Windslabs are still easily found in alpine areas and in isolated areas at treeline.
Good skiing in sheltered areas but the deep persistent problem is hard to forecast. Be thinking about the consequences of a large avalanche as you travel. Forecasters still have high uncertainty in many terrain features.
Windslabs are still easily found in alpine areas and in isolated areas at treeline.
The weak basal layers have produced large avalanches of late. Be thinking about whats overhead and if it has slid this season or not.
Light snowfalls will continue overnight and temperatures will become more seasonal. Winds are forecast to be just touching into moderate tomorrow out of the SW at the peaks but overall looks like a nice day.
No new avalanches were observed today but the light was poor in the light snowfalls.
Up to 15cm of snow has trickled in over the past few days wit h the cooler temperatures. There has been some noticeable facetting and weakening of the snowpack in thinner areas also. The Dec 31st facet/surface hoar interface is being found up to 2300m down 50cm and produced moderate sheers today at treeline. Wind slabs should be expected in alpine areas especially along ridgelines and in gullied/crossloaded terrain that a skier may trigger. If these windslabs fail, there is a good chance they will step down to the weak basal facets and involve the entire snowpack. Be thinking about the consequences of a large avalanche as you travel.
