Many small to large (size 1 to 1.5) wind and storm slab avalanches were triggered by humans on Saturday. They occurred on all aspects and were generally 10 to 20 cm deep.

Persistent slab activity has tapered off in the past week, although there have been about one or two reports per week of large (size 3) explosive-triggered avalanches in alpine terrain.

Strong southwest wind and around 10 to 20 cm of recent snow has formed new slabs, with the most reactive slabs being in lee terrain features at higher elevations. The slabs may become reactive at all elevations due to relatively warm air temperature on Sunday night into Monday.

A layer of surface hoar may still be found roughly 80-120 cm deep in the Selkirks and 120-160 cm deep in the Monashees. A facet/crust layer from late November may be found near the bottom of the snowpack. These layers appear to be unreactive at the moment, but could reappear as problems in the future.

• Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
• Extra caution for areas experiencing rapidly warming temperatures for the first time.
