Rider-triggered wind slab is the main concern.
Be careful with wind-loaded features, especially near ridge crests and rollovers.
Fresh and lingering wind slab exists in open and exposed areas. Expect to find them most reactive in wind-affected areas around ridgetops and cross-loaded terrain features.
No new avalanche was reported.
On Sunday, explosive control work in alpine terrain around Big White produced several wind slabs (size 1.5) on north-to east-facing aspects with one persistent slab (size 2) that stepped down to the November crust.
In open areas at treeline and above, the new snow has been redistributed by strong southerly wind. A prominent crust, formed in mid-December, is buried 30 to 50 cm below the surface and extends up to 2200 m.
In the upper snowpack, several other crust layers may exist. In the mid-snowpack, a faceted crust from mid-November can be found.
The snowpack depth is around 100 cm, tapering with elevation below 1500 m.
