    In many areas this new snow will sit on a crust. Initial bonding will be poor. Steep gullies will be especially problematic.

  • Storm Slabs

    These new storm slabs will combine with the existing windslabs and create a wide spread avalanche problem. Watch for localized wind loading patterns and assess wind loaded areas carefully.

  • Deep Persistent Slabs

    There is a chance this deep layer could wake up with the very rapid loading pattern expected tomorrow.

Confidence

Fair - Intensity of incoming weather systems is uncertain

Weather Forecast

Snow, heavy at times for tomorrow. Forecasts vary, but we can hopefully expect anywhere from 25-35cm's. The really good news is that freezing levels will drop before the storm arrive. Valley bottom tonight, and 1800m tomorrow. The winds will be enough to form storm slabs. Mostly light winds are expected, but gusts will reach into the moderate range. The direction will be variable pre-storm, but settle down to an easterly flow by late afternoon. Alpine temps will hopefully reach -3.

Nothing new today

Snowpack Summary

Up to 2200m the snowpack has recovered from the extended thaw last week. Crusts are prevalent all the way up to the alpine right now. The alpine region reportedly has some good skiing in sheltered north aspects. Windslabs are present in specific areas 2400m and above.
