Uintas Avalanche Advisory

Forecaster: Craig Gordon

SPECIAL ANNOUNCEMENT

Many thanks to all who attended last night’s fundraiser at The Edge. While I couldn’t personally make it due to a prior commitment, I do know Matt Potratz story of survival is truly inspiring and I want to thank him for taking time out of his busy life to help support the UAC and keep fellow riders safe.

Plowing on the Mirror Lake Highway is done for the season, maintenance on Wolf Creek Pass continues. In either case, be aware the Uinta snowpack is much weaker than you might find in neighboring mountains to the east.


BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

In the wind zone at and above treeline, pockets of Level 2 (Moderate) avalanche danger exist in steep, leeward, upper elevation terrain. Human triggered avalanches are possible, especially on slopes with recent deposits of wind drifted snow.

Out of the wind and at lower elevations the avalanche danger is generally a Level 1 (Low) danger.


CURRENT CONDITIONS

Skies are partly cloudy, temperatures are in the upper teens and low 20’s, and just an inch or two of very light density snow fell in the past 24 hours. At most locations, west and northwest winds are in the 5-15 mph range, but bumped into the 20’s and low 30’s along the high ridges early this morning. Riding and turning conditions are slightly improved, but in general our snowpack is very shallow and travel is limited to low angle meadows and rock free roads.


RECENT ACTIVITY

No new avalanche activity to report.

THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

With a spike in the winds and snow available for transport, avalanche conditions have changed, and today you’ll be able to trigger shallow soft slabs along the leeward side of upper elevation ridges. Don’t let the meager storm totals fool you. Even though only a few inches of light fluffy snow fell, the old snow surface is very weak and today’s wind drifts will be sensitive to the additional weight of a rider. Look for and avoid fresh drifts along the leeward side of ridges and also in upper elevation chutes and gullies. Triggering even a small slide will result in a body bruising ride through rocks, stumps, and downed timber barely hidden under our thin snowpack.


MOUNTAIN WEATHER

High pressure is building over the region, giving us partly cloudy skies and cool temperatures. West and northwest winds will be brisk, gusting into the 30’s and low 40’s along the high peaks. Temperatures don’t vary much from where we’re at this morning and overnight lows dip into the low teens. Increasing clouds are on tap for Thursday and then another storm system dives south of the region late in the day through Friday. Little if any snow is anticipated. Looking down the pike… there are no big weather pattern changes in store.
