Avalanche Forecast

Fair - Due to the number of field observations

Friday: Cloudy with showers or flurries (trace to 5mm). The freezing level is 1800-2000 m. Ridge winds are 30 gusting to 50 km/h from the south. Saturday: Periods of rain of snow (10-20 mm). The freezing level should drop from 2100 to 1600 m. Winds ease to light from the southwest. Sunday: Probably a drier day. Freezing levels should jump up to 2000-2200 m. Winds are moderate from the south.

There was one report of an avalanche that released from a rocky sun-exposed slope near Whistler on Tuesday, but details on this slide are limited. No other avalanches have been reported.

The current snow surface is highly variable with surface hoar or facetted snow reported in sheltered areas, and pockets of wind slab or a crust (from last weeks rain) in open wind-exposed terrain. Recent cold temperatures have created a strong temperature gradient in the upper snowpack resulting in facetting of the most recent snow. Winds during the past week have been variable and have blown snow into dense wind slabs on a variety of aspects or has cross-loaded gulley features. A solid rain crust is buried 10-20 cm deep at and below treeline. Another crust that was buried in mid-November is down 40-60 cm. The snow pack depth drops significantly below treeline with essentially no snow below 1600 m.
