Wind slabs may be lingering in alpine terrain and along ridgetops. Fresh slabs could form this week if the wind picks up.
Be careful in steep alpine terrain where wind slab avalanches could be triggered.

A few natural wind slab avalanches have been reported on north and east aspects since the weekend. Most of them have been small (size 1), although the AvCan field team did see one larger (size 2) wind slab that likely occurred on Monday (photos here).
30 to 40 cm of low density snow can still be found in wind sheltered terrain, while exposed alpine terrain has likely been impacted by strong southerly winds. Recent snow is well bonded to underlying layers, with the possible exception of steep wind-loaded slopes. Snow depths at White Pass are around 100 cm in sheltered areas and closer to 200 cm on wind-loaded slopes.
