Forecast for the Uintas Area Mountains

Heads up, nothing has changed... it's the real deal. Please think about your terrain choices and the potentially deadly consequences of triggering an avalanche today-
Very dangerous avalanche conditions exist near and above treeline in the western Uinta's where the avalanche danger is HIGH. Both natural and human-triggered avalanches are likely. Very dense, heavy snow combined with strong winds has overloaded our fragile snowpack. Below treeline, human triggered avalanches are likely, and the avalanche danger is CONSIDERABLE.
Here's your exit strategy- there's plenty of safe, low angle terrain, but the key to avoiding avalanches is to avoid being on, under, or anywhere near slopes steeper than 30 degrees, especially those facing the north half of the compass.

Avalanche Warning
THE AVALANCHE DANGER IS HIGH WITH DANGEROUS AVALANCHE CONDITIONS.
AN AVALANCHE WARNING CONTINUES FOR THE MOUNTAINS OF MUCH OF THE STATE OF UTAH, INCLUDING THE WASATCH RANGE...BEAR RIVER RANGE...UINTA MOUNTAINS...AND THE MANTI-SKYLINE.
HEAVY DENSE SNOWFALL AND STRONG WINDS HAVE CREATED DANGEROUS AVALANCHE CONDITIONS. BOTH HUMAN TRIGGERED AND NATURAL AVALANCHES ARE LIKELY. STAY OFF OF AND OUT FROM UNDER SLOPES STEEPER THAN 30 DEGREES
Weather and Snow
NOWCAST-
Under mostly cloudy skies, snow showers linger in the wake of yesterday's storm that delivered an evenly distributed 6" of low density snow across the range. Snow totals since Sunday add up to nearly two feet from the North Slope to Trial Lake with half that amount the further south you travel towards Mill Hollow and Currant Creek. Winds relaxed somewhat around dinnertime, switched to the west and have been blowing 25-35 mph along the peaks. It's cold out there with temperatures cratering into the singles overnight at most locations and negative territory along the ridges. Windchill factors clock in at -30 degrees. If you brave the cold you'll be rewarded with over-the-head and over-the-hood riding conditions.
FORECAST-
Expect scattered snow showers throughout the day with little accumulation. West and southwest winds blow 20-30 mph along the ridges. High temperatures barely crack into the teens and overnight lows crash into negative territory.
FUTURECAST-
On and off snow showers through Wednesday with another good shot of snow developing for the end of the work week.

Recent Avalanches
With a little thump, this piece of snow in steep, rocky terrain facing the north half of the compass, was remotely triggered from a distance. Not the biggest or the deepest, but the structure says it all. Avalanches are finding the weakest link and breaking to the ground.

Description
Don't get fooled by today's, in-your-face, low density snow. Sure, the snowpack will feel solid. In fact, it's gonna feel strong and bomber under our skis, board, or sled. However, we need to think not only about the snow we're riding in, but also the snow we're riding on and the basement layer is a house of cards and needs some time to adjust from the recent round of snow, water, and wind. Slopes that haven't already avalanched naturally, just wait for a trigger like us to roll along and knock the legs out from underneath it. Today's avalanche danger is nothing to toy with as any avalanche triggered may have deadly consequences. Once triggered, slab avalanches will break on a persistent weak layer of old snow near the ground, resulting in a deep, wide, unmanageable slide.
  • Avalanches will break up to 6 feet deep and hundreds of feet wide in heavily wind loaded areas.
  • You don't have to be on a steep slope to trigger a large, dangerous avalanche.
  • Avalanches can be triggered from a distance, even on flat terrain.
  • You need to stay off of and out from under steep slopes.
Here's your exit strategy- there's plenty of safe, low angle terrain in the Uinta Mountains. But the key to avoiding avalanches is to avoid being on, under, or anywhere near slopes steeper than 30 degrees, especially those facing the north half of the compass.
Avalanche Problem #2
Wind Drifted Snow

Description
Above is a 24 hour data dump from Windy Peak (10,662')
Winds are always the great equalizer on the eastern front and man... they've been relentless for days. West and southwest winds have cranked 30-40 mph since last Thursday, blasting into the 70's at times, and just recently, blowing in the 50's and 60's for a good portion of yesterday morning. With no shortage of snow to blow around, fresh drifts have formed everywhere, particularly in terrain that harbors a persistent weak layer of sugary facets near the ground. Today you need to avoid any fat, rounded, hollow sounding wind drift because that's exactly the right recipe for avalanches to break deeper and wider than you might expect, especially on steep, shady slopes.
