Kernpunkte

The general avalanche hazard is MODERATE and will be increasing as the day progresses. Strong west-southwest winds will create new soft slabs on leeward aspects. These slabs will form on slick old snow surfaces and are likely to be easily triggered in steep wind loaded avalanche starting zones. On steep northerly aspects above an elevation of 9,000 feet these slabs could step down to a weak persistent layer of faceted snow at the base of the snowpack.

    Strong west-southwest winds will begin to create pockets of new wind slab on leeward aspects. These soft slabs will form on slick old snow surfaces and will gain depth and volume as the day progresses. These surface slabs could reach depths of six to 18 inches during the afternoon and could triggered by humans on steep wind loaded aspects. If triggered on steep northerly aspects above an elevation of 9,000 feet they could step down through older snow layers to weak faceted snow near the base of the snow pack and be up to two feet deep.

    Strong winds and new snow will be rapidly loading older slabs that lie upon a weak persistent layer of faceted snow on northerly and shaded aspects above an elevation of 9,000 feet. These slabs could be human triggered to depths of two feet. Previous tracks on these slopes may not be an indication of stability.
