Avalanche Forecast
Regions: Glacier.
Weather Forecast
Mixed weather for Friday, with sun and cloud, isolated flurries, freezing levels rising to 1400m, and moderate west winds. Tonight and into Saturday we should see another 10cm of snow with moderate to strong SW winds. Freezing levels will remain below 1500m.
Snowpack Summary
New snow from convective flurries overlies a series of crusts on most aspects up to 1900m. Reports of strong to extreme winds in the high alpine will have formed surface wind slabs. Cold, dry snow can be found on northerly slopes while solar aspects rapidly become moist with sunshine. Huge cornices line the upper ridges.
Avalanche Summary
Numerous natural avalanches to size 2.5 were observed in the highway corridor yesterday. All were failing within the recent storm snow and had shallow deposits. Neighbours surrounding Rogers Pass are still observing large natural avalanches, often triggered by large cornices.
Confidence
Due to the number of field observations
