General Avalanche Advisory
Strong southwest winds this morning will continue to form wind slabs on leeward slopes at the upper elevations. These wind slab avalanches could be triggered by humans and entrain loose snow increasing in volume. If caught, these small slides could have significant hazards, especially in cliff areas, steep chutes, and terrain traps. Evaluate terrain carefully noting areas of loading and features of concern. At the mid and lower elevations, avalanches are unlikely.
TODAY'S AVALANCHE PROBLEMS
TYPE OF PROBLEM
Slabs formed by strong winds and snowfall during the past week can be triggered in steep terrain above 9,000 feet. As the winds switch direction, from the northwest yesterday to southwest today, slopes may be cross-loaded and newly formed wind slabs could be found on a variety of aspects. These slabs could be up to 3 feet in depth. Be wary of wind drifted snow above cliffs and in couloirs. At the mid and lower elevations, small slab avalanches up to a foot in depth could be human triggered on isolated terrain features.
