Fair - Due to the number of field observations
Weather Forecast
Synopsis: The next strong front is forecast to move across the province on Sunday before a ridge of high pressure builds that looks to last for several days. Saturday: Snow starting in the evening with light accumulations, moderate southwesterly winds and freezing level at valley bottom. Sunday: Cloudy with periods of snow and light northerly winds. Monday: Mainly cloud with a few flurries and light northerly winds.
Avalanche Summary
No recent avalanche activity has been reported.
Snowpack Summary
Recent snowfall may sit above a rain crust which exists in many places up to 1900m or old, stiff wind slabs at higher elevations. 75 cm below the surface you may find a hard, thick crust that was buried in mid-December. In many places this crust is overlaid by facets and/or surface hoar. In areas where the overlying slab is thick and cohesive, large avalanches are possible at this interface. Closer to the ground a crust/facet interface that formed in November seems to be dormant for the time being.
Problems
Persistent Slabs
A buried persistent weakness, down 30-70 cm, should remain on your radar as it has the potential to produce large avalanches.
Dig down to find and test weak layers before committing to a line.>Avoid convexities or areas with a thin or variable snowpack where triggering could be more likely.>
Aspects: All aspects.
Elevations: Alpine, Treeline.

Wind Slabs
Wind slabs may be found on a variety of slopes following recent changes in wind direction.
Be cautious as you transition into wind affected terrain.>Highmark or enter your line well below ridge crests to avoid wind loaded pillows.>
Aspects: All aspects.
Elevations: Alpine, Treeline.
