The best areas for riding may overlap with where the wind has deposited loose snow. Check for reactive pockets around ridgelines and lee features.

No new avalanches have been reported.

Cornices are big, give them space both above and below, and expect large cornices to be fragile, especially with loading or daytime warming.

Strong south winds quickly impacted fresh snow. Expect to find wind-pressed surfaces, deeper and more reactive pockets around ridgelines, and a widespread crust in wind-scoured areas and lower 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 trigger from the weight of a rider, but concern exists with very large loads like cornice falls.

Tuesday

Partly cloudy and clearing, isolated overnight flurries. West ridgetop wind 10 to 30 km/h. Treeline temperature -4 °C. Freezing level valley bottom.

Wednesday

Mix of sun and cloud. Light and variable ridgetop wind. Treeline temperature -4 °C. Freezing level valley bottom.

• 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.
