Sustained southwest winds will have an ongoing supply of snow to drift into reactive wind slabs at upper elevations.

A gradual temperature rise during the storm created warmer denser snow over colder lighter snow. In many locations, storm accumulations sit on crust layers that formed in early December. This tricky combination of slab and sliding surface may require more time to recover and gain strength, and it warrants careful evaluation and cautious routing-finding. Cornices are large and looming and could reach their breaking point.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"78sb8","text":"The snowpack around treeline is complex and warrants conservative route selection. Weak faceted snow can be found near two possible crust layers that formed in early December. This crust-facet combination may become reactive with rapid loading. Our models suggest that this persistent slab problem may be most pronounced at elevations between 1400-1800. Any steep opening in the trees should be treated as suspect right now.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"6f751","text":"Average snow depths vary drastically with elevation, with 320-400+ cm in the alpine, 120-200 cm at treeline, and a drastic drop to below the threshold for avalanches below treeline.
