Recent new snow lies upon a base of faceted old snow that is most developed on steep northerly aspects above an elevation of 9,000 feet. Human triggered slab avalanches are possible at the upper elevations and are more likely on steep, north facing slopes. In isolated areas at the mid elevations; steep, wind loaded avalanche starting zones are also suspect. Avalanches are unlikely at the lower elevations.
Slab avalanches up to two feet in depth could be triggered by humans at the upper elevations and in isolated areas up to 18 inches in depth at the mid elevations. These slabs were originally formed by southwest winds, however increasing northerly winds today are expected to drift available snow onto leeward aspects along exposed ridge lines.
Skies will be mostly clear with areas of morning valley fog. Temperatures will drop into the single digits below zero overnight and rise into the teens on Monday. Winds will be northwesterly at 10 to 20 miles per hour.Areas of unstable snow exist at the upper elevations. Slab avalanches up to two feet in depth could be human triggered in steep, wind loaded avalanche starting zones. Avalanches are unlikely at the mid and lower elevations. The general avalanche hazard is expected to be MODERATE at the upper elevations and LOW at the mid and lower elevations.
