Wind slabs may remain rider triggerable on north and east aspects.
Continually assess conditions throughout the day.
Conditions will vary from aspect to aspect and from morning to afternoon.
Wind slabs may remain rider triggerable on north and east aspects.
Wet loose avalanches are possible on steep sun exposed slopes when the snow surface is wet or moist.
Over the last 3 days a few size 1 skier triggered wind slabs have been reported. These Avalanches occurred at treeline or in the alpine near ridge crests.
Several small natural cornice falls were also reported, details on these avalanches are limited.
15 to 30 cm of recent snow sits over a crust/facet layer formed earlier this month. Deeper deposits will be found on north and east aspects and the crust may be on the surface on exposed ridges due to strong southerly wind. The snow surface is expected to become moist on sun exposed slopes during the day.
A widespread crust and facet layer from late January is buried 25 to 50 cm deep.
The mid to lower snowpack is generally well settled and strong. Snowpack depth ranges from 150 to 250 cm at treeline elevations.
