Avalanche Forecast

Fair - Due to the number of field observations

Generally unsettled conditions are expected for Tuesday and Wednesday before a weak system impacts the central coast on Wednesday night or Thursday morning resulting in light snowfall for the region.Tuesday: A mix of sun and cloud, light intermittent snowfall 2-5cm, treeline temperatures around -4C, ridgetop winds 20-40km/h SWWednesday: A mix of sun and cloud, light intermittent snowfall 1-3cm, treeline temperatures around -4C, ridgetop winds 20-40km/h SW-WThursday: Snowfall 4-8cm, treeline temperatures around -6C, ridgetop winds 40-60km/h W-NW

Reports of whumpfing, settlements, and recent avalanche activity from Smithers area on Sunday.Reports from the NW Coastal region over the weekend have seen natural slab avalanches up to size 2, additionally some larger size 2.5 were triggered with explosives control. Numerous size 1-2 skier remote (up to 50 m away) slab avalanches released down 60 cm all on the old buried surfaces mentioned above in the snowpack summary. A poor bond exists with the new snow and old surfaces; however, the Inland region probably lacks the snow amounts to be as reactive as the Coastal region. I would be suspicious of wind loaded slopes at all elevations, use conservative terrain choices and make observations as you travel.

The region has received between 30-55 cm of new snow which overlies a variety of old surfaces. These buried surfaces consist of weak surface facets, surface hoar (more predominant at treeline and below treeline elevations), a scoured crust, wind press, or any combination of these. Whumpfing, cracking and reports from the field indicate a very poor bond between the new snow and these old surfaces. Strong winds and slight warming may have added cohesion to the new storm slab, and have shifted the new snow into deeper, and potentially destructive wind slabs in exposed terrain.The mid and lower snowpack are generally strong and well-settled. Basal facets and depth hoar are likely to exist in some parts of the region, but triggering has become unlikely.
