In sintesi

New and wind-driven snow continue to add stress to the snowpack, making human-triggered avalanches likely today. Sticking to lower angled slopes below 30 degrees is your best bet to avoid triggering an avalanche. A destructive avalanche was triggered in the trees yesterday which is a reminder that weak snow layers exist in this zone.

    Fresh wind slabs may be easy to trigger today. Look for signs of wind driven snow especially in steep and exposed terrain, even below tree-line in windy drainages. Cracking and wind drifts are clear signs that these wind slabs are present. These slabs are one to two feet thick and can easily bury a person especially in the many terrain traps that exist around the area.

    Weak layers in the snowpack can be triggered by the weight of a skier or rider. This was reinforced yesterday when a rider triggered a slope in the woods near the Pinnacles. This avalanche is also a reminder that trees can serve as trigger points rather than anchors given the right conditions. The best way to avoid this problem is to ride gentler slopes below 30 degrees in steepness. An avalanche involving deeper persistent layers could be three feet thick.

    Sidehilling in trees triggered the avalanche. No one was caught or injured. This avalanche occurred yesterday, 12/26.

Avalanche Discussion

Winter has finally arrived in the valleys after a long hiatus. While the cold temperatures will ultimately help to make the recent snow less reactive, the active loading from new and wind driven snow falling today will not. New snow and wind slabs need some time to settle and bond, making today not the best day to push into steep, rocky or otherwise unforgiving terrain. You’ll find conditions on the ground vary significantly by elevation due to recent warm and wet weather so remember to dig frequently and look for weak layers in the snowpack. Firm, settled slabs and new snow can yield great turns but remember that weak, faceted layers still exist within reach of a skier or rider's weight.
