Weather Forecast

A trailing warm front spinning off of an Aleutian low pressure center will bring an end to the clear skies and cool weather we have been enjoying. Current models are predicting a warming spike for Friday afternoon, with freezing levels as high as 3300m. Saturday will be cloudy with scattered flurries and freezing levels up to 2200m.

Snowpack Summary

The upper snowpack is now well settled, with a surface crust forming overnight on solar aspects and breaking down with mid-day warming. At treeline and in the alpine a crust down 30-55cm persists as a concern. Widespread below 2200m and extending into the alpine on solar aspects, this was responsible for several large avalanches last week.

Avalanche Summary

A few loose wet avalanches up to size 1.0 were observed on solar aspects below treeline today. Otherwise there has been no new activity since last weekend.
