Avalanche Forecast

Moderate - The weather pattern is stable

We're into a stable and benign weather pattern with cooling temperatures and isolated flurries.THURSDAY: Cloudy with sunny breaks and isolated flurries / Light southerly winds / Freezing levels at valley bottom / Alpine high temperatures near -8 Celsius.FRIDAY: A mix of sun and cloud and isolated flurries / Light variable winds / Freezing levels at valley bottom / Alpine high temperatures near -8 Celsius.SATURDAY: Cloudy with light flurries in the afternoon (local accumulations 5-10cm possible) / Light southwest winds / Freezing levels at valley bottom / Alpine high temperatures near -9 Celsius.

On Tuesday we had reports of a skier-triggered Size 2 wind slab (average thickness of 45cm) on a northwest aspect around 2200m in the Monashees. On Monday we had reports of a couple of skier-triggered Size 1.5 storm slab avalanches (20-35 cm thick) on a variety of aspects near 2100m elevation.Natural wind slab activity (to Size 2) was reported on Sunday up near 2200m on steep east and northwest aspects in this region.Wind slabs at higher elevations are sensitive to light triggers and have the potential to step down and trigger persistent slab avalanches.   

We've had modest snowfall amounts (15-30cm) over the past several days, with moderate southeasterly winds in some locations. Expect to find 35-50 cm of more recent snow bonding slowly to buried Feb 15th surface hoar and/or a crust, and blown into wind slabs at higher elevations. In some areas of the Monashees, snow pack tests are giving easy sudden planar results on southerly aspects around 2000m on the Feb 15th surface hoar layer (down 45cm) above a sun crust.The sun is starting to pack a punch and can trigger loose snow avalanches mid-day. The sun is also creating a thin crust on steep southerly aspects.Below 1500m a frozen rain crust is mostly supportive, but up to 1800m it can be breakable. Storm snow from last week is still bonding slowly to the previous snow surface from early February, which is now down 60-80 cm. The mid and lower snowpack are generally well settled and stable in deeper snowpack areas but may be faceted and weaker in shallower areas.
