Avalanche Summary
Two large (size 2) storm slabs were triggered with explosives near Kamloops on Thursday.
Snowpack Summary
5 to 10 cm of snow covers a widespread melt-freeze crust, which in sheltered spots may have small surface hoar crystals on it, found treeline and below. The crust exists on all aspects, except possibly high-elevation north-facing slopes. 30 to 60 cm further down is a crust or surface hoar/facets.
A weak layer, buried in late January, consists of surface hoar, facets, and/or a crust, is found 50 to 90 cm deep.
Below this, the mid and lower snowpack is generally settled and strong.

Terrain and Travel Advice
- Be mindful that deep instabilities are still present in the snowpack.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
- Avoid freshly wind-loaded terrain features.
