Problems

Storm Slabs

15 cm of storm snow fell this weekend and 20 cm additional snow is expected. This will be accompanied by strong NW winds which could create enough load to see a storm slab cycle. Use extra caution as NW winds will cross load features.

Keep an eye out for reverse loading created by an upslope storm.
Be careful with reverse loaded pockets of wind slab at ridgeline.

Aspects: North East, East, South East, South, South West.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1 - 2

Loose Dry

If the sun peaks out and winds pick up watch steep rocky terrain for dry loose avalanches

Be careful of loose dry sluffing in steep, confined or exposed terrain.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1 - 1.5
