Forecast for the Uintas Area Mountains

Saturday, December 11, 2021
Heads up... the recent storm changed the landscape and bumped the avalanche danger up a few notches.
A MODERATE avalanche danger is found on upper elevation terrain facing the north half of the compass and human triggered avalanches are possible, especially on steep wind drifted slopes and particularly those that harbor old October snow. And remember... any avalanche that fails on older snow may break deeper and wider than you might expect, revealing a myriad of season ending obstacles. But here's the good news, simply switch aspect and set your sights on terrain that was bare prior to yesterday's big storm. You'll find generally LOW avalanche danger on slopes facing the south half of the compass.

Considerable

Weather and Snow
NOWCAST-
And then it snowed... in fact, it dumped! Yesterday's big storm fully delivered a solid 12" of snow with an 1" of water near the trailheads and closer to 16" in the high country. Skies are slow to clear, so temperatures decided to take the lead, cratering into the single digits and negative territory overnight. Combine this frigid air with west and southwest winds blowing in the 20's and you've got windchill factors registering to -25 degrees along the high peaks... ouch! Riding and turning options went from zero to hero in just 48 hours, but with total snow depths hovering right around 24" it's still thin out there. Road rides and rock free, low angle meadows are the ticket.
FORECAST-
Look for partly cloudy skies with high temperatures creeping out the deep freeze and into the low 20's. West and southwest winds blow in the 20's along the ridges and bump into the 30's near the high peaks. Overnight lows crash to near zero.
FUTURECAST-
The flow gradually turns southwesterly tonight through Tuesday morning, bringing a gradual warming the next few days. Brief, light snow showers are possible from Sunday into Monday morning. Another storm is slated for midweek.

Description
Above is a 24 hour data dump from Windy Peak, 10,662' in elevation, showing yesterday's timeframe when sensitive drifts formed along the leeward side of upper elevation ridges.
The recent storm delivered a good thump to the snowpack and I suspect steep, northerly terrain that held weak, old October snow came to life and produced small, natural avalanches. Steep, shady slopes that didn't avalanche wait for a trigger like us to roll along and tip the scales. So, this is exactly the type of terrain we want to avoid. And while the snowpack settled somewhat and gained some strength overnight, given the current "stronger snow on top of weaker snow" structure, I bet you can still trigger avalanches from a distance or from adjacent slopes. You don't have to dive too deep into the avalanche tool box or get too technical in order to get a handle on current conditions. Tweak small test slopes that are similar to the type of terrain you wanna ride and see how they're reacting to your additional weight. Look for clues to unstable snow like shooting cracks, whoomping sounds, and of course the biggest clue to avalanches... avalanches!
Now here's where it gets complex... there's a fresh blanket of snow coating our mountains and everything's gonna look white. In fact, it'll be more difficult to determine what slopes held early season snow. But remember... terrain that faces the south half of the compass was bare prior to yesterday's storm. And while there's plenty of gear wrecking rocks and stumps to slam into, there's no old snow and avalanche issues are straight-forward.
And remember- a few of our high mountain passes dump us off in avalanche terrain. I think about early season roadside attractions like Wolf Creek Bowl near Highway 35 and Wolf Creek Pass. Easy grab... right? However, just 'cause you can see it from the road doesn't means it's good to go.
