Human triggered avalanches are possible at all elevations. Pockets of areas where human triggered avalanches are likely exist at upper elevations due to wind slabs that formed during and after the last storm cycle. These avalanches may occur on isolated terrain features where recent snow has loaded and they may be large enough to bury a person. Yesterday, a human triggered avalanche north of Brundage Ski Area demonstrated that the snowpack is still highly variable and sensitive to human triggers.

The Avalanche Hazard is Considerable on upper elevation, wind affected ridges and slopes.  Strong winds combined with recent snowfall have created sensitive wind slabs on both windward and leeward slopes affected by SE, SW and S winds over the last few days.  Avoid traveling on or near corniced ridgelines as newly formed cornices are very sensitive and breaking farther back than you might expect. Loose snow avalanches or sluffs are likely on terrain over 35 degrees.

A moderate avalanche hazard exists after 6-10 inches of cold, low-density snow fell above a solid melt/freeze layer. Loose dry snow avalanches that are large enough to injure a person are possible on all aspects where the terrain is greater than 35 degrees. At the upper elevations, winds have transported the new snow and formed fresh wind slabs. New snow and moderate winds throughout the day will continue to build an additional load.

The risk of triggering an avalanche is generally Low throughout the PAC advisory area today. Warm temperatures and a lack of significant snow accumulations have allowed the snowpack to strengthen over the last two weeks. High elevation ridgelines and other features may still harbor scattered windslabs that are sensitive enough to trigger especially where they are resting on firm snow or crusts below. Use normal caution while traveling and good group management.  Remember, Low Hazard does not mean No Hazard.

The Avalanche Hazard is Moderate today.  Lower elevation slopes are saturated and with a rain line near 7000 feet today, expect an increase in loose/wet avalanches.   Wind slabs are the primary concern on upper elevation, exposed slopes that have been affected by SW, W and NW winds.  Avoid traveling on steeper slopes with stiff or hollow feeling snow, watch for obvious texture changes and wind deposited snow. Cornices are starting to grow and will become less stable as temperatures warm.

The Avalanche Hazard is Moderate today. Rain on snow is possible below 6,000 feet which increases the wet avalanche hazard. Freshly formed and lingering wind slabs exist in upper elevation exposed terrain. The upper 4 inches of the snowpack is not well bonded to the crust. Travelers should avoid areas with recent evidence of wind loading, and watch for wet avalanches and saturated steep slopes.

A moderate avalanche hazard exists above 6,000 feet due to freshly formed and lingering wind slabs. New snow and ridgetop winds have created fresh slabs and older slabs remain from last week's wind event. Warm temperatures have stabilized most of the lingering slabs, but isolated areas with sensitive wind slabs still exist. Travelers should avoid steep slopes with recent evidence of wind loading. Below 6,000 feet, the avalanche hazard is low

BOTTOM LINE Moderate hazard exists today at mid and upper elevations due to a persistent weak layer above the Thanksgiving rain crust.  Isolated wind slabs can also be found near ridgetops and on upper elevation, exposed slopes. A rapid warmup Friday and Saturday, and rain to nearly 7000 feet will keep the avalanche hazard around until temperatures allow the snowpack to refreeze.  Pay attention to changing conditions and a high level of variability as you travel through the mountains today.

Moderate avalanche danger exists today at mid and upper elevations due to persistent slabs that exist above the buried Thanksgiving rain crust. A secondary problem, wind slabs, can be found near ridges and other exposed areas. While these slabs may be difficult to trigger, the shallow snowpack and numerous obstacles will increase the consequences if you are caught in an avalanche. The safest terrain (and arguably best snow quality) can be found in low angled, sheltered areas.

The primary avalanche problem today is wind slabs on exposed ridges and upper elevation slopes. Recent weather has stiffened the upper snowpack. Variability is the name of the game with significant changes found on different aspects.  Multiple weak layers exist in the upper snowpack and are just starting to become reactive as the snow adjusts to these changes.  Continue to use cautious route selection, careful snowpack evaluation, and good travel protocols.
