Avalanche Forecast

Moderate

Nothing new reported or observed.

Expected extreme winds and light snowfalls on Tuesday could change the surface snowpack conditions. Expect even more wind slabs to develop (or add to existing hard slabs) in the Alpine. At treeline watch for fresh surface wind slabs to develop through the day.

The rest of the snowpack has seen little change for weeks now. The concerning facets and depth hoar in the lower snowpack still exist, and while the mid-pack has enough density to carry the weight of a skier above 2100m, this is not necessarily the case at lower elevations.

Overall the snowpack condition of stiff and dense wind slabs on the surface, a reasonably dense mid-pack, all sitting on the "house of cards" of deeply buried weak layers, is still a recipe for concern. Full depth avalanches are still possible, especially where thin/shallow/rocky start zones are the potential trigger point.

Tuesday will be cloudy with temps reaching -5C and light snow developing in the afternoon. Between 5 and 15cm are forecasted, but most models agree on lower amounts. Winds will be extreme and could be blowing at 100km/h out of the SW at ridgetop.

• Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Be aware of the potential for surprisingly large avalanches due to deeply buried weak layers.
