Avalanche Forecast

Moderate - Uncertainty is due to the limited number of field observations.

MONDAY NIGHT: Clearing skies / Moderate east wind / Low of -30

TUESDAY: Sunny / Moderate east wind / High of -24

WEDNESDAY: Sunny / Light east wind / High of -27

THURSDAY: Cloudy with flurries; 3-5 cm / Moderate south wind / High of -24

No new avalanches were reported on Sunday.

Several naturally triggered storm slab avalanches up to size 1.5 were reported on Saturday. The freshly formed slabs may remain reactive for longer than is typical because they are sitting on weak facets (sugary snow).

Continued strong easterly winds are expected to form reactive wind slabs on lee features at all elevations. Freshly formed wind slabs are most likely to be found on south and westerly aspects, but older wind slabs may be found on all aspects. 

Recently formed wind slabs may remain reactive to human triggers for longer than is typical due to the weak facets (sugary snow) they are sitting on.

The base of the snowpack is composed of crusts and weak faceted grains, particularly in thin snowpack areas. These deeply buried weak layers will create large, destructive avalanches if triggered. Avoid likely trigger spots such as steep, rocky slopes, with a shallow or thin to thick snowpack.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Be aware of highly variable recent wind loading patterns.
• The best and safest riding will be on slopes that have soft snow without any slab properties.
• Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
• Keep your guard up at lower elevations. Wind slab formation has been extensive.
