Consistent, strong, SE winds have transported snow at mid and upper elevations since yesterday afternoon, building dangerous wind slabs on West to North aspects, 2 to 3.5 feet deep. Continued winds and heavy snowfall today will maintain or increase the avalanche hazard today.
Heavy snowfall overnight and continued snowfall today could bring storm slab depth to 30″+ inches. This is a rapid load and red flag on the snowpack. While we lack weak layers and expect bonding to be good over the long term, we expect natural avalanches to be possible and human triggering likely in the short term. Most avalanches occur within 24 -48 hours of a storm, and this storm will continue to deliver through today.
Loose Dry avalanches will also be a factor today, with plenty of available low density snow. We expect natural activity, and for human triggering to be likely. The volume of loose dry avalanches may be substantial. Be cautious of terrain traps which could compound the hazard and result in enough volume to bury a person.
Glide avalanches will continue to be problematic. This is a low frequency/high consequence hazard. There is a high level of uncertainty with the timing and prediction for glide avalanche release. . The best advice is to avoid areas with glide cracks, and areas that have previously released. Old avalanche paths have the potential to re-activate, as hang-fire and the snowpack above these paths can release. With the new snow it will be extremely difficult to identify these locations. Review the seasons observations to familiarize yourself with problem area.
