Coquihalla, Harrison-Fraser, Manning, Skagit.
Be aware of reactive wind slabs as you transition into wind-affected terrain.
A size 2.5 natural glide slab release was reported on Thursday. This avalanche occurred at treeline on a south aspect. No other significant avalanches were reported in the past few days.
A new crust exists just below the surface on solar aspects. Ongoing southerly winds have formed wind slabs near ridge crests at treeline and above. Cornices have also been by these winds.
There are several crusts in the mid/lower snowpack. Their depth ranges from 150 to 250 cm.
A large trigger, such as a cornice fall or a smaller avalanche in motion, could trigger a very large avalanche on one of these deeply buried weak layers. A single rider is unlikely to trigger this layer unless they are in a steep, rocky, and shallow snowpack area.
Saturday Night
Cloudy with clear periods, possible trace accumulation, winds south 20 km/h, treeline temperatures -8 °C.

A mix of sun and cloud, trace accumulation, winds southwest 20 km/h gusting to 40, treeline temperatures -10 to -5 °C.
