Avalanche Forecast

High

Ski areas are reporting reactivity of the recent snow that sits on the early Febuary crust. Resulting in avalanches up to size 1.5.

Skiers triggered a size 2.5 slab on a S aspect at 3050 m on Mt Vaux on Thursday while boot-packing.

A size 2 and 2.5 skier-triggered deep persistent slab at 2750 m on a SE aspect in the Cirque Forepeak area occurred Tuesday.

The deeper layers can still be triggered in thin snowpack areas at high elevations.

Suncrust on steep solar aspects. Isolated wind slabs in the alpine. 10-25 cm of facetted snow over the Feb 3 crust. The crust is found in most locations except above 2500 m on N aspects, and varies in thickness from 0.5-15 cm with a thicker crust in deeper snowpack areas and at lower elevations. Persistent weak facet layers remain present in the mid and bottom of the snowpack and have recently produced avalanches on the ground in rocky thin snowpack areas at higher elevations.

A few clouds during the day on Monday, become mainly cloudy at night, making isolated flurries a possibility for most regions. Moderate to strong westerly ridgetop winds. Freezing levels near valley bottom, with the alpine high of -6C during the day.

• Avalanche hazard may have improved, but be mindful that deep instabilities are still present.
• Be especially cautious near rock outcroppings, on steep convexities and anywhere the snowpack feels thinner than average.
• Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
