Carefully assess for firm, cohesive wind slabs in exposed terrain on all aspects.

Several explosive triggered wind slab avalanches up to size 1.5 were reported on Tuesday.

Recently formed wind slabs will likely remain reactive to human triggers.

Roughly 30 to 40 cm of recent snow and moderate variable winds have formed fresh wind slabs throughout wind-exposed terrain.

The middle of the snowpack is well-settled. Weak faceted grains exist near the base of the snowpack but have not yet created a major avalanche problem, unlike some of the neighboring regions. However, we continue to track this layer and may see a problem develop as more snow accumulates and slab formation continues above it.

The average snowpack depth is around 150 cm while up to 250 cm can be found in wind-loaded areas.

Wednesday night

Cloudy with clear periods and chance of flurries / Light to moderate northeast winds / Treeline temperatures -25 to -30 C.

Thursday

Mix of sun and cloud / Light to moderate northeast ridgetop winds / Treeline temperatures -25 to -30 C.

Friday

Sunny / Light southwest ridgetop winds / Treeline temperatures -15 to -25 C.

Saturday

Mostly sunny / Moderate southwest ridgetop winds / Treeline temperatures -10 to -20 C.

• Recent wind has varied in direction so watch for wind slabs on all aspects.
• Be especially cautious as you transition into wind affected terrain.
• Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
