Avalanche Summary
Two large (size 2) storm slabs were triggered with explosives near Kamloops on Thursday.
No other avalanches have been reported in the past 3 days.
Snowpack Summary
By Monday morning 10 to 20 cm of snow could have accumulated with strong southwest winds, forming deeper deposits on north and east facing slopes. This new snow will fall over a widespread melt-freeze crust, in sheltered features small surface hoar crystals  may be on it. 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/facet layer from mid February.
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
- Avoid freshly wind-loaded terrain features.
- Use ridges or ribs to avoid areas of wind-loaded snow.
- 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.
Problems
Wind Slabs
The new snow may not bond well to the underlying surface, making new slabs reactive.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.

Persistent Slabs
Triggering the mid February layer is most likely on high north facing terrain.
