Avalanche Advisory
Advisory: Uintas Area Mountains Issued by Craig Gordon for Wednesday - December 2, 2015 - 4:23am
bottom line

In general most terrain throughout the range offers a LOW avalanche danger.

However, at and above treeline, the avalanche danger is MODERATE. While pockety at best, human triggered avalanches are possible, on steep, wind drifted slopes facing the north half of the compass.




current conditions

Skies are clear and temperatures a little inverted, climbing into the upper teens and low 20's along the ridges overnight. Trailhead temperatures are still in the single digits. Around midnight, winds switched to the west-southwest and are currently blowing 10-20 mph along the high peaks. The Uinta's are boney and in general you gotta stick to road rides or low angle grassy meadows. If there's a lump in the snow, chances are there's a sled wrecking rock hidden underneath... tread lightly! Our western Uinta weather station network is up and running.

The range is white from far...

description

The Uinta's are super thin right now and our snowpack is losing strength. Since I generally have a glass half full kinda outlook, I'd say our snowpack is more structurally challenged rather than weak. However, I can't deny the fact that we've got issues and once it snows or if the wind starts to crank, we'll see avalanches.... and this is why. The snowpack is comprised of sugary facets near the ground, with a couple of mid-pack crusts of varying thickness and strength, topped off with 6" of light density snow in protected areas, and in more wind exposed terrain, a supportable wind slab. For right now, the avalanche danger is pretty straight-forward and a few fresh drifts along the leeward side of upper elevation ridges is today's main avalanche concern. Remember- even a shallow slide can take you for a nasty ride through rocks and stumps barely hidden under our shallow snowpack.

As usual, JG submitted a great write up of his travels and his snowpit diagram illustrates the overall structure.

Snow depths in our travels were a bit more on the shallow side.

In either case, the snow near the ground continues to lose strength.

weather

High pressure brings dry and warm weather the next couple days, with a few clouds drifting into the range late in the day. Highs climb into the low 30's with overnight lows dipping into the upper teens. Winds ramp up from the southwest on Thursday and Thursday night ahead of the next storm system. This relatively weak storm moves through northern Utah on Friday and Friday night. High pressure builds through the weekend with a hint of a storm around midweek.
