Avalanche Canada
First significant storm of the season has arrived. Alpine terrain has reached threshold depth for avalanches in some areas. Use caution around gullies and ridgelines where windslabs are most likely. Lots of uncertainty in the current snowpack and observation are very limited.
Summary
Confidence
Avalanche Summary
No recent observations were seen due to poor visibility. If you see anything, please put it on the Mountain Information Network on avalanche.ca
Snowpack Summary
30cm of recent snow has fallen and been moved around by winds creating pockets of snow along ridgelines and gullies that is up to 50cm deep. Windslabs should be expected in the upper elevations.
Most snowpack observations are made from weather stations and observations from the valley floor at this time of year so we have low confidence in snowpack structure. We are confident though that in many areas at treeline and above, the snowpack has reached a threshold depth for avalanches to occur so keep this potential on your mind.
Weather Summary
Light snow will continue to fall over the next few days days before the cooler temperatures more out of the region.
Winds are highly variable and we expect wind transport to continue at the upper elevations.
More details can be found in the Mountain Weather Forecast.
Problems
Wind Slabs
New windslabs are forming but there is lots of uncertainty about depth of these slabs as well as distribution.
