New snow may not bond well to the old. Test before committing to larger terrain.
Concern remains for a weak layer near the base of the snowpack in shallow areas with facets over a crust.
Snowfall amounts are uncertain and may change dramatically over a short distance. If you find more than 10 cm of new snow, watch out for storm slabs.
Avalanches on weak faceted snow at the base of the snowpack are becoming less likely, but remain possible on steep, smooth slopes. This problem seems to be local to Invermere, but information is limited.
No new slab avalanches have been reported. Small wet loose avalanches were triggered by riders on Thursday.
Treeline snow depths are generally 50 to 70 cm, with deeper wind-loaded pockets in the alpine.
New snow is expected to land on a variety of different layers including sun crusts, surface hoar in sheltered areas, and wind-affected snow.
In the Invermere area, weak faceted snow at the base of the snowpack has caused several small but notable deep persistent slab avalanches.
Early-season hazards are present at all elevations. Stay alert and assess terrain carefully.
