In sintesi

The chance persists for skiers and riders to trigger pockets of recently developed wind slab in very steep, wind-loaded terrain at the higher elevations. As the day progresses, strong winds and new snowfall will begin to build new pockets of shallow wind above 7,500 feet. These slabs are forming on firm sliding surfaces. Monitor the onset of stronger snowfall and the degree to which strong winds are transporting available snow and building new slabs. The springtime snowpack below 7,500 feet is mostly stable, and avalanches are unlikely.

    Above 9,000 feet, backcountry travelers might still be able to trigger recently developed wind slabs up to two feet deep on very steep, avalanche prone slopes. New snowfall and strong winds will increase the hazard during the day as new slabs build above 7,500 feet. These slabs will form on a variety of snow surfaces which include sun crusts, firm wind pack and settled powder. By this evening, skiers and riders could trigger these new slabs to depths of six to twelve inches in heavily wind loaded terrain.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Southwesterly flow could bring some light snowfall to the region overnight and into Sunday. A low pressure system off the coast of the Pacific Northwest will move into the region late in the day on Sunday, and moderate to heavy snowfall will be possible. Overnight lows in the mountains will be in the upper teens before rising into the low 20s during the day. Southwesterly ridgetop winds will increase to 25 to 40 miles per hour as a jet streak moves overhead.The general avalanche hazard is expected to be MODERATE on Sunday. A chance persists for backcountry travelers to trigger recently developed wind slabs up to two feet deep in very steep, wind-loaded terrain above 9,000 feet. Late in the day, strong winds and snowfall will begin to form shallow pockets of new wind slab on leeward slopes. These slabs will form upon firm sliding surfaces in terrain that is exposed to the wind or to the sun.
