Highlights

The avalanche danger is Moderate above 8,500 feet. Weak layers of snow buried 1-5 feet deep sit under dense slabs. The likelihood of triggering slab avalanches is relatively low. However, consequences of being involved in avalanches at these depths are severe. In the low elevations avalanches are unlikely and the danger there is Low.

    Weak layers lurk 1-5 feet below dense slabs. It has been a week since the last loading event. As a result the likelihood of triggering an avalanche has gone down significantly. Due to the potential size and depth of these avalanches, the consequences remain severe. Typical warning signs such as collapsing or shooting cracks are less likely to occur. Avalanches at these depths will require large triggers or smaller triggers finding thin spots in a slab. Steep, open and unsupported slopes will be the most likely terrain to encounter a slab that will be reactive to human triggers today.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )An approaching Alberta clipper system will bring only slight chances for isolated snow showers tonight through tomorrow afternoon. Accumulation will be minimal and may approach one inch in some areas. Winds will be out of the west and northwest at 15-20 mph. Ridgetop temperatures will see overnight lows in the teens before rising back into the mid to high twenties during the day tomorrow. The weather over the next 24 hours will do little to change the snowpack and how it reacts to potential triggers. Avalanches will require large triggers or smaller triggers finding thin spots in a slab. Steep, open and unsupported slopes will be the most likely terrain to encounter a slab that will be reactive to human triggers. Because of this the danger will remain Moderate above 8,500 feet tomorrow. Avalanches are unlikely in the lower elevations where the danger will remain Low.
