Avalanche Forecast

Moderate - Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

SUNDAY NIGHT: Cloudy, 5 cm new snow, moderate southwest wind, treeline temperature -5 C.

MONDAY: Mix of sun and clouds, trace of new snow, moderate southerly wind, treeline temperature -5 C.

TUESDAY: Mainly cloudy, 5 cm new snow, moderate southerly wind, treeline temperature -8 C.

WEDNESDAY: Mainly cloudy, up to 4 cm new snow, moderate to strong westerly wind, treeline temperature -9 C.

Several small wind slab avalanches were triggered by skiers and riders at treeline and in the alpine on various aspects on Saturday and Friday (see this MIN report). Slab avalanches up to size 2 were triggered by explosives in the north of the region over the last couple days. A few wind slab avalanches up to size 2 released naturally in the alpine on westerly aspects on Thursday. Recent glide snow avalanche activity was reported on Wednesday. 

15-45 cm of recent snow sits on a crust below 1000 m and surface hoar in sheltered locations at and below treeline. The layers in the mid and base of the snowpack have gained strength with high snowfall amounts in January. Deeper layers appear to have gone inactive in the southern part of the region. However, in the northern part of the region (e.g. Bear Pass, Ningunsaw) there has still been regular avalanche activity on weak snow at the bottom of the snowpack with large loads such as explosives or cornice collapses.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
• Watch your sluff: it may run faster and further than you expect.
