In sintesi

Moderate avalanche danger will exist with human triggered avalanches possible.  Wind slabs will continue to be a problem in near treeline and above treeline terrain due to recent and continuing strong to gale force winds.  Identify where wind slabs exist and avoid steep wind loaded terrain.

    Wind slabs could continue to exist on NW-N-NE-E-SE aspects in near treeline and above treeline terrain from the SW storm winds yesterday.  Winds shifted to the NE yesterday afternoon/evening and increased in speed overnight.  New wind slabs will be possible on SE-S-SW-W-NW aspects in near treeline and above treeline terrain.  These new wind slabs will continue to build today and into Tuesday as strong to gale force NE/E winds continue. 

    Look for areas of blowing snow, cornice formation, and snow surface clues as to where wind slabs have been forming.  Avoid steep wind loaded terrain where wind slabs exist.
