Avalanche Summary

Poor visibility and limited observations today. Suspect some loose wet activity associated with warm temperatures and rain at lower elevations (below 2200m).

Snowpack Summary

Fresh snow at upper elevations (above 2500m) sits on a variety of surfaces including temperature crusts (solar aspects) and dry snow (north aspects). Below 2500m surface crusts becoming moist and breaking down with rain and above freezing temperatures.

The mid-pack Feb 3 persistent layer is lingering and is expected to become active as day time temperatures rise on Wednesday.

Weather Summary

Tuesday: Unsettled weather with rain or snow showers (depending on elevation). Freezing levels will be in the 2300m range

Wednesday: An upper ridge starts to build resulting in clearing skies, lots of sunshine and rising freezing levels (25-2700m)

Thursday: Warm and sunny. Freezing levels rising to 3000m.
