widespread valley rain and significant mountain snow expected
Monday night and Tuesday.

strong and gusty south to southwest winds will result in areas
of blowing snow... reducing visibilities below a quarter mile at
times. Travel conditions will be extremely hazardous. Some roads
may become impassable... especially due to drifting of snow and
significant accumulation by Tuesday morning.
