Avalanche Forecast
Regions: Northwest Coastal.
Pay attention to warming temperatures at all elevations as this will destabilized the upper snowpack and result in increased avalanche danger.

Weather Forecast
 Â
Wednesday night: Mostly cloudy. 5-10cm of new snow. Light winds from the south. A high of +2°C and a low of -2°C in the alpine. Freezing levels rising to 1100m
Thursday: A mix of sun and clouds. No precipitation. Light winds from the south. A high of 0°C and a low of -5°C for the alpine. Freezing levels around 1000m.Â
Friday: A mix of sun and clouds. No precipitation. Light winds from the south changing to north later in the day. A high of +5°C and a low of -2°C for the alpine. Freezing levels rising to 1000m
Saturday: Mostly sunny. No precipitation. Light to moderate north winds. A high of +3°C and a low of -8°C for the alpine.Â
Avalanche Summary
Isolated, storm slab, skier cut avalanches to size 1 were reported in the area yesterday.Â
Numerous small loose wet avalanches at lower elevations were also reported.Â
Snowpack Summary
20-40cm of Storm snow is settling into a slab with warming temperatures. Below 1200m the upper snowpack is moist in most areas. The mid-February crust is now buried 40-60cms and while we have not observed avalanches on this layer, it continues to draw suspicion.
The lower snowpack is being effectively bridged by the mid-February crust and avalanches are not expected to be triggered below this layer at this time.Â
Terrain and Travel
- Watch for changing conditions today, storm slabs may become increasingly reactive.
- A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
- Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
Avalanche Problems
Storm Slabs
Up to 30cm of new snow has settled into a cohesive slab which overlies a variety of surfaces. Reactivity could vary depending on elevation and aspect. Pay attention to overhead exposure in larger avalanche terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
Wet Slabs
Temperatures are forecast to remain warm at lower elevations for the next few days. This will weaken the upper snow. Manage your overhead accordingly at lower elevations.
Aspects: All aspects.
Elevations: Below Treeline.
Likelihood: Very Likely
Expected Size: 1 - 1.5
