AVALANCHE DANGER The addition of new snow over the past 48 hours has increased the avalanche danger. The main avalanche concern will be freshly formed wind slabs along the ridge tops. These freshly formed wind slabs will be very sensitive and will easily fail under the weight of a skier. Deep buried facets still remain in the snowpack making conditions variable and unpredictable. For today, CONSIDERABLE avalanche danger exists on wind loaded slopes and a MODERATE avalanche danger exists on other slopes |
