Assess steep slopes around ridgelines and lee features for reactive wind slabs.

No new avalanches have been reported.

Snow surfaces have been significantly affected by recent winds. Expect to find extensive wind scouring, wind-pressed surfaces, and deep deposits of wind slabs around ridgelines at all elevations.

Large, fragile cornices can be found on exposed ridgelines and should be given a wide berth.

In some areas, particularly in the Haines Summit, a weak layer of facets or surface hoar is buried 50-80 cm. This layer is unlikely to be triggered by the weight of a rider, but concern exists with very large loads, such as cornice falls.

Cloudy with 0 to 4 cm of snow. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Wednesday

Mix of sun and cloud. 20 to 40 km/h north ridgetop wind. Treeline temperature -6 °C.

Thursday

Mix of sun and cloud. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -6 °C.

• Closely monitor how the new snow is bonding to the crust.
• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
