avalanche danger the Provo River Parkway Trail was closed near Bridal Vail Falls on Tuesday.

A new storm was spreading south from Idaho on Tuesday, and by late evening Utah's northern valleys were due to measure several inches of fresh snow. Mountain totals were expected to be at half-a-foot or more.

The Salt Lake and Tooele valleys looked for 2-4 inches by nightfall with high temperatures hovering near 30 degrees on Tuesday. Wednesday's forecast called for pre-dawn lows in the upper-teens with the day's highs rising a mere 5-7 degrees beyond that. There was a 30 percent chance for additional snow through the midweek period.

Southern Utahns were to dodge precipitation in general with daytime highs in the mid-40s and overnight lows in the upper-20s through Thursday.

As long as storms continue to lash the state and stir the atmosphere, the Utah Division of Air Quality will happily continue rating conditions as "green," or healthy. That was the forecast statewide through Wednesday.
