Avalanche Advisory
Advisory: Uintas Area Mountains Issued by Craig Gordon for Friday - March 11, 2016 - 4:05am
bottom line

Pockets of MODERATE avalanche danger exist and human triggered avalanches are possible, especially on steep, wind drifted slopes and particularly in terrain with a thin, weak snowpack. While it's becoming more the exception than the rule, any avalanche that fails on weak, sugary snow near the ground, has the potential to break deeper and wider than you might expect.

In addition, while generally LOW this morning the danger of wet avalanche activity rises to MODERATE on steep, sun exposed slopes and human triggered avalanches are possible as the day heats up. Avoidance is easy... simply get off of and out from under steep sunny slopes during the heat of the day.




current conditions

High, thin clouds filtered into the region late yesterday, but cleared out early this morning, allowing the snowpack to cool somewhat. It's balmy though, with most mid and upper elevations reporting temperatures in the upper 20's and mid 30's. Southerly winds ramped up around 9:00 last night and are blowing 30-50 mph along the high peaks. Snow surface conditions run the gamut of supportable and unsupportable crusts. I think you'll find a short-lived window of corn on low and mid elevation south aspects with shallow powder still lingering on high elevation north facing slopes. Everything in-between offers character building potential.

description

While mostly well-behaved and predictable, today you'll find a few lingering drifts on steep, leeward, upper elevation slopes. In general these are manageable, easy to detect, and easier to avoid. However, if you're getting after it and your travels take you into the wind zone, look for and avoid any fat, rounded piece of snow, especially if it feels or sounds hollow like a drum.

In addition to fresh drifts, a rogue slab breaking into weak snow near the ground isn't out of the question and our usual suspects come to mind... steep, rocky terrain with a shallow, weak snowpack. Any slide that breaks to weak snow near the ground has the potential to quickly ruin your day.

description

The sun is high in the sky and all aspects and elevations are feeling the heat. While I might welcome the suns intense rays on my skin, the snowpack feels differently. Wet avalanche activity will increase on all steep slopes as the day heats up, but fortunately there's little mystery to avoiding this avalanche dragon. Simply get off of and out from under steep sunny slopes and avoid terrain traps like road cuts and gullies, especially as the snow surface gets damp and manky.

weather

Mostly sunny skies and a warm southerly flow continues over the area today with high temperatures reaching into the mid 50's. Southwest winds increase through the afternoon, gusting into the 60's by days end. Overnight lows barely reach freezing and a weakening system brings a chance of rain and snow along with slightly cooler temperatures to the region on Saturday. Unsettled and cooler weather Sunday opens the door to a stronger storm slated to arrive Monday.
