Forecast for the Uintas Area Mountains

Craig Gordon
Issued by Craig Gordon for
Tuesday, November 27, 2018
In the wind zone 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 ON ANY SLOPE HARBORING OLD SNOW NEAR THE GROUND. AND REMEMBER- ANY SLIDE BREAKING INTO OLD SNOW WILL HAVE SERIOUS CONSEQUENCES.
Lose the old snow... you lose the problem and the avalanche danger drops dramatically.

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
The big holiday storm delivered equal amounts of white goodness across the range, dumping over two feet of much needed snow with about 2" of water. High pressure is shifting east this morning allowing a series of progressively stronger storms to enter the region. Currently, under mostly cloudy skies temperatures are in the teens and low 20's. Westerly winds blow 15-25 mph along the high peaks. We can expect light snow showers later today with highs reaching into the upper 30's. Westerly winds bump into the 40's along the high ridges by about dinner time. Today's little storm brings a couple inches of snow.
We are working to get the Uinta weather network back online. In the meantime, above is 24 hour data from Trail Lake (9945')
Images above are prior to the big Thanksgiving storm, giving you a sense of the type of terrain where today's avalanche dragon lives. While the storm 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.
Wanna avoid avalanche danger today? 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 slopes or lower elevation terrain which had no old snow prior to the big storm and you can ride without the worry of avalanches breaking to weak snow near the ground.
Recent Avalanches
Yesterday, backcountry riders continued to report widespread collapsing, loud booming whoomphs, and shooting cracks like in Michael J's image above... all signs of unstable snow.

Description
The big storm was good to the eastern front, delivering a healthy dose of snow and water. In most locations we doubled our total snowpack since Thanksgiving Day. So the good news is... we finally have some terrain to ride. The bad news... terrain choices for riding 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 still 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.
While I feel like the snowpack is adjusting to the big storm, I'm not sold on just rolling the dice and taking my chances on theory... there's just too many variables. So, I'm playing it safe with conservative terrain choices and by riding slopes that had no old snow prior to the big storm.
Plowing is done on Mirror Lake Highway, but Wolf Creek Pass is still open. However, just 'cause you can see your rig parked 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.
Additional Information
Looks like a few storms in the queue. A stronger but warmer system will cross the region Thursday afternoon into early Friday, with a colder system expected for the weekend.
