Forecast for the Uintas Area Mountains

Craig Gordon
Issued by Craig Gordon on
Friday morning, December 20, 2019
Any avalanche that breaks to old snow near the ground WILL quickly get out of hand, resulting in a deep, dangerous slide.
UNPREDICTABLE and UNMANAGEABLE-
Making up a small portion of the terrain available to ride in today, in the wind zone at upper elevations, pockets of CONSIDERABLE avalanche danger are found on steep slopes facing the north half of the compass, especially those with an easterly component to their aspect. Human triggered avalanches are LIKELY, particularly in rocky terrain harboring weak, pre-existing, early season snow near the ground.
MORE PREDICTABLE-
New and old wind drifts are most prevalent along the leeward side of upper elevation ridges and around terrain features like chutes and gullies where MODERATE avalanche danger is found and human triggered avalanches are POSSIBLE.
Here's your exit strategy-
Wind sheltered, low and mid elevation terrain and big open meadows with no steep slopes above or adjacent to where you're riding generally offers LOW avalanche danger and human triggered avalanches are unlikely.

Special Announcements
Huge thanks to Park City Professional Patrol Association for hosting last nights avalanche awareness discussion and thanks to everyone who came out to visit. I look forward to all of us having a safe season and to seeing y'all on the snow.
It is with a heavy heart that I report a tragic, backcountry avalanche accident which occurred Sunday in the Dutch Draw area along the Park City/Big Cottonwood Canyon ridge-line. Of course, our collective thoughts, prayers, and energy go out to the friends and family of Raymond M. Tauszik, 45, of Salt Lake City.
A full report is found here.
Weather and Snow
Currently-
Skies are clear, temperatures in the teens, and west-northwest winds blow 15-25 mph along the high peaks. No new snow has fallen for a week, but with total snow depths averaging just over three feet, the range has excellent early season coverage. Riding and turning conditions are quite good and low angle, wind sheltered slopes are the ticket.
For today-
A stunning day is on tap today. Expect bright sunshine with temperatures climbing into the mid 30's and dipping into the teens overnight. Northwest winds remain reasonable today, blowing 15-25 mph along the high ridges.
Future cast-
High pressure builds over the region today and remains in place through Saturday. High clouds increase Saturday and Sunday along with increasingly strong southwest winds for Sunday. Weather becomes more active beginning on Christmas Eve
Recent Avalanches
Ted was near Double Hill Wednesday and spotted this connected hard slab on a heavily wind loaded, northeast facing slope on the north end of Double Hill. Breaking 3'-5' deep and about 150' wide, this avalanche failed on weak, sugary snow near the ground. The jury is still out, but nearby sled tracks suggest this slide was triggered from a distance. Ted knows the Uinta's better than anyone and he's an integral part of our avalanche forecast team. Ted's insight and very informative report is found here.

Description
The snowpack continues gaining strength and stability tests suggest the pack is getting comfortable in its own skin. However, Wednesday's avalanche on Double Hill clearly shows we're not out of the woods just yet. So here's where we need to take a minute, step back, and evaluate our objectives, because we're seeing the biggest clue to avalanches.... and that's other avalanches! I realize the range is white and the snowpack is gonna feel really strong and supportable under our skis, board, or sled. However, we've gotta think not only about the snow we're riding in, but also the snow we're riding on and right now we're still seeing avalanches fail on weak, early season snow. Once triggered, avalanches can break deep and wide, especially on steep, upper elevation wind drifted slopes, resulting in a deep, dangerous slide. No matter how you cut it, this is not the type of avalanche problem that we want to tangle with or try to outsmart... patience and avoidance are the only solution. I'm simply gonna ride low angle terrain in the sun and avoid being on or under steep, wind drifted slopes.
There's a lot of terrain to ride today and not have to deal with unmanageable avalanche conditions, IF you chose slopes that had NO old snow prior to the big Thanksgiving storm.
Avalanche Problem #2
Wind Drifted Snow
Type
Location
Likelihood
Size
Description
A few old wind drifts linger along the leeward side of upper elevation ridges and around terrain features like chutes and gullies. Most are stubborn and not particularly sensitive to our additional weight, but remember- winds cranked during last weeks big storm, drifting snow in unusual locations and further downslope than we usually see. So, your best bet for avoidance is to simply steer clear of any fat, rounded piece of snow, especially if it looks chalky or sounds hollow like a drum. In addition, look for and listen to clues like whoomphing sounds or shooting cracks in the snow which are sure signs of unstable conditions.
