GENERAL AVALANCHE ADVISORY

The general avalanche hazard is CONSIDERABLE above 8,000 feet and MODERATE below that elevation. Strong northwest winds and lots of new snow have loaded leeward aspects. Over three feet on new snow has fallen at the Commissary Ridge weather station on the south end of the Salt River Range since Saturday morning. Areas of unstable snow exist and human triggered avalanches are likely in steep, wind loaded avalanche starting zones at the higher elevations and possible at the mid and lower elevations. Natural avalanche activity is possible at the upper elevations.

DESCRIPTION

Dense slab avalanches one to to four feet in depth could be human triggered or release naturally above an elevation of 8,000 feet. The deeper slabs are more likely to occur on northerly aspects, failing on a buried layer of faceted snow at the base of the snowpack. Below an elevation of 8,000 feet some potential exists for humans to trigger slab avalanches up to two feet deep.
