Avalanche Forecast

Moderate

There were no reports of avalanche activity on Monday.

There were reports of a few explosives triggered size 2 storm and wind slab avalanches on northerly aspects in the alpine on Saturday and Sunday.

Large surface hoar is growing on the snow surface, particularly in sheltered areas. This tops around 30 cm of recent snow that is settling well and remains soft in sheltered areas but has been heavily wind-redistributed in alpine and exposed treeline terrain.

The most recognizable of several melt-freeze crusts in the lower snowpack is 100 - 150 cm deep in the Whistler area, decomposing, and not considered a problematic avalanche layer.

Snowpack height is around 120 to 150 cm at treeline and decreases rapidly below about 1500 m.

Tuesday night

Increasing cloud. 20 to 30 km/h west or northwest ridgetop wind. Freezing level 700 m.

Wednesday

Mainly cloudy. 30 km/h west and northwest ridgetop wind. Treeline temperature -6 °C. Freezing level 700 m.

Thursday

Mostly cloudy with scattered flurries bringing less than 5 cm of new snow, increasing overnight. 20-30 km/h southwest ridgetop wind. Treeline temperature -5 °C. Freezing level 700 m.

Friday

Diminishing flurries and cloud with 5 -15 cm of new snow from the previous 24 h, mainly in the south of the region. 35 km/h west ridgetop wind. Treeline temperature -6 °C. Freezing level 800 m.

• Seek out sheltered terrain where new snow hasn't been affected by wind.
• Carefully evaluate steep lines for wind slabs.
• Wind slabs are most reactive during their formation.
