Avalanche Advisory
Advisory: Uintas Area Mountains Issued by Craig Gordon for Friday - February 26, 2016 - 5:03am
bottom line

While the avalanche danger is generally LOW, pockets of MODERATE avalanche danger exist on steep, upper elevation, leeward slopes, especially those facing the north half of the compass. Yes... it's becoming more the exception than the rule, but any avalanche that fails on weak, sugary snow near the ground, has the potential to break deeper and wider than you might expect.

The danger of wet sluffs and slides increases to MODERATE on steep sunny slopes and human triggered avalanches are possible with daytime heating.

current conditions

Skies are clear, winds light and variable, and temperatures in the upper teens and low 20's. Lower elevation sunny slopes are yeilding an early crop of supportable corn, but the higher you go in elevation, the less reliable the crust becomes. If you're looking for a sure bet, simply flip over to the north half of the compass and you'll still find soft, settled powder on a go-anywhere base.

recent activity

Ted was in Gold Hill Basin Wednesday and discovered this sled triggered slab from Saturday. Breaking 150' wide and failing on weak snow near the ground, check out Ted's great write-up and very informative video here.

A few old wind drifts are found on steep leeward slopes in the wind zone, but these are generally manageable and predictably break at or below your feet. Less predictable, is any slide that fails on weak, sugary snow near the ground, or what we call persitent slabs. Remember- persistent slabs have the potential to break deeper and wider than you might expect. Steep, rocky terrain facing the north half of the compass and particularly slopes that avalanched near the ground earlier this season should be considered suspect.

Sunny slopes will take on heat today and the danger of wet slides and sluffs increases as the day wares on. This type of avalanche dragon is easy to avoid... simply get off of and out from under steep sunny slopes during the heat of the day.

weather

Another beautiful day is on tap. Look for mostly sunny skies and temperatures climbing into the low 40's with overnight lows in the upper 20's. Winds ramp up tonight ahead of the next cold front which is expected to reach the region tomorrow afternoon. Southerly winds crank in the 40's and 50's Saturday morning and clouds stream into the area, ushering in scattered snow showers. Not looking at a lot of snow out of this storm, but a more significant weather system is expected Monday. Stay tuned... we'll have more details on strength and timing tomorrow.
