As temperatures return to normal, continue to make conservative terrain choices in wind affected terrain. Wind slabs may remain reactive to human triggers for several days.




Avalanche Summary

Dry loose sluffing was observed in terrain sheltered from recent winds. We expect wind slabs to be reactive to rider triggers in wind affected terrain.

A widespread avalanche cycle occurred on Monday. For an in depth look at conditions in the North Shore Mountains, check out this update.

Snowpack Summary

Strong northerly winds have formed wind slabs on south facing slopes at treeline and above. Slabs sit over previously wind affected snow or a crust in some areas.

In the North Shore Mountains a crust is present to mountain top, buried 10-20 cm deep from a rain event near the end of the last storm.

The mid and lower snowpack are considered well-settled and strong.

The last few storms have brought winter to the North Shore Mountains. Lower-elevation areas may have reached the threshold for avalanches. Beware of buried early-season hazards.
