Forecast for the Uintas Area Mountains

Craig Gordon
Issued by Craig Gordon for
Saturday, December 31, 2016

Making up a small portion of the terrain available to ride in, pockets of MODERATE avalanche danger exist today. In the wind zone, at and above treeline, human triggered avalanches are POSSIBLE on steep, wind drifted slopes, especially those with an easterly component to their aspect.

Out of the wind, our snowpack is well behaved and predictable and the avalanche danger is LOW

Weather and Snow

High pressure remains in control of our weather pattern for another day and that of course means valley gunk and fresh clean air in the mountains. Currently, temperatures are in the low to mid teens at most of our remote weather sites and winds are generally westerly, blowing 10-20 mph along the high ridges. Some of our big, open, upper elevation bowls took a hard hit from Tuesdays wind, but lose a little elevation and you'll be treated to premium riding and turning conditions.

Ted was in the Moffit Basin yesterday and noted that riders are taking advantage of mostly stable snow and getting into some big terrain without incident. (Scroggin photo) More on his travels found here.

Recent Avalanches


This rider initiated pocket, just underneath the cornice seen in the images above, was about 18" deep x 20' wide. It was triggered yesterday on a steep, upper elevation, east facing, wind drifted slope in Upper Weber Canyon. (C. Brown photo)

Avalanche Problem #1
Wind Drifted Snow

Likelihood
Size
Description

While not particularly connected and making up a small portion of the terrain available to ride in, pockety wind drifts sensitive to our additional weight can still be found on steep, leeward slopes in the wind zone. A bit less sensitive than previous days, recent drifts could none-the-less break a little deeper and wider than you might expect. I'd continue to avoid any fat, rounded piece of snow, especially if it sounds hollow like a drum.


A quick visual scan of the ridges and terrain features like chutes and gullies, can help you determine where the wind's been blowing and the type of terrain you wanna avoid.

Persistent Weak Layer

Likelihood
Size
Description

Overall our snowpack looks great and most slopes across the range are comfortable in their own skin. However, we do have a few problem children and terrain where the snowpack has remained thin all season, particularly steep, rocky, upper elevation slopes facing the north half of the compass should be considered suspect. Once triggered, an avalanche in terrain with these characteristics can easily get out of hand. If you're getting into the big north facing bowls, think about the consequences of triggering an avalanche that breaks to weak layers near the ground and at the very least, have an exit strategy.

When I think of a place that harbors weak snow and the potential to trigger a deep, dangerous avalanche, Currant Creek Peak always comes to mind. We took a spin out there Tuesday and found mostly supportable snow and a solid snowpack. But with all the great riding options available, there's no reason to tease this slope and roll the dice... this is exactly the type of complex terrain I'd steer clear of.

Additional Information

A storm system diving to the south, ushers in a few clouds for our region, but in general it's gonna be another beautiful day in the mountains. High temperatures bump into the low to mid 30's with overnight lows in the teens. Westerly winds blow in the 20's along the high ridges, but switch to the south on Sunday and increase ahead of an approaching storm system that slides through northern Utah Sunday night into Monday morning. An unsettled weather pattern continues for much of the upcoming week.
