Moderate

Avalanche Summary

There are only a few eyes out in the mountains, but I haven't received recent reports of avalanches. If you do get out riding please consider reporting in the MIN,

Snowpack Summary

Upper Snowpack: Recent new snow was redistributed by the wind forming wind slabs. Below this is a layer of wind hardened or settled snow.

Lower Snowpack: cold temperatures have weakened and faceted the snowpack. A basal rain crust sits near the ground.

Total snowpack depths at treeline elevations are 40-70 cm and in the alpine 60-120 cm. Below treeline elevations remain below the threshold for avalanches.
