Sunshine and warmth may feel good to us, but it doesn't help the snow. It's a good time to step aside, watch from afar, and let the mountains shed some of their winter coat. Riding will be better, or at least safer, when it cools off in a few days.

Avalanche Summary
There are few observers in the field this week but reports showed a natural avalanche cycle of storm and wind slabs up to size 2 early in the week and loose wet avalanches with afternoon warming.
Snowpack Summary
Up to 50 cm arrived in the past week. This recent snow rests on previously wind affected surfaces, sun crusts (on solar aspects) and weak, sugary facets. The prolonged period of cold temperatures in February has had an overall effect of weakening the upper and mid-snowpack, as well as the basal snowpack in thinner areas.Sunshine and warm temperatures will weaken the upper snowpack; the difficult question is how quickly this will affect deeper layers. One answer is the thinner the snowpack depth, the quicker it will happen.
