Avalanche Summary
No new avalanches have been reported since Monday when a natural size 2 glide slab avalanche was reported near Kamloops on a southwest-facing slope at 1500 m.
Snowpack Summary
5 to 10 cm of snow covers a melt-freeze crust. The crust exists on all aspects, except possibly high-elevation north-facing slopes. This overlies 30 to 60 cm of snow that sits above a crust in many areas, or surface hoar/facets in wind-sheltered areas.
A weak layer, buried in late January, consists of surface hoar/facets or a crust and is found 50 to 90 cm deep. This remains a lingering concern. 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.
- Keep in mind that human triggering may persist as natural avalanches taper off.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
Problems
Persistent Slabs
This is a low-probability, high-consequence situation. Choose conservative terrain, avoiding terrain traps.
