Avalanche Advisory
Advisory: Uintas Area Mountains Issued by Craig Gordon for Wednesday - February 26, 2014 - 5:56am
bottom line

In the wind zone at upper elevations, the avalanche danger is CONSIDERABLE today. Human triggered avalanches are probable on all steep, wind drifted slopes, particularly those facing the north half of the compass and especially those with an easterly component to their aspect. Once triggered, today's avalanches can break deep and wide, creating a very dangerous slide.

A MODERATE avalanche danger is found at mid elevations and human triggered avalanches are possible on steep, wind drifted slopes.

LOW avalanche danger is found on gentle slopes with no steep terrain above or adjacent to where you're riding.

current conditions

Skies are clear and winds have finally subsided, blowing a more reasonable 10-20 mph along the high peaks. Temperatures are mild, in the low 30's at the trailheads and mid to upper 20's along the ridges. Low elevation terrain has taken on a lot of heat recently, leaving a wide variety of breakable crusts which soften during the heat of the day. If you're looking for powder head to wind sheltered, mid and upper elevation terrain where you'll find soft, creamy snow, on a go anywhere kinda base.

Spring has sprung and the moose is loose! A couple of my vegan brethren enjoying an afternoon by the river, munching on willows and soaking in the warm temperatures.

recent activity

Avalanche are still breaking to the ground. This slide was triggered in Upper Weber Canyon yesterday. 8' deep, 300' wide, running 400' vertically, failing on weak, sugary snow.

The good news is... the snowpack is slowly gaining strength and the chance of triggering a big, deep, scary avalanche is diminishing somewhat. As a matter of fact you can ride plenty of slopes across the range and be good to go and therein lays the bad news. The snow structure remains questionable, especially in steep, rocky terrain facing the north half of the compass. While the surface snow feels strong and solid underneath us, it's the bad mojo near the ground that's the big red flag. Strong snow over weak snow often suggests false green light conditions, allowing us to get well out onto the slope or put several sets of tracks on the hill before we find a weakness, collapse the slope, and now all bets are off. Cornice drops and slope cuts are ineffective ways to test the stability of a slope. Best way to deal with this type of avalanche dragon is with terrain management. Steep, rocky, leeward terrain remains suspect and should be avoided.

Remember- there are plenty of days left this season to get after it. Right now we have to exercise some patience.

Cornices have grown quite large and will break back further than you might expect. You'll definitely want to give these boxcar sized monsters the respect they deserve.
weather

A beautiful day is on tap with mostly sunny skies and temperatures soaring into the low 40's. West winds remain reasonable, blowing in the teens and low 20's. Clouds thicken throughout the day and a few scattered snow showers are possible around sunset, Moisture increases Thursday and a quick hitting storm delivers 4"-8" of snow by late Thursday night. A break in the action for Friday, then a moist unsettled pattern is slated for the weekend.
