Avalanche Forecast

No new avalanches have been reported, but observations have been limited in this region. We expect widespread natural and human-triggered avalanches will be likely with the arrival of Wednesday's storm.

If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).

Over a meter of snow has fallen in high elevation alpine areas through a series of storms since last Saturday. Most of this precipitation fell as rain at treeline and below. By the end of Wednesday, another 30 to 40 cm of snow is expected, with heavy rain below 1000 m.

In the alpine, strong winds are expected to form deeper storm slabs on lee northeast through northwest-facing slopes.

Expect a rain-saturated snowpack or lack of snow at lower elevations
