Don't let sunny skies lure you onto large, steep slopes.
Large slab avalanches remain possible to trigger at treeline and above.
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.
30 to 40 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 naturally triggered size 2.5 persistent slab was reported near Fernie on a north aspect below a steep headwall in the alpine.
Numerous naturally triggered size 2 storm slabs were also reported on primarily north/east aspects in the alpine.
Cornices are large and looming. Avoid traveling underneath them.
30 to 40 cm of recent snow and strong southwest winds have formed storm slabs that will be most reactive in wind-affected terrain.
The recent snow sits on 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.
The mid/lower snowpack is well settled and strong in most areas.
