Problem Details

Recent Avalanche Activity

Recent storm snow and high winds in the forecast create our avalanche problems. Suspect persistent weak layers may be hard to detect but are also lurking at or above treeline, preserved by cold temperatures.  With the new snow load heed extra caution around run-out zones, as avalanches are likely to propagate wider and run further, beware of standing below run-out zones and look to avoid pockets of wind slab. New snow-to-old snow bonding takes time and does not account for snow that is blown around and deposited.

Recent Weather

A strong North wind is in the forecast and temperature between 10-20 F through the weekend. This will preserve weakness already in the snowpack, making them harder to detect.  Recent snowfall totals of 12-15″ from Wednesday’s storm.

 

Additional Info & Media

Be extremely cautious venturing into the backcountry right now. There is a lot of new snow and human triggered avalanches are likely until the snow has more time to settle. Even small slides can pile up deep. Stay out of gullies, depressions, and terrain traps.
