Avalanche Forecast

Low - Due to the number of field observations

FRIDAY: Mostly cloudy with isolated flurries, light southwesterly winds, freezing levels around 1500m. SATURDAY: Mostly cloudy with isolated flurries, light southwesterly winds, freezing levels around 1500m. SUNDAY: 5-15cm new snow throughout the day, moderate to strong southwesterly winds, freezing levels rising to around 2400m.

On Thursday, no new avalanches were reported in this region. However, we currently have very limited observations in this region. Please submit your observations to the Mountain Information Network (MIN).

Fresh wind slabs may have formed below alpine ridgetops in areas where the precipitation fell as snow on Thursday afternoon. The depth of the snowpack varies greatly with elevation. Recent reports suggest the average depth is 150+cm in the alpine, 100-150cm at treeline, and decreasing rapidly below treeline where the primary hazards are rocks, stumps, and open creeks. Recent heavy rain to the mountaintops has rapidly shrunk the snowpack and has transitioned much of the snowpack from dry to moist snow. The major feature in the snowpack is a crust which was formed at the end of October and can be found approximately 100cm down at treeline elevations. However, freezing levels are forecasted to drop dramatically by Friday morning which will likely create a strong crust at most elevations and decrease the likelihood of triggering avalanches on the October crust. We currently have very limited snowpack observations within this region and it is critical to supplement this information with your own observations.
