Summary
Confidence
Fair - Forecast snowfall amounts are uncertain
Weather Forecast
On Saturday we are expecting 10 to 20mm of moisture with freezing levels dropping to 1000m by Sunday morning. Sunday and Monday will see another 10 to 20mm with freezing levels around 1200m. Moderate to strong winds above 1500m will accompany this system.
Avalanche Summary
One report from yesterday of a natural wind slab avalanche, size 2, on a North East aspect, wind-loaded at 2000m. A few wet snow avalanches have been reported occurring on solar aspects. Cloudy skies may keep the surface from overnight freezing and rising temperatures may increase the likelihood of loose wet avalanches and cornice failures.
Snowpack Summary
Incoming precipitation will fall on a variety of old snow surfaces that exist throughout the region. There are numerous crusts and old wind slabs buried in the snowpack above treeline that may still be problematic. Below treeline the snowpack has had numerous warming and rain events and should be bombproof for the most part. Rain has recently been reported to ridge tops in the Coquihalla region. Solar aspects are reported to be going isothermal in some areas below 1600m
