Unless you have a craving for dust on crust, sheltered areas on northerly aspects will be your best option. If realized, incremental snow will increase the hazard into the weekend.
Sensitivity and consequence of this new slab may be increasing with incremental loading. These slabs are sitting on previous hard surfaces (old wind slabs, temperature and sun crusts).
Persistent slabs sit over different weak layers depending on elevation & aspect. Above 1950m a buried facet layer down 20-40cm is the primary concern. Below 1950m, a faceting crust down 40-70 is presenting a more stubborn version of a similar problem
Friday: Cloudy with scattered flurries up to 4cm. Alpine High -5 C. Ridge wind west 20-40 km/hr. Freezing level 1700m.
Saturday: Flurries up to 7cm. Alpine Low -9 C; High -7 C. Ridge wind west 20 gust to 45 km/h. Freezing level valley bottom.
Sunday: Isolated flurries with trace accumulation. Alpine Low -26 C; High -9 C. Ridge wind northeast 10 km/hr
5 to 15cm new snow past 4 days across the bulletin region accompanied by strong southwesterly winds has formed slabs in the alpine and exposed tree line. New snow burying weak temperature crust up to 1900m and solar crust on solar aspects up to 2800m. Dec Facets down 20-70cm. Basal faceting & depth hoar widespread throughout area.
No new avalanche activity observed or reported over the last 4 days.
