Don't let sunny skies lure you onto large, steep slopes.
Large slab avalanches remain possible to trigger at treeline and above.
Persistent slabs remain possible to human trigger at treeline and above, especially in areas without a supportive crust above the weak layer.
35 to 50 cm of recent snow and strong southwest winds have formed storm slabs that will be most reactive in wind-affected terrain.
Expect natural wet loose avalanches to occur when the sun warms the dry snow for the first time.
On Friday, a skier triggered size 1.5 persistent slab was reported west of Invermere on a northeast aspect at 2000 m. The crown was 25 to 60 cm deep.
35 to 50 cm of recent snow and strong southwest winds have formed storm slabs that will be most reactive in wind-affected terrain.
Below the recent snow is a 1 to 10 cm thick crust on all aspects. The thickness of the crust depends on elevation.
At upper elevations, where the crust is thinner or not present, it may still be possible to trigger persistent slabs on multiple buried weak layers of surface hoar and/or crusts in the top 120 cm of the snowpack.
In shallow snowpack areas, depth hoar (large facets) can be found near the bottom of the snowpack.
