Sea To Sky

Watch for blowing snow. New wind slabs could form throughout the day, If strong winds are observed wind slabs could be further down slope than expected.

Several skier triggered size 1 wind slab avalanches were reported on westerly aspects in the alpine near Whistler over the past few days.

A new crust exists just below the surface on solar aspects as well as on all aspects below treeline. Ongoing southerly winds have formed wind slabs near ridge crests at treeline and above. The above mentioned wind have also formed large cornices. Up to 20 cm of soft snow can still be found on sheltered northerly aspects.

A couple crusts with facets sitting above them can be found at treeline and above down 60-180 cm.

The remainder of the mid and lower snowpack is well-settled and strong.
