Avalanche Forecast

Poor - Due to the number of field observations

Overnight and Thursday: Pacific moisture is forecast to collide with the remnants of the cold air over the interior bringing 10-20 cms of dry snow. Freezing level should remain at valley bottoms and winds should be moderate from the Southwest.Friday: Continued light to moderate precipitation bringing another 5-15 cms of dry snow.Saturday: Heavy snowfall combined with strong Southwest winds and freezing levels rising to 1500 metres.

No new avalanches reported.

A new storm is forecast to add moderate new snow amounts above the dry cold surface snow that recently buried the very cold and facetted snow that was on the surface during the arctic outbreak. There is a great deal of variation in the snowpack with respect to elevation and exposure to winds. Shallow snowpack areas may be weak and facetted, and may not support the additional load of storm snow. The old storm snow (~30-50cm) overlies the late-November interface which typically consists of sun crusts on steep south facing slopes and surface hoar in sheltered areas. These weak layers are expected to be persistent, although in many areas the upper slab is not yet stiff enough for slab avalanches. When temperatures rise, and we get additional snow, expect this interface to become more reactive.
