Regions: Sea To Sky.

The weather pattern is shifting. Expect wind slabs to develop at upper elevations as the wind picks up and snow accumulates Tuesday night and Wednesday.

Confidence

Moderate - Intensity of incoming weather systems is uncertain

Weather Forecast

TUESDAY NIGHT: Flurries, accumulation up to 5 cm / light to moderate southeast wind / alpine temperature -1 C / freezing level 1500 mWEDNESDAY: Flurries, accumulation 5-10 cm / moderate southwest wind / alpine temperature -2 C / freezing level 1500 mTHURSDAY: Mainly cloudy / moderate south wind / alpine temperature -1 C / freezing level 1500 mFRIDAY: Flurries, accumulation 5-10 cm / moderate south wind / alpine temperature -1 C / freezing level 1600 m

Avalanche Summary

No new avalanche activity to report.

Snowpack Summary

5-15 cm of new snow falling Tuesday night and Wednesday is expected to be redistributed at upper elevations by southwesterly winds. This sits on a melt-freeze crust or wet snow depending on elevation, except for north aspects above 2000 m where it may be sitting on dry snow and/or weak feathery surface hoar. Below 1800 m the entire lower snowpack is either moist or wet.

Avalanche Problems

Wind Slabs

Precipitation falling as snow at uppermost elevations with predominantly southerly winds is expected to develop thin wind slabs in the lee of terrain features.
Be cautious as you transition into wind affected terrain.Use ridges or ribs to avoid pockets of wind loaded snow.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
