As the storm passes hazard is slowly decreasing. Pay close attention to new snow fall amounts, if more then 25cm overnight consider the hazard in the alpine to be high.
rider triggerable storm slabs will still be found throughout the region. Sensitivity to triggering will be greatest near ridge lines and exposed terrain in the alpine and treeline where wind is a factor.
Wednesday night: Freezing levels will fall slightly to 1800m. Winds will continue to be strong from the Southwest. 10 to 20mm of precipitation throughout the region.
Thursday: Freezing levels will fall to 1200m with some lingering flurries in the wake of the storm. winds will be moderate from the West.
Friday: A ridge of high pressure will mean clear skies and light alpine winds. Freezing level will be at or near valley bottom.
Saturday: Temperature at 1500m -10. light to moderate winds from the Northwest. some light flurries expected.
We suspect a large natural cycle took place on all aspects on Wednesday due to strong winds, freezing levels up too 2200m and moderate precipitation.
The recent storm has formed reactive storm and wind slabs in the alpine and treeline. As the freezing level falls a new crust will form likely up to 1900m.
The average snowpack depth at treeline is 250 cm. The mid-November rain crust can be found down 70 to 130 cm and exists around 1900 m and below.
