In sintesi

In very steep, avalanche prone terrain at the upper elevations, skiers and riders could trigger isolated pockets of soft wind slab and loose snow sloughs. While small, these avalanches could have serious consequences in long, sustained couloirs, on hanging snow fields and in cliff areas. The snowpack is mostly stable at the mid and lower elevations, and avalanches are unlikely.

    Four to eight inches of light density snow fell overnight, and southwesterly ridgetop winds at 20 to 30 miles per hour veered to the west and decreased to 5 to 15 during this period. This scenario formed isolated pockets of soft wind slab above 9,000 feet. These slabs have formed on sun crusts, wind pack and settled powder with sporadic areas of surface hoar. In very steep terrain above 9,000 feet, backcountry travelers could trigger these slabs to depths of 6 to 12 inches.

Avalanche Discussion

Weak ridging will take over for the rest of the night and into Monday. Winds will remain light from the north through the night. West winds will return during the day with some 20 to 30 mile per hours gusts at the higher elevations during the afternoon. Temperatures will fall into the lower single digits by morning and rise into the 20's and 30's under mostly sunny skies on Monday. On Monday the general avalanche hazard is expected to be low. On the peaks and along the higher ridge crests increasing winds could begin to redistribute the recent new snow. At the upper elevations some potential may exist for loose snow sluffs and isolated pockets of soft slab up to a foot in depth to be human triggered in extreme terrain. Tomorrow's sunshine may cause shallow loose snow sluffs in sunlit cliff areas.
