Banff Yoho Kootenay.
We have removed the persistent slab problem, yet the Jan 30th layer remains as surface hoar on shady aspects and sun crust on solar aspects, but in isolated areas at treeline only. We consider the layer to be dormant and unlikely to be triggered.
A relatively benign weather pattern continues over the next few days. Temps will be in the -5 to -15 range at treeline. Moderate NW alpine winds Tuesday night increasing to strong on Thursday. Mostly cloudy with sunny breaks on Wednesday, then isolated flurries and cooling temps by the end of the week.
Extensive wind effect in exposed alpine/treeline areas. The Jan 30th surface hoar/ sun crust interface exists 20-30 cm below the surface and hasn't produced avalanches recently. Surface sun crusts on solar slopes into the alpine and a thin temperature crust all aspects below 1600m. Shallow snowpack areas remain weak and faceted.
No new avalanche activity observed or reported.
