Weather Forecast
Tuesday should bring some sunny weather, but not particularly warm temperatures. Winds are expected to be moderate from the W to NW. Another wave of warm, windy and wet weather is expected late Wednesday.
Avalanche Summary
A more isolated natural avalanche cycle continued today. Both slab and loose avalanches were observed up to size 2.0, and seemed to be confined to the storm snow.
Snowpack Summary
Between 10 and 20cm of new snow fell in the past 24hrs depending on location. Storm snow totals are now near 50cm at treeline. Reverse wind loading yesterday and "traditional" wind loading today have formed touchy storm slabs on all aspects at alpine and treeline elevations. Wind transport at ridgetop was intense at times today and some sluffing was observed in steep alpine terrain. Two separate crusts crusts buried between 50 and 100cm in the snowpack are still causing concern for a step-down avalanche.
