Wind slabs will likely remain rider triggerable on north and east aspects. Recent strong wind means that wind slabs may be found farther down slope than expected.
Continually assess conditions throughout the day.
Conditions will vary from aspect to aspect and from morning to afternoon.
Wind slabs will likely remain rider triggerable on north and east aspects. Recent strong wind means that wind slabs may be found farther down slope than expected.
Wet loose avalanches are possible on steep sun exposed slopes when the snow surface is wet or moist.
Over the past couple days natural, rider and explosive triggered avalanches were reported to size 2. Activity primarily occurred in lee, wind affected terrain features at treeline and above.
30 to 50 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 40 to 80 cm deep.
The mid and lower snowpack is well settled and strong.
