GENERAL AVALANCHE ADVISORY

The chance continues for a single backcountry rider or skier to trigger large and dangerous deep persistent slab avalanches at the upper elevations as well as smaller wind slab avalanches at the mid and upper elevations. As new snow and strong winds occur today, these slabs will increase in sensitivity and new shallow soft wind slabs will develop. Avalanches are unlikely at the lower elevations. Careful snowpack evaluation, cautious route finding and conservative decisions are essential for safe travel in avalanche terrain.

DESCRIPTION

Large destructive slab avalanches with depths to five feet could be triggered on east through north to west aspects. These large slabs will be hard, and are likely to have crowns high up in the slide path although initiation may occur lower on the slope. These slabs will increase in sensitivity as they are further loaded by sustained snowfall and strong winds.
