Dry Loose
This new snow falling is forecast to be cold and dry. I think it may not bond well initially and there will certainly be a risk of loose dry avalanches running easily on the old dense snow (20221228) in steep terrain. This will become a bigger issue as the snow continues to accumulate.
Storm Slab
There will likely be a risk of storm slab on all aspects and elevations, with most risk on the mid and higher elevation E and SE slopes due to forecast W and NW winds during the storm.
Wind Slab
There will likely be a risk of storm slab on all aspects and elevations, with most risk on the mid and higher elevation E and SE slopes due to forecast W and NW winds during the storm.
