Highlights

The western Uinta's are sketchy... once triggered, today's avalanches will break deeper and wider than you might expect, resulting in a dangerous slide with severe consequences.

In the wind zone, at and above treeline, you'll find CONSIDERABLE avalanche danger. Human triggered avalanches are LIKELY on steep, wind drifted slopes. Steep terrain facing the north half of the compass, and particularly slopes with an easterlycomponent to its aspect are most suspect and should be avoided.

Mid elevation slopes offer MODERATE avalanche danger and human triggered avalanches are POSSIBLE on steep, shady slopes.

Here's your exit strategy-

LOW avalanche danger is found on low elevation slopes, particularly those facing south, but snow cover is super thin.

    Recent wind drifts settled and gained strength the past few days and won't be quite as widespread or touchy today. But as we know, the Uinta's are a big place and the ticket is to avoid pulling on the dogs tail. Steer clear of steep wind drifted slopes and terrain features like chutes and gullies which appear fat and rounded or sound 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.

    The writing is on the wall and it's pretty clear... as a matter of fact, red flags continued waving in our faces yesterday. Booming collapses, shooting cracks, and the biggest sign of avalanches.... AVALANCHES!

    So here's the deal- the snowpack is complex, we have a persistent weak layer in the mid portion of the pack, and this fragile structure experienced a rapid change earlier in the week when Tuesday's storm slammed down on. Our snowpack needs a little time to get comfortable in its own skin.

    Many slopes hang in the balance waiting for a trigger like us to roll along and knock the legs out from underneath. This is the setup where the wheels come off the bus because we can trigger slides from the flats, low on the slope, from a distance, or from adjacent slopes. We don't need to be on the slope... just connected to it.

    This is the kind of avalanche dragon where we pull the entire log pile down on top of us, even if we're playing on low angle terrain.

    But you don't have to ride blind... so, tweak small test slopes, 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.

Special Announcement

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.

Recent Activity

From yesterday, this slide in Humpy Basin on an upper elevation northeast facing slope, was triggered lower downslope than you might expect. Breaking 18"-24" deep and 200' wide, in a steep rocky section where the snowpack is slightly shallower and weaker... this is the type of avalanche you could still trigger today.

Our main man, Ted Scroggin, took a rip around Mirror Lake Highway Wednesday and found plenty of signs of unstable snow including small avalanches just off the freshly groomed road. Ted knows the Uinta's better than anyone. His insight, trip report, and sage knowledge is found here.

Remember.... solid decision making is paramount because 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.

Snow and Weather

Nowcast-

Skies are clear, temperatures in the single digits, and westerly winds blow 10-20 mph along the high peaks. Tuesday's storm delivered a solid 10" of medium density snow and conditions look more encouraging out there as average snow depths creep into the three foot range. And while things slowly improve, it's still low tide in the Uinta's and travel is sorta limited to road rides and grassy slopes.

Forecast-

Mostly sunny this morning with high clouds drifting into the area as the day progresses. Westerly winds bump into the mid 20's and high temperatures climb into the low 30's.

Futurecast-

A weak, quick hitting storm slides through the region late tonight, delivering 2"-4" of snow. High pressure builds Saturday with no big storms in sight.

Additional Info

A few weeks ago, Mark Staples teamed up and Ski-Doo athlete Steve Martin, and they had a great and very informative ride in the Whitney Basin. Whilst out and about, they remotely triggered a small slide on the way to investigating a large, moose triggered avalanche. In the viddy above they've got some great advice on how to ride when avalanche danger is elevated and snow depths lean.

I'll update this forecast by 7:00 AM tomorrow, Saturday January 9th.
