Weather Forecast
Alpine winds will pick up from the SW Friday which will transport snow onto lee aspects. Only a few cm are expected Friday at upper elevations. A larger dump of snow is scheduled for Sunday but we've all heard that before.... Temperatures should stay in the -5 to -10 range.Â
Snowpack Summary
10-15cm over the last 24 hours and soft storm slabs were noted in alpine features Thursday. The alpine snowpack ranges from 50-90 cm across the region. 20-40cm has exists over the Halloween crust and facets which has been seen to 2700m. The snowpack is highly variable and wind transport was noted at ridgetop.
Avalanche Summary
Forecasters kicked off a size 1.5, 30-40cm deep soft storm slab over facets today in a steeper alpine moraine feature. It was sluggish due to the slab being so soft, but higher in the alpine these slabs could have more cohesion. Lake louise and Sunshine village were noting similar type avalanches.
