Numerous natural and skier triggered storm slab avalanches up to size 2.5 were reported on Saturday. The storm slabs were most reactive were they were sitting on a sun crust or a weak layer of surface hoar.

Riders may get surprised by widely propagating storm slabs that are sitting on a weak layer of surface hoar.

20-40 cm of recent snow and moderate southwest winds formed fresh storm slabs that have been most reactive in wind affected terrain; especially where slabs are sitting on a weak layer of surface hoar or a sun crust.

The 20-40 cm of recent snow is sitting on a variety of surfaces including hard wind affected snow, sun crusts on southerly slopes, and surface hoar on shady or sheltered slopes. 

The late February persistent weak layer combination of crust, facets and surface hoar is down 30-40 cm. Reports suggest this layer is not a problem in most areas.

Two persistent weak layers from mid February and late January are buried 50-120cm deep. No recent avalanches have been reported on these layers.

• Potential for wide propagation exists, fresh slabs may rest on surface hoar, facets and/or crust.
• Carefully assess open slopes and convex rolls where buried surface hoar may be preserved.
• Be especially cautious as you transition into wind affected terrain.
• Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
• Continue to make conservative terrain choices while the storm snow settles and stabilizes.
