Points saillants

Skiers, riders and snowmobilers who venture into steep avalanche terrain could trigger dense surface slabs and in some areas, very destructive deep hard slabs. These slabs could be triggered during the morning hours and will become increasingly sensitive to human triggers as temperatures warm. Wets slides are possible at the lower elevations after snow surfaces soften. These conditions warrant a conservative approach to steep terrain.

    Dangerous hard slab avalanches with depths to eight feet could be human triggered in areas where weak faceted snow persist near the base of the snowpack. These killer slabs could be triggered on slopes that have been crossed multiple times.

    Dense winds slabs up to two feet in depth could be triggered by humans in steep avalanche starting zones and cliff areas. These surface slabs could trigger deep hard slabs and will become increasingly sensitive to human triggers as the day progresses.

    At the lower elevations wet slides are possible on steep snow covered slopes after snow surfaces soften. Rain would increase the likelihood for wet slides to occur.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Skies are expected to be at least partially clear overnight which should allow for snow surfaces to harder by daybreak as temperatures drop into the 20s. On Sunday we will see increasing clouds in the afternoon with snow develolping by evening with rain below an elevation of 7,500 feet. A warming trend will continue into Monday. Temperatures on Sunday will rise into the mid 30s at the summit level and into the 40s at the mid elevations. Winds will back to the southwest and increase to 30 with gusts to 45 miles per hour by evening.Humans who venture into very steep avalanche starting zones and cliff areas could trigger surface slabs up to two feet in depth. In addition some potential persist for snowmobilers and skiers to trigger dangerous deep hard slabs with depths to eight feet in areas with poor snowpack structure. The general avalanche hazard is expected to be CONSIDERABLE.
