Avalanche Advisory
Advisory: Skyline Area Mountains Issued by Craig Gordon for Saturday - January 11, 2014 - 6:39am
bottom line

A HIGH avalanche danger exists on steep, upper elevation, wind drifted slopes, especially those facing the north half of the compass. Both human triggered and natural avalanches are very likely. Slopes with an easterly component to their aspect are most dangerous.

A CONSIDERABLE avalanche danger is found at mid elevations where human triggered avalanches are likely on steep, wind drifted slopes.

Wind sheltered terrain offers LOW avalanche danger




avalanche warning

THIS AVALANCHE WARNING IS FOR THE MOUNTAINS OF NORTHERN AND CENTRAL UTAH, TO INCLUDE THE WESTERN UINTA MOUNTAINS AND THE MANTI-SKYLINE. VERY DANGEROUS AVALANCHE CONDITIONS EXIST THROUGH THE WEEKEND...AVOID BEING ON OR BENEATH STEEP MOUNTAIN SLOPES...AS AVALANCHES MAY BE TRIGGERED LOW ON THE SLOPE AS WELL.

special announcement

A huge shout out and many thanks to Jared and the team from Big Pine Sports in partnership with Arctic Cat for suppling the Utah Avalanche Center with this bitchin' new loaner sled for the 2013-14 season.

current conditions

Looks like a break this morning with partly cloudy skies and temperatures in the mid 20's. Yesterday's punishing winds have mellowed somewhat and are currently blowing 15-25 mph out of the west-southwest. The region picked up 8"-10" of snow from Thursday's storm, vastly improving the coverage. However, there's hardly any base and the riding and turning conditions are a bit of a wallowfest.

recent activity

The snowpack on the Skyline is spooky. We remotely triggered this 3' deep avalanche low on the slope, from a distance. The slide broke to weak, sugary snow near the ground. More can be found here.

Brett was in Pleasant Creek and put a great video synopsis together of his findings. Click here to view.

After channeling the ghost of Monte Atwater, our top notch observers Darce and Steve found some interesting conditions lower in the canyon. Click here to view.

The Manti-Skyline has some of the weakest snow in the state and the Thursday/Friday storm was the first notable event to test our fragile snowpacks strength. Unfortunately, it reminded me of my high school days... it failed miserably. We have a very dangerous setup on the Skyline right now because the snow won't be as tender as yesterday and it will allow us to get well out onto the slope before it fails and breaks to the ground. These are the type of avalanche conditions that lead to most avalanches accidents on the Skyline and today is no different. Steep, upper elevation, wind drifted slopes, especially those with an easterly component, need to be avoided. Once triggered, avalanches will break deep and wide, taking out the entire seasons snowpack, creating an unsurvivable slide.

It doesn't mean you can't ride. It does mean you need to stay off of and out from under steep wind drifted slopes, especially slopes facing the north half of the compass. Best to avoid being in avalanche terrain today. Stick to gentle, wind sheltered slopes and avoid being under or adjacent to slide paths. You can find good riding in the trees and low angle meadows.

Cornices have grown huge, especially on leeward ridges near the summit. These monsters can easily break back further than you might expect, taking you for a nasty, unexpected ride down the elevator shaft, and possibly triggering a large avalanche as you both hit the slope below..

weather

Warm and windy today with highs reaching into the upper 30's. Clouds and southwest wind increase late in the day as a strong cold front bears down on the state. The first of two pieces arrives late tonight with 2"-4" of snow expected and another, colder shot of snow slides through early Sunday with an additional 6". High pressure builds for early in the week.
