Sea To Sky

Avalanche hazard is greatest in wind-affected areas. Avoid steep wind-affected slopes.

• Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
• Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
• Use ridges or ribs to avoid areas of wind loaded snow.

A natural cycle from the storm was observed Tuesday and Wednesday with numerous windslab avalanches to size 1.5. Though natural avalanches have tapered off, wind slabs could still be reactive to human triggering.

There are limited reports from this region. If you head into the backcountry this weekend please submit a MIN report!

20 - 40 cm of storm snow and strong southwest winds have formed wind slabs above 1900 meters. Sheltered areas continue to hold on to unconsolidated snow that is faceting with cold temperatures.

Storm snow sits on a variety of wind-affected surfaces. Notably, a stubborn windslab on southeast aspects overlies a crust found 70 cm deep up to 2200 meters. Faceting has been observed between the windslab and the crust. Professionals are concerned about the possibility of windslabs fractureing at this deeper interface.

The snowpack sits around 70 to 120 cm at treeline to 180 cm in the alpine. Much of the below treeline vegetation band is below the threshold for avalanches.
