The general avalanche hazard is MODERATE. West-southwest winds have formed new soft slabs to 
two feet in depth on leeward aspects. These surface slabs could be triggered by humans who 
venture into steep avalanche starting zones with fresh deposits of wind blown snow. A remote 
potential for large loads to trigger full depth avalanches may persist in isolated areas.
