Avalanche Summary

On Saturday, a size 1.5 wind slab avalanche was triggered by skier on a north facing alpine slope in the Sky Pilot area near Squamish. Expect fresh wind slabs to have formed on Sunday and be reactive to human triggers in the lee of exposed ridges.

Snowpack Summary

Sunday's cold front delivered 5-10 cm of new snow to the region. Strong southwest winds have likely formed wind slabs in the lee of exposed ridges. The new snow may bond poorly to sun crusts on steep south facing slopes. The mid and lower snowpack are well settled and stable.
