FOR THE FORECAST, MODERATE TO FRESH WINDS WILL PREVAIL OFFSHORE BAJA
CALIFORNIA THROUGH THE END OF THE WEEK. A SET OF NW SWELL WILL
MOVE INTO THE WATERS OFF BAJA CALIFORNIA NORTE BY MIDWEEK,
SUPPORTING COMBINED SEAS AS HIGH AS 9 FT. FRESH SW TO W GAP
WINDS WILL DEVELOP ACROSS THE NORTHERN GULF OF CALIFORNIA TUE AND
WED.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,

..REMAINDER OF THE AREA
A BROAD SURFACE RIDGE EXTENDS ACROSS THE WATERS NORTH OF 20N.
THE PRESSURE GRADIENT BETWEEN THIS AREA OF HIGH PRESSURE AND
LOWER PRESSURE IN THE VICINITY OF THE ITCZ IS SUPPORTING MODERATE
TO FRESH NE TRADE WINDS NORTH OF THE ITCZ TO 20N AND WEST OF

AND A MIX OF N AND S SWELL, WILL BRING ROUGH SEAS OVER THESE
WATERS.
