Highlights

Wind affected snow and buried weak layers make human triggered avalanches likely in many areas. These weak layers deeper in the snowpack have produced a human-triggered avalanche within the past 48 hours. Avoid wind affected slopes and any slope over a ravine or other terrain trap.

    Recently formed wind slabs may be a problem 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. Today’s cold temperatures are likely to make these slabs stubborn but when combined with a buried weak layer, you’re more likely to trigger a slope.

    Weak layers in the snowpack can be triggered by the weight of a skier or rider. This was reinforced the day before yesterday when a rider triggered a slope in the woods near Jules Bowl. 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. Recent snowfall has added stress to buried weak layers.

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

Avalanche Discussion

The snowpack has grown significantly in the past few days with some snow even falling in the valleys. The new snow is putting existing weak layers further out of reach of triggering but reports of collapsing and the layers mere presence is a reminder that no green light exists yet. Today’s a weekend day with good visibility and many slopes will be tested. Gathering at the bottom of those slopes is always a risky proposition and today is no exception. Do your homework before stepping out onto more consequential terrain. This is a big forecast zone with precious few submitted observations and lots of spatial variability. Yellow doesn’t actually mean go faster.
