The main concern is wind slabs at upper elevations. Previous wind has created slabs on a variety of aspects.
Recent wind from a variety of directions has formed wind slabs in places we aren't used to seeing them. Watch for wind slabs in all wind exposed terrain.
FRIDAY: Scattered flurries, moderate to strong wind from the southwest, freezing level up to 1500 m and alpine high temperatures around -3 C.
SATURDAY: Mainly cloudy with isolated flurries, moderate to strong wind from the southwest, freezing level up to 1500 m and alpine high temperatures around -2 C.
SUNDAY: Mainly cloudy with isolated flurries, moderate wind from the southwest, freezing level up to 900 m and alpine high temperatures around -4 C.
MONDAY: Mainly cloudy, light to moderate wind from the south, freezing level up to 900 m and alpine high temperatures around -4 C.
There have been no reports of avalanche activity in the past few days.
There have also been a number of glide slabs that failed naturally as very large avalanches in the Torpy area recently. Glide cracks are seemingly unpredictable and need to be given a wide berth. There are some great photos on the PGBCSki FB page. Mild temperatures heading into this weekend could increase the sensitivity of glide slabs.
Recent snow has settled with warm temperatures and been blown around by wind from various directions, resulting in wind slabs on all aspects at and above treeline. A weak layer of surface hoar buried in late December remains a concern but seems to be gaining strength. The layer has been found across much of the North Rockies region, but has seemed to be more acute in particular areas, such as around McBride and the McGregors/Torpy. It seems to be most readily found in sheltered treeline features 50 to 150 cm below the surface.
