Southerly winds began increasing yesterday ahead of a major winter storm that will impact the area through Monday. Currently, many mountains stations have 15 to 25 mph averages, with gusts in the 50’s. Across the highest peaks, average wind speeds are 35 to 50 mph, with “knock you off your feet” gusts to 70 mph. Temperatures have cooled into the low 20’s at 10,000’, and near freezing at 8,000’.

There are still concerns about isolated places where weak facets near the ground and mid pack weaknesses could be overloaded, resulting in deep slides. Activity the past week shows shallow snowpack areas exist at a variety of aspects and elevations, not just the upper elevation northerly facing slopes. As the day progresses, increasing winds will drift additional snow (weight) onto these slopes, and increase the potential for them to be triggered by backcountry users.
Bottom Line for the
There will be a rising avalanche danger today and through out the weekend. For today, there are pockets of CONSIDERABLE avalanche danger on steep, wind drifted slopes, especially those with a shallow, weak underlying snowpack. Other slopes steeper than about 35 degrees have a MODERATE danger. Wind drifts will become deeper and more widespread as the day goes on, and natural avalanche are possible. There are isolated where a deeper, larger avalanche could be triggered, especially in thinner snowpack areas.
