Avalanche Summary
No new avalanches were observed on Thursday or Friday. Numerous small to large loose wet avalanches up to size 2 were observed on solar aspects on Wednesday.
Snowpack Summary
Warm air temperatures and clear skies have created surface crusts on south-facing slopes at higher elevations. Moderate wind speeds from the south may have produced new localized wind slabs on northerly lee features. Wind slabs are expected to be found in areas without surface crusts, where loose snow was available to be transported by the wind. Surface hoar up to 10 mm and near-surface faceting have been noted at and near treeline in shady locations. The snow from last week is settling and generally bonding well to the late-November rain crusts. Cornices may be weakening with the continuing warm air temperatures.
