Kernpunkte

Winter Returns!! Snow is expected on Friday through the day followed by a few days of cold temperatures.

There will be good skiing to be had, but uncertainty lies with how well the new snow will bond to the old crust.

    Größe
    1.5–2.5

    Old windslabs from Thursday's wind event will be buried by new storm snow. As the load created by the new snow increases windslabs may be easier to trigger.

    This problem will build through the day on Friday as the snow falls. Be aware that small storm slabs may step down and trigger the buried windslab as well.
