Avalanche Summary
Numerous loose wet avalanches up to size 2 were observed within the region on Wednesday. Widespread pin-wheeling and snowballing was observed from steep, sun-exposed terrain. One wet slab was triggered from a loose wet avalanche around treeline, which was suspected to have released on a late-November rain crust.
Snowpack Summary
Dramatic warming and clear skies have caused widespread melting of the surface snow, especially on south-facing slopes. Crusts may form overnight but they will melt quickly in the mornings. Surface hoar is growing at and near treeline in shady locations and during the nights, but it may melt with the warm temperatures. The 40-60 cm of storm snow that fell last week is rapidly settling and generally bonding well to the late-November rain crusts. At high elevations, shifting winds (first from the south, and more recently from the north) have blown snow around in exposed areas creating drifts and scoured areas.
