Travel in avalanche terrain is not recommended. New snow and strong winds are driving the avalanche danger.
Deep instabilities are still present and have produced recent large avalanches.
Expect with the increasing snowfall and snow load, that this problem will continue. Natural avalanche activity may taper post storm but human triggering is possible.
Watch for newly formed and reactive storm slabs within the new snow. Potential remains for slabs to step down to deeper persistent weak layers.
No new avalanches were reported. Observations seemed limited due to thick clouds at upper elevations.
Natural avalanche activity is expected on Thursday during the storm and avalanche terrain should be avoided.
Another 20 to 35 cm of snow is forecast by Thursday afternoon. Strong southwest wind has created widespread wind effect, with deeper deposits of snow on leeward slopes. At lower elevations, the new snow may have a poor bond to the crust found up to 1300 m.
Down 50 to 100 cm a layer of surface hoar, facets, or a thin crust exists.
A persistent weak layer of surface hoar and facets overlying a crust is buried 120 to 200 cm deep.
