Evaluate for newly formed slabs before entering high-consequence terrain.
New storm slabs have formed on all aspects and elevations. Expect to find new wind slabs on north aspect terrain near ridge crest.
On Wednesday explosive avalanche control near Kamloops triggered numerous small to large (size 1-2) storm slab avalanches. These were primarily on southeast aspects and up to 40 cm deep. Moving forward, treat the new snow with caution, especially in areas with more than 15 cm of accumulation.
Between 15 to 40 cm of snow accumulated Thursday, combined with sustained southwest wind. Up to 80 cm of snow has accumulated since last Saturday. All this snow sits on a hard melt-freeze crust.
A couple weak layers of surface hoar and/or faceted grains associated with a crust from late January and mid February may be found 80 to 100 cm deep.
The mid and lower snowpack is well settled and strong.
