GENERAL AVALANCHE ADVISORY

Up to four feet of snow with four inches of moisture fell between Wednesday night and Sunday morning. Strong southwest winds accompanied that snowfall. At the mid and upper elevations this precipitation has increased the potential for skiers and riders to trigger large destructive deep slab avalanches and recently formed wind slab avalanches. Avalanches are unlikely at the lower elevations except on isolated terrain features.
