Heavy precipitation, rising freezing levels, and large, fragile cornices are keeping hazard elevated.
Travel in avalanche terrain is not recommended.
A weak layer of buried surface hoar and facets is worst at treeline in areas sheltered from previous strong south and west wind. Forecasted precipitation will be testing this layer.
Heavy precipitation, rising freezing levels and sunny breaks are combined to keep storm slabs reactive. Cornice triggers are also a concern, where strong wind and snow at upper elevations has been intense.
Freezing levels are forecasted to soar on Tuesday. Sunny breaks are possible, making natural wet loose avalanche activity likely in steep terrain features.
Numerous wet loose avalanches were reported up to size two in the Duffy Lake area.
On Monday, two explosives controlled size 3 avalanches were reported that may have released down to an early November weak layer.
Storm snow above 1900 m is being redistributed by strong to extreme winds developing reactive storm slabs in lee features. Rain saturated surface snow is present below 1800 m.
The mid pack is settling rapidly and increases in resistance.
The lower snowpack is well consolidated snow and two melt-freeze crusts from early season.
An report of large explosive controlled avalanches may have release on one of these layers.
