Winter's Back! However early season hazards like rocks, trees and open creeks are prevalent below 1900m. There's still alot of winter left, ride conservatively out there!
Summary
Weather Forecast
Expect mainly cloudy skies today, with minor flurries, light winds at ridge-top, and freezing levels remaining in the valley bottom. Tonight we can expect 2-5 cms and a similar day on Friday. Another storm is lined up to arrive Saturday possibly bringing 20-30 cms and rising freezing levels through the weekend.
Snowpack Summary
30-40cm of new snow covers a thick supportive crust (Nov 13) with a moist near-isothermal snowpack below. Moderate winds have transported this new snow and formed soft slabs in lee features at ridge top. Below 1900m, snow depths are less than 50cm with many early season hazards (rocks, trees & open creeks!) lurking at or just below the surface.
Avalanche Summary
Natural avalanche activity has decreased as temperatures drop yesterday. However with the clearing skies field teams observed avalanches up to size 2 from Mt Macdonald and Mt Cheops that happened Tuesday evening.
Confidence
Problems
Storm Slabs
Recent snowfall & steady mod winds over the last couple of days have formed storm slabs at alpine and treeline elevations. These sit on a crust and may be easier to trigger where the slabs have stiffened due to wind.
Use caution in lee areas. Recent wind loading have created wind slabs.Carefully evaluate terrain features by digging and testing on adjacent, safe slopes.
Aspects: All aspects.
Elevations: Alpine, Treeline.
