Forecast for the Uintas Area Mountains

Craig Gordon
Issued by Craig Gordon on
Saturday morning, December 26, 2020
In the wind zone, at and above treeline, CONSIDERABLE avalanche danger exists. Human triggered avalanches are LIKELY on steep, wind drifted slopes. Steep terrain facing the north half of the compass, and particularly slopes with an easterly component to its aspect are most suspect.
Mid elevations offer MODERATE avalanche danger on steep slopes facing the north half of the compass and human triggered avalanches are POSSIBLE.
In either case, shallow snow cover and low tide conditions barely hide natural obstacles like stumps and rocks, so, triggering even a small slide can lead to an instant buzz-kill and a season ending injury.
LOW avalanche danger is found on mid and low elevation slopes, particularly those facing south, but snow cover is super thin.

Special Announcements
Thanks for sharing your snow, your slope, and your stoke... well played!
A big shout out, high fives, and air hugs to the crew I met on Christmas Eve at Wolf Creek who not only brought an amazingly positive energy to the day.... you showed how to avoid avalanche danger by choosing the right terrain. In the image above, everyone opted to avoid the avalanche dragon on the steep, shady slope yet still had a great day on low angle terrain facing the south half of the compass, riding shallow pow, with their families, in the sun.
You know the program... roadside attractions are still an easy grab and just 'cause you can see it from the car doesn't mean it's safe or you're good to go. And remember, our front-line health care workers are maxed out. So, let's collectively think about our decisions and the consequences that may have on others.
Thanks to the generous support of our local resorts, Ski Utah, and Backcountry, discount lift tickets are now available. Support the UAC while you ski at the resorts this season. Tickets are available here.
Weather and Snow
Nowcast-
Late last night as Santa and Elvis exited the stadium, high clouds drifted into our zone ahead of a weak storm that'll clip northern Utah today. Temperatures cooled into the upper teens and low 20's overnight. Southwest winds blow in the mid 20's along the high peaks. No new snow to report since last weeks storm and total snow depths average just about two feet in depth, so the Uinta's are still quite thin and travel is sorta limited to road rides and grassy slopes.
Forecast-
Look for mostly cloudy skies with highs climbing into the low 30's. Southwest winds switch to the west late this afternoon and increase into the 40's and 50's. A quick hitting cold front slides through the area and snow develops as the day wares on. Not a big storm but we should see 2"-5" stack up by the time things wind down early Sunday morning.
Futurecast-
Clearing skies are on tap for Sunday, but the break is short lived as the next storm system sets its sights for the area Sunday night through Tuesday morning. This is looking like a better setup for us with a little more snow, water, and wind than previous storms. An active weather pattern is on tap for the upcoming week... stay tuned.

Avalanche Problem #1
Persistent Weak Layer
Type

Likelihood

Description
Nothing has changed with our problem child... a persistent weak layer of snow, now buried in the mid portion of our snowpack. And while last Tuesday's storm wasn't a dense, heavy, knock the entire house of cards over kind-of-snow, recent history tells us that every time we stack up additional snow or windload to our fragile snowpack, we see avalanches. So here's the setup. The current snowpack structure mirrors an upside-down cake... think, stronger snow on weaker snow. This type of layering leads to tricky avalanche conditions because there's not widespread, in-your-face, natural avalanche activity. Rather, our snowpack needs a trigger like us to roll along and knock the legs out from underneath. And yes... we can trigger slides from a distance or from adjacent slopes, and this is the type of avalanche dragon where we can pull the entire log pile down on top of us, even if we're playing on low angle terrain. All we need is to be connected to steep terrain above us. And once triggered, today's avalanches may break wider and deeper than you might expect.
But you don't have to ride blind... so, tweak small test slopes like the one in the image above, looking for and listening to signs of unstable snow like whoomping sounds and sudden collapses of the snowpack or shooting cracks in front of your skis, board, or sled. And of course the biggest clue of all... recent avalanches, especially on the same types of slopes you wanna ride on.
Avalanche Problem #2
Wind Drifted Snow

Description
There's not an abundance of snow available to blow around, but the Uinta's are a big place and I bet if you were looking for a fresh wind drift, you could stumble across one. Found mostly on the leeward side of upper elevation ridges, this afternoon's strong winds, may drift snow lower downslope than you might expect, as well as cross-loaded terrain like chutes and gullies. In either case, it's an easy and mostly manageable avalanche problem to avoid by simply steering clear of any fat, rounded piece of snow, particularly if it sounds hollow like a drum. And remember... our snowpack is super shallow and triggering even a small slide can take you for a body-bruising ride through rocks and stumps barely hidden under the thin snowpack.
Additional Information
Last Friday I rolled up to a fresh avalanche and found Utah Snowmobile Association president, Cal Taylor, investigating the slide and performing a mock rescue with his riding partner Mike Davis. In the video above, Cal has some sage advice for our riding community.
I'll update this forecast by 7:00 AM tomorrow, Sunday December 27th.
