AVALANCHE DANGER MORNING AFTERNOON
GENERAL AVALANCHE ADVISORY
In steep terrain at the high elevations, dangerous soft slabs that were formed by heavy snow and wind lie upon lighter snow and crusts. Yesterday a skier triggered one of these slabs in Drew's Slide to the south of the Jackson Hole ski area. He deployed an avalanche airbag and was lucky to escape injury. Similar events could happen today. At the mid elevations similar slab hazard exists although slab depths are significantly smaller. The likelihood of triggering slab avalanches will increase with daily warming, especially if slopes are affected by periods of direct sunlight. Increasing temperatures and potential sunshine will also create for the possibility of wet avalanche activity to occur. Wet slides will be most likely at mid elevations as the new surface snow weakens and could possibly occur at low elevations after the hard snow surfaces soften.
Wind and new snow have formed slabs above 8000 feet. These slabs could be easily triggered by backcountry skiers or riders in steep avalanche terrain and could have depths to three feet above 9000 feet and from one to two feet in terrain between 8000 and 9000 feet. These slabs will become more sensitive today as they are weakened by warmer temperatures and periods of direct sunshine.
