Lo esencial

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 slab at the mid and upper elevations. 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 at the lower elevations 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 in depth 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

A strong cold front will blast through the region overnight and bring a period of heavy snow shower activity. New snow accumulations of 3 to 7 inches are possible by daybreak. Temperatures will be much cooler behind the front. On Monday skies will be cloudy. Snow showers are likely and are anticipated to bring another three inches of new snow to the region during the day. The strong winds will back towards the west and continue at speeds of 25 to 35 with gusts to 45 miles per hour. Temperatures will be in the single digits and teens.The strong winds and new snow will increase the hazard as newly formed wind slabs gain depth and volume. These slabs are likely to be easily triggered by humans, especially in steep avalanche prone terrain at the upper elevations. Slabs are expected to 6 to 18 inches deep. The general avalanche hazard could rise to CONSIDERABLE at the upper elevations and is expected to be MODERATE at the mid elevations and be LOW at the lower elevations.
