Avalanche Advisory
Advisory: Uintas Area Mountains Issued by Craig Gordon for Sunday - February 21, 2016 - 4:35am
bottom line

In the wind zone, at and above treeline, a MODERATE avalanche danger exists and human triggered slides are possible on steep, wind drifted slopes. While it's becoming more the exception than the rule, any avalanche that breaks to weak, sugary snow near the ground, has the potential to be deep and dangerous.




current conditions

Under clearing skies and a brilliant, larger than life moon, high pressure is building in the wake of yesterday's little system that delivered a couple inches of snow to region. Westerly winds are blowing 15-25 mph along the high peaks and temperatures are 10 degrees cooler than yesterday at this time, currently registering in the upper teens and low 20's. Amid all the old tracks, suncrusts, and wind funk, with a little creative hunting you'll still find soft settled snow in wind sheltered, shady terrain.

JG kills it with his pit profiles. Here you can clearly see our current snowpack setup. More on his Friday travels are found here.

Heads up! Thursday's ferocious winds toppled trees throughout the range. Probably a good idea to have a saw handy in case you find yourself dead-ended in the woods.

Trip reports and observations are found here.

recent activity

A few shallow, yet very manageable fresh drifts were noted along the leeward side of upper elevation ridges.

Yesterday's west and southwest winds blew in the 40's and 50's along the high peaks, and had no problem finding enough loose snow to whip into fresh drifts, sensitive to the additional weight of a rider. Manageable in size and predictably breaking at or below your skis, board, or sled, I think this will be the theme again today. The good news is, this is a pretty straight-forward avalanche problem, because if you lose a little elevation... you'll lose the problem.

Ted stomped around Double Hill yesterday and found winds rapidly forming drifts along the leeward side of upper elevation ridges. More on his travels here.

It's been a week since we've seen or heard of any avalanche activity breaking to weak snow near the ground. As a matter of fact, the last reported deep slab avalanche was in Race Track Bowl on February 13th... more details here . While most of our terrain is turning the corner towards a homogenous, predictable snowpack, there's still isolated areas where strong, solid feeling snow rests on top of weak, sugary snow near the ground. Of course, our usual suspects come to mind, in particular, steep rocky terrain and slopes that previously avalanched during the Solstice Storm and have remained shallow all season. It's not full on green light conditions out there today and I'd continue to carefully evaluate any steep slope with these characteristics.

weather

Mostly sunny skies, westerly winds blowing 10-20 mph along the ridges, and cool temperatures are on tap for us today. Highs reach into the low 30's with overnight lows bottoming out in the upper teens. Clouds increase late tonight and a more promising looking shot of snow moves into the area Monday. It's not a big storm, perhaps 3"-6" by Tuesday morning, and then high pressure builds for Wednesday through the end of the work week.
