Avalanche Canada
Significant recent snowfall has built reactive storm slabs at all elevations. Stick to conservative terrain.
If you see more than 20 cm of new snow, treat avalanche danger as HIGH.

Avalanche Summary
A natural avalanche cycle was observed up to size 2 through the recent stormy period, with the most recent observations on Friday. Most were on north to east aspects at treeline and above.
Snowpack Summary
Localized convective snowfall continues to accumulate variably throughout the region. 50 to 100 cm of recent snow sits over a crust on all but high north aspects. At upper elevations recent snow has been redistributed by wind.
Below the crust, the snowpack is moist and generally well consolidated. A facet/crust layer in the mid snowpack was put to the test by the significant new snow load and it does not appear to present an avalanche problem at this time.
Below treeline areas have now received enough snow to produce avalanches. Watch for "early season" type hazards such as shallowly buried stumps, rocks and creeks.
Weather Summary
Unsettled atmospheric conditions are producing convective precipitation, with locally heavy amounts in some areas.
Saturday night
Partly cloudy with scattered flurries bringing a trace of snow. 20 to 30 km/h southeast ridgetop wind. Treeline temperature -6 °C. Freezing level 300 m.
Sunday
Cloudy with convective flurries brining 5 to 15 cm of snow to many areas with local enhancements upwards of 30 cm near Comox. 20 to 40 km/h south ridgetop wind. Treeline temperature -4 °C. Freezing level 700 m.
Monday
Localized convective flurries bringing 5-15 cm of snow overnight then clearing to mostly sunny. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -5 °C. Freezing level 500 m.
Tuesday
Sunny. 30 to 40 km/h northwest ridgetop wind. Treeline temperature -4 °C. Freezing level 800 m.

Terrain and Travel Advice
- Dial back your terrain choices if you are seeing more than 20 cm of new snow.
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Stick to simple terrain or small features with limited consequence.
- Avoid freshly wind loaded terrain features.
Problems
Storm Slabs
Storm slabs exist on all aspects but they will be most reactive where wind has loaded deep deposits into lee northwest though northeast features at upper elevations.
Aspects: All aspects.
