Summary

Confidence

Fair - Wind speed and direction is uncertain

Weather Forecast

Cold and mostly clear skies are expected for the forecast period as a dry arctic air mass begins to dominate British Columbia. Alpine temperatures are expected to hover around -16.0 with periods of strong northerly winds.

Avalanche Summary

Avalanche control in the region produced soft slabs to size 1.5 at higher elevations which formed in response to snowfall and wind on Sunday night.

Snowpack Summary

Snow depths are highly variable throughout the region although reports suggest there is an average of about 120cm of snow at upper treeline elevations. Terrain below treeline is reported to be mostly below threshold for avalanche activity.On the surface 25-45cm of new snow now overlies a generally well settled snowpack. This new snow is likely to exist as a wind slab in exposed high elevation terrain. Rain at lower elevations has continued to saturate what little snow there is. A few crusts can be found deeper in the snowpack which may have associated facets at higher elevations. Observers are not identifying any of these as cause for concern at this time, although they might be worth exploring.

Problems

Storm Slabs

An icon showing Storm Slabs
The cooling trend should help stabilize the recently developed storm slab. Forecast northerly winds, however, may redistribute loose surface snow into new windslabs on south-facing slopes.
Stay off recent wind loaded areas until the slope has had a chance to stabilize.>Avoid travelling in areas that have been reverse loaded by winds.>

Aspects: All aspects.
