CONSECUTIVE HOURS...AND VISIBILITIES BELOW ONE HALF MILE FOR 2
HOURS.  THE WINDS WERE STRONGER AND MORE PERSISTENT THAN ANY OF THE
WINTER STORMS FROM 2009-10...AND IT IS FORTUNATE THAT THE AREA DID
NOT HAVE MORE SNOW ON THE GROUND OR RECEIVE MORE FRESH SNOW...OR THE
CONDITIONS COULD HAVE BEEN MUCH WORSE.  THROUGH THE REST OF THE
