Avalanche Forecast

THURSDAY NIGHT - Cloudy with clear periods and isolated flurries, up to 5 cm / southwest wind, 20-50 km/h / alpine low temperature near -6 / freezing level 900 m

FRIDAY - Mainly cloudy with scattered flurries, up to 5 cm / southwest wind, 25-50 km/h / alpine high temperature near -4 / freezing level 1100 m

SATURDAY - A mix of sun and cloud with isolated flurries / west wind, 20-40 km/h, easing in the afternoon / alpine high temperature near -6 / freezing level 900 m

SUNDAY - A mix of sun and cloud / south wind, 20-30 km/h / alpine high temperature near -3  

Strong winds, recent storm snow, and warming temperatures will likely promote fresh wind slab formation. These slabs may become easier to trigger throughout the day.

There have been very few reports of avalanches in the region, however observations are limited at this time. 

In the past week there have been a few size 2-3 avalanches reported on the early November crust in both the South Columbia and neighbouring Glacier National Park region.  

If you get out into the mountains, please consider sharing your observations on the Mountain Information Network!

Strong winds on Thursday night and Friday will likely form fresh wind slabs at upper elevations. There are a couple of crusts in the mid snowpack, from mid and early November. The most prominent of these is from early November, and it has been reported that there are weak, sugary facets above and below this crust. It is down approximately 70-100 cm, and recent observations indicate that this layer has the potential to be triggered by humans. Several reports indicate that it is likely the most reactive on south facing slopes.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Fresh wind slabs will likely form throughout the day, diligently watch for changing conditions.
• If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
