Sea To Sky

Up to 20 cm of recent snow in the alpine and strong southerly wind formed wind slabs on lee features that may remain reactive to human triggers.

On Friday, skiers remotely triggered a couple wind slabs up to size 2 on northerly aspects in the alpine near Bishop River Provincial Park.

Numerous explosive triggered wind slabs up to size 2 were also reported on primarily north and east aspects in the alpine near Whistler.

Up to 20 cm of recent snow in the alpine and strong southerly wind formed wind slabs at upper elevations.

The recent snow sits on top a crust, except for northerly aspects at upper elevations where the previous snow surface remained dry.

Recent snow amounts taper quickly with elevation.

The snowpack is generally well-settled and strong, although dormant weak layers may still exist in shallow inland areas like the Duffey and Chilcotin.

Lower elevations are melting out rapidly.

• Stay off recently wind loaded slopes until they have had a chance to stabilize.
• Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
