Weather Forecast

Light flurries are forecast to continue overnight resulting in 2-3 cm of new snow. There is a chance of broken skies on Monday combined with light northwest winds and freezing levels at valley bottoms. On Tuesday the winds should increase to strong from the southwest, and overcast skies should drop a couple of cm of dry new snow. Moderate westerly winds and freezing levels rising slightly above valley bottoms on Wednesday with 3-5 cm of new snow. 

Avalanche Summary

There are no recent avalanche observations from this region. Due to the lack of regular observations, we cannot yet issue danger ratings for the region. If you are out in the mountains, please send us your observations and help us improve the forecast.

Snowpack Summary

Early season snowpack observations are still limited in the region but there is likely enough snow for avalanches at treeline and above. The average snowpack depth at treeline is reported to be around 60cm and 120cm or more in the alpine. Surface snow tends to be variable with low density powder in sheltered areas, and wind affected snow in exposed areas. In the north of the region at Shedin creek, the snow pillow is showing a historical low of 37 cm of snow on the ground. In the southwest at Tsai creek the snow pillow is showing historical average snow depth. Recent strong southwest winds have likely formed wind slabs in leeward features at higher elevations. A series of crusts from early November were recently reported to be buried down 20-30cm.

Problems

Wind Slabs

An icon showing Wind Slabs
Recent winds may have re-distributed surface snow into wind slabs in the alpine on lee aspects. Watch for wind affected snow at higher elevations.
Use caution in lee areas. Recent wind loading has created wind slabs.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

Aspects: North, North East, East, South East, South.

Elevations: Alpine.
