Avalanche Advisory
Advisory: Uintas Area Mountains Issued by Craig Gordon for Saturday - January 11, 2014 - 5:13am
bottom line

This is the real deal. We're talking... tree snapping, bone crushing, we're not coming home to our families at the end of the day kind of avalanches.

Terrain to avoid- steep, upper elevation slopes facing the north half of the compass, especially those in the wind zone with an easterly component to their aspect, where a HIGH avalanche danger exists. Both human triggered and natural avalanches are likely.

Go to terrain- If you're looking for LOW avalanche danger, head to wind sheltered terrain, especially those facing the south half of the compass where there are no steep slopes above or adjacent to where you're riding.
avalanche warning

THIS AVALANCHE WARNING IS FOR THE MOUNTAINS OF NORTHERN AND CENTRAL UTAH, TO INCLUDE THE WESTERN UINTA MOUNTAINS. VERY DANGEROUS AVALANCHE CONDITIONS EXIST THROUGH THE WEEKEND...AVOID BEING ON OR BENEATH STEEP MOUNTAIN SLOPES...AS AVALANCHES MAY BE TRIGGERED LOW ON THE SLOPE AS WELL.
current conditions

Under partly cloudy skies, there's a break in the action this morning as the next potent system sets its sights on the region. Yesterday's punishing winds have mellowed somewhat and are currently blowing 15-25 mph out of the west-southwest. Temperatures are in the mid 20's and upper teens along the ridges. There's a lot of wind-jacked snow out there, but low angle, wind sheltered terrain with no steep slopes above or adjacent to where you're riding is the place to be.

recent activity

There was a brief window of visibility yesterday allowing for a view of some pretty spectacular slides.

Thanks to JG for these great photos of this monster, natural slide, on a heavily wind loaded east facing slope in Smith-Moorehouse. More on his obs from that area here.

description

Yesterday's raging west winds were the great equalizer and the weak pre-existing snowpack was no match for the rapid wind loading. Fresh slabs formed everywhere, even getting down into terrain we normally consider sheltered. While the region most likely experienced a significant avalanche cycle, I think many slopes lay in the balance, suspended in time, just waiting for a trigger like us to come along and knock the legs out from underneath.

Make no mistake... our snowpack is sketchy and avalanche conditions are deceptively dangerous.This is the type of setup where most avalanche accidents happen in the western Uinta's because the snowpack will feel solid and strong underneath us. Complicating matters is the fact that you can trigger avalanches low on the slope or from a distance. Once initiated, today's slides will break deep and wide, creating an unsurvivable avalanche.

It doesn't mean you can't ride. It does mean you need to stay off of and out from under steep wind drifted slopes, especially slopes facing the north half of the compass.
weather

Partly cloudy skies, warm temperatures, and increasing southwest winds are on tap this morning. Highs reach into the mid to upper 30's and southwest winds start cranking into the 30's and 40's by days end. It looks like there are two pieces to the next storm system. The first shot moves in late tonight, the second arrives early Sunday. 12"-18" of snow is a good bet. A cold moist and unstable flow prevails Sunday into Sunday night.
