Avalanche Forecast

High

No new avalanches have been reported in this forecast area.

Nearby, on Wednesday, a small (size 1), rider-triggered, loose wet avalanche was reported in the Whistler backcountry. It occurred on a west aspect in open terrain at or below treeline.

Also around Whistler, loose dry sluffing was reported in steep, north-facing terrain.

Lingering small wind slabs may exist below alpine ridgetops. 10-15 mm surface hoar in sheltered terrain is set to be buried by the incoming snowfall.

Above 1800 m, 10 - 20 cm of faceting snow sits on a supportive crust.

Below 1800 m, recent snow amounts taper quickly and the crust increases in thickness.

Where snow still exists below treeline, it is isothermal or refrozen and travel is very challenging.

Friday Night

Partly cloudy. No new snow expected. Light west or southwest ridgetop wind. Freezing level falling to valley bottom. Treeline temperature around -7 °C.

Saturday

Mostly cloudy. 0-1 cm of snow expected. Light southwest ridgetop wind. Freezing level rising to 1500 m through the day. Treeline high around -1 °C.

Sunday

Cloudy. 1-3 cm of snow expected above 750 m. Light southwest ridgetop wind. Treeline low around -5 °C.

Monday

Mostly sunny. 2-5 cm of snow expected overnight above 750 m. Possibly 10 cm closer to Pemberton. Light northwest ridgetop wind. Treeline low around -7 °C.

• Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
• Carefully evaluate steep lines for wind slabs.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
