Avalanche Forecast

Moderate - Due to the number of field observations

Monday: Mainly cloudy with isolated flurries (up to 5 cm possible) / Light to moderate north westerly winds / Freezing level at 1200mTuesday: Isolated flurries (5cm possible) / Light to moderate south westerly winds / Freezing level 1000m. Wednesday: 5-10cm of snow / Moderate gusting strong west winds / Freezing level at 1600m

On Sunday, ski cutting produced several size 1 to 1.5 soft slabs on immediate down wind (lee) features. Expect wind slabs to remain reactive to human triggers as winds continue to be moderate to strong with small amounts of new snow available for transport.  On Saturday we received reports of a skier triggered size 1.5 avalanche near Whistler on a north west aspect around 2100m.

Over the past two days 7-12 cm of new snow has fallen. Temperatures were steady near +1 at tree line on Sunday afternoon. Winds, however, have been consistently strong from the south, creating fresh wind slabs in exposed downwind (lee) terrain. At lower treeline and below, generally light amounts of snow or rain now overlie a melt-freeze crust which formed during Monday's warm storm from a week ago.The new snow adds to the 170cm of snow that fell during the last few weeks of January. These series of storms were accompanied by strong to extreme winds which resulted in extensive scouring and impressive cornice growth in upper elevation terrain. These accumulations sit on a crust from mid-January which generally shows signs of bonding to the overlying snow; however, it has the potential to "wake-up" with a large trigger such as a cornice fall.Below this, the snowpack is thought to be generally strong and well-settled.
