Avalanche Forecast

No recent avalanches have been reported.

On Wednesday, a large (size 2) avalanche was reported on a north aspect in the alpine. It is suspected to have failed on a layer of surface hoar that has produced a few isolated but surprising avalanches over the last couple of weeks, See photo below. Field observations have been limited, if you're out in the backcountry please consider submitting your observations to the Mountain Information Network.

Up to 20 cm of recent snow covers old, firm, wind-affected or crusty surfaces. Moderate to strong southerly wind has likely formed deeper deposits of fresh, reactive wind slab on lee slopes that may not be sticking well to the old surface. In isolated areas buried surface hoar may be found 20 to 40 cm deep.

Below 1500 m, a thick melt-freeze crust is buried 50 to 100 cm deep.

The mid-pack is generally strong and bridges the weak crystals at the base of the snowpack.The average snowpack depth at treeline is around 200 cm.

Sunday Night

Cloudy, with 0 to 3 cm of snow expected. 40 km/h south ridgetop wind. Treeline temperatures around -8 °C.

Monday

Cloudy, with 0 to 2 cm of snow expected. 30 to 50 km/h south ridgetop wind. Treeline temperatures around -7 °C.

Tuesday

Cloudy, with 2 to 6 cm of snow expected. 40 to 50 km/h southeast ridgetop wind. Treeline temperatures around -5 °C.

Wednesday

Cloudy, with 1 to 6 cm of new snow expected. 35 to 45 km/h south ridgetop wind. Treeline temperatures around -6 °C

• Seek out sheltered terrain where new snow hasn't been wind-affected.
• Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
• Carefully evaluate steep lines for wind slabs.
