2 PM PDT MON JUL 21 2003
 
THE INITIAL MOTION ESTIMATE IS 280/14.  GUIDANCE SUGGESTS A
WEST-NORTHWESTWARD TRACK FOR THE NEXT SEVERAL DAYS AS A DEEP-LAYER
RIDGE BUILDS WESTWARD FROM WESTERN NORTH AMERICA.  THERE ARE SOME
WEAKNESSES IN THE RIDGE DEPICTED BY THE GFS...BUT THESE DO NOT
APPEAR TO HAVE MUCH EFFECT ON THE FORECAST TRACK.
 
THE CONVECTIVE PATTERN REMAINS POORLY ORGANIZED AND THE INITIAL WIND
SPEED IS KEPT AT 30 KNOTS.  ALL GUIDANCE SUGGESTS WEAKENING UNDER
STRONG VERTICAL SHEAR AND THE OFFICIAL FORECAST IS FOR DISSIPATION
IN A TWO OR THREE DAYS.
