A FRONTAL BOUNDARY IS OVER THE NW WATERS. HIGH PRESSURE
DOMINATES THE WATERS N OF 18N, ANCHORED BY A 1022 MB HIGH
CENTERED NEAR 32N123W. THE PRESSURE GRADIENT BETWEEN THE AREA OF
HIGH PRESSURE AND THE COLD FRONT OVER THE NW WATERS IS SUPPORTING
FRESH TO NEAR- GALE FORCE WINDS EAST OF THE TROUGH. THE PRESSURE
GRADIENT BETWEEN THE AREA OF HIGH PRESSURE AND LOWER PRESSURE IN
THE VICINITY OF THE ITCZ IS SUPPORTING MODERATE TO FRESH TRADE
WINDS S OF 20N AND W OF 110W. A SET OF NW SWELL HAS PROPAGATED
INTO THE NW WATERS, WITH SEAS IN THE 8-14 FT RANGE. ELSEWHERE,
