Forecast for the Uintas Area Mountains

HEADS UP.... the storm might be over, but avalanche danger remains sketchy. These are the exact conditions were we see most avalanche accidents and fatalities occur.
At mid and upper elevations, especially on steep wind drifted slopes facing the north half of the compass the avalanche danger is CONSIDERABLE. HUMAN TRIGGERED AVALANCHES ARE LIKELY AND NATURAL AVALANCHES POSSIBLE. ANY AVALANCHE BREAKING INTO OLD SNOW WILL HAVE SERIOUS CONSEQUENCES.

Special Announcements
We are very proud to introduce our new website for the 2018-19 winter season. This will provide an easier and cleaner way to view all of the snow and avalanche information that you've come to rely on. We are quite happy with how the new website performs on mobile devices as well. We think you'll find the desktop or laptop experience pleasant as well. We are still tying up some loose ends so bear with us.
Weather and Snow
Wow... what a storm! Yesterday's snow stacked up fast and furiously with an evenly distributed 15" of snow and about an inch and a half of water across the range. Storm totals since Thursday are just over two feet! In the wake of the big holiday storm, skies cleared overnight and temperatures crashed into the single digits. Yesterday's cow-tipping southerly winds have diminished significantly and currently blow west and northwest 10-20 mph along the high ridges. While the storm has turned much of our landscape white, riding and turning options are still limited. Low angle, rock free grassy slopes, meadow skipping, or road rides are gonna be your best bet today.
Our main man Ted Scroggin has been out and about, stomping around Bald Mountain Pass and in Whitney Basin since early November. He reports a layered snowpack with a few crust/facet sandwiches and very weak snow near the ground on mid and upper elevation, north facing slopes.
This is exactly the type of terrain that's gonna continue to be sketchy today.
Wanna avoid avalanche danger this weekend? Of course you do and it's easy. Simply steer clear of any mid or upper elevation slope that has pre-existing, early season snow.
Your exit strategy is to swing around to south facing terrain which has no old snow and you can ride without the worry of avalanches breaking to weak snow near the ground.
Michael J stomped around the south face of Hoyt Peak yesterday and found lots of new storm snow resting on warm ground that was bare and brown prior to the thanksgiving storm... now that's the ticket!
Recent Avalanches
Yesterday, backcountry travelers were finding widespread collapsing, shooting cracks, and easily triggered soft slabs on road cuts and steep, leeward slopes facing the north half of the compass.

Description
This was a much needed storm for the range and in most locations we doubled our snowpack in the past 48 hours. So the good news is... we finally have some terrain to ride. The bad news... terrain choices are still very limited and the deepest snow is found on mid and upper elevation slopes facing the north half of the compass. Unfortunately, that's exactly the type of terrain that harbors weak snow near the ground and that's exactly where we could trigger an avalanche that breaks deeper and wider than we might expect. The end result is an unmanageable slide that gets quickly out of hand as it reveals a myriad of hidden obstacles like stumps and rocks that will easily ruin your day or end your season.
Fortunately we have choices and if you want to avoid today's avalanche dragon, you simply avoid mid and upper elevation terrain, particularly slopes facing the north half of the compass where the snowpack is weak and sugary.
Mirror Lake Highway and Wolf Creek Pass are still open, but just 'cause you can see your rig parked on Bald Mountain Pass or near Wolf Creek, doesn't mean the terrain you're choosing to ride is good to go.
Remember- this is the time of year where most of us get tricked thinking there isn't enough snow to avalanche. However, this is also the type of setup when most close calls and accidents occur. If you are getting out and about, be prepared for your own self rescue. Wear and know how to use an avalanche beacon, shovel, and probe.
Ted was out and about near Murdock Bowl and found the snow structure setup in the image above, noting he couldn't even isolate the column of snow before it failed to the weak, midpack facets.... spooky. Click HERE to see his take on things and view a short viddy.
Avalanche Problem #2
Wind Drifted Snow
Type
Location
Likelihood
Size
Description
Winds were all over the map during the storm and I expect we'll find both old and new drifts reactive to our additional weight, even at lower elevations. Today you'll want to continue avoiding steep, wind drifted slopes especially if they look fat and rounded or sound hollow like a drum.
Additional Information
After a cold start a warming trend with mostly sunny skies is expected into mid week as high pressure builds in. Several disturbances bring the snow back into the picture Wednesday into next weekend.

If you're getting out and about, please let me know what you're seeing especially if you see or trigger and avalanche. I can be reached at [email protected] or 801-231-2170
It's also a good time to set up one of our very popular avalanche awareness classes. Reach out to me and I'll make it happen.
