Avalanche Canada
Strong southerly winds have created fresh wind slabs in the alpine.
Avoid steep north-facing terrain where triggering a wind slab is more likely.

High
Avalanche Summary
There has been little avalanche activity reported in the previous few days. If you do observe an avalanche, consider posting a MIN.
Looking forward, human triggering of small, fresh wind slabs and deeper, more destructive persistent weak layers remains possible.
Snowpack Summary
Light new snow amounts are beginning to bury a widespread layer of surface hoar crystals, which sit over a crust on solar aspects and low elevations.
A layer of facets, surface hoar and/or a crust formed during the February drought, are buried 30 to 50 cm deep and give easy results in snowpack tests.
Deeper in the snowpack, a weak layer of facets and a crust from early December can be found. This layer appears to be dormant but is still worth managing in thin snowpack areas in the alpine.
Weather Summary
Monday Night
Cloudy with 0 to 5 cm of snow. 30 to 60 km/h southwest ridgetop wind. Treeline temperature -7 °C.
Tuesday
Mostly cloudy with 0 to 1 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -7 °C.
Wednesday
A mix of sun and cloud. 10 to 15 km/h southwest ridgetop wind. Treeline temperature -4 °C. Freezing level 1100 m.
Thursday
Cloudy with scattered flurries. 10 to 15 km/h south ridgetop wind. Treeline temperature -3 °C. Freezing level 900 m.

Terrain and Travel Advice
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.
- Be aware of the potential for large avalanches due to buried weak layers.
Problems
Wind Slabs
Light new snow and southerly winds are keeping wind slabs reactive. Watch for reactive pockets near ridge crests.
Aspects: North, North East, East, West, North West.
Elevations: Alpine.

Persistent Slabs
A buried persistent weak layer from February is still capable of producing large avalanches.
Aspects: All aspects.
