..INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH
THE MONSOON TROUGH AXIS EXTENDS FROM NORTHERN COLOMBIA
SOUTHWESTWARD TO 07N78W TO 08N90W TO 07N97W TO 08N106W
TO LOW PRESSURE NEAR 11N120W 1013 MB AND TO 09N130W, WHERE IT
TRANSITIONS TO THE ITCZ TO BEYOND 08N140W. SCATTERED MODERATE
TO ISOLATED STRONG CONVECTION IS SEEN WITHIN 60 NM OF THE
TROUGH BETWEEN 121W-123W. SCATTERED MODERATE CONVECTION IS
FROM 08N TO 09.5N BETWEEN 120W-123W.
..OFFSHORE WATERS WITHIN 250 NM OF MEXICO
FRESH TO STRONG NORTH TO NORTHEAST WINDS, AND SEAS OF 6 TO 8 FT,
ARE OVER AND DOWNSTREAM THE GULF OF TEHUANTEPEC AS INDICATED BY
OVERNIGHT SCATTEROMETER AND ALTIMETER SATELLITE DATA PASSES.
GENTLE TO MODERATE WINDS PREVAIL WEST OF THE BAJA CALIFORNIA
PENINSULA. LIGHT TO GENTLE WINDS ARE OVER THE REMAINDER OF THE
DISCUSSION WATERS, INCLUDING IN THE GULF OF CALIFORNIA. SEAS ARE
IN THE 6 TO 8 FT RANGE WEST OF THE BAJA CALIFORNIA PENINSULA, AND 4
TO 7 FT OVER THE REMAINDER OF THE OPEN WATERS OFF MEXICO. SEAS ARE 3
FT OR LESS IN THE GULF OF CALIFORNIA.
FOR THE FORECAST, THE FRESH TO STRONG WINDS IN THE GULF OF
TEHUANTEPEC WILL DIMINISH THROUGH FRI. A SET OF LARGE NORTHWEST
SWELL WILL ENTER THE WATERS N OF PUNTA EUGENIA TODAY. THE SWELL
WILL PROPAGATE THROUGH THE REMAINDER OF THE OFFSHORE WATERS OF
BAJA CALIFORNIA THROUGH FRI NIGHT, THEN SUBSIDE DURING THE
WEEKEND. THE NEXT GAP WIND EVENT FOR THE GULF OF TEHUANTEPEC
REGION IS EXPECTED TO BEGIN SUN NIGHT, WITH WINDS POSSIBLY
REACHING GALE-FORCE BY EARLY MON MORNING.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
GENTLE TO MODERATE NORTHEAST TO EAST WINDS ARE IN THE GULF OF
PAPAGAYO REGION AS WAS NOTED IN AN OVERNIGHT SCATTEROMETER
SATELLITE DATA PASS. LIGHT TO GENTLE WINDS PREVAIL ELSEWHERE N
OF THE MONSOON TROUGH. GENTLE TO MODERATE WINDS ARE S OF THE
MONSOON TROUGH. SEAS ARE IN THE 4 TO 6 FT RANGE OVER THE
DISCUSSION WATERS PER LATEST ALTIMETER SATELLITE DATA PASSES.
FOR THE FORECAST, THE GENTLE TO MODERATE NORTHEAST TO EAST WINDS
IN THE GULF OF PAPAGAYO REGION WILL BECOME LIGHT AND GENTLE ON
FRI AND CHANGE LITTLE THROUGH SUN. MODERATE TO FRESH NORTHEAST
WINDS ARE THEN EXPECTED IN THE GULF OF PAPAGAYO REGION STARTING

..REMAINDER OF THE AREA
CORRECTED
PLEASE SEE SPECIAL FEATURES SECTION ABOVE FOR DETAILS ON A LARGE
SET OF NW SWELL IS MOVING THROUGH THE FAR NW DISCUSSION WATERS
THAT WILL CONTINUE OVER THE NORTHERN WATERS THROUGH TONIGHT
BEFORE SUBSIDING.
A WEAKENING FRONTAL TROUGH IS ANALYZED OVER THE NW WATERS ALONG
A POSITION FROM NEAR 30N129W TO 27N140W. IT IS FOLLOWED BY A
LARGE SET OF LONG-PERIOD NW SWELL AS DISCUSSED ABOVE IN THE
SPECIAL FEATURES SECTION. HIGH PRESSURE DOMINATES THE REMAINDER
OF THE WATERS N OF ABOUT 20N, ANCHORED BY A 1025 MB HIGH CENTERED
NEAR 27N184W. LIGHT TO GENTLE WINDS ARE IN THE VICINITY OF THE
HIGH CENTER AND THAT OF THE TROUGH AS SEEN IN OVERNIGHT
SCATTEROMETER SATELLITE DATA PASSES. THE PRESSURE GRADIENT
BETWEEN THE AREA OF HIGH PRESSURE AND LOWER PRESSURE WITHIN THE
MONSOON TROUGH, AND IN THE VICINITY OF THE ITCZ IS SUPPORTING
MODERATE TO LOCALLY FRESH TRADE WINDS FROM 10N TO 20N AND WEST OF
128W, AND FROM 11N TO 20N BETWEEN 120W AND 128W. AN OVERNIGHT
SCATTEROMETER SATELLITE DATA PASS INDICATES FRESH TO STRONG TRADES
FROM 10N TO 18N WEST OF 128W. MODERATE TO FRESH SOUTHERLY WINDS
PREVAIL SOUTH OF THE MONSOON TROUGH/ITCZ. SEAS ARE IN THE 8 TO 9 FT
RANGE FROM 10N TO 20N AND W OF 110W IN A MIX OF SUBSIDING NW SWELL
AND NE WIND WAVES. AN ALTIMETER SATELLITE DATA PASS FROM 02Z
REVEALED THESE SEAS. SEAS OF 6 TO 8 FT ARE ELSEWHERE.
FOR THE FORECAST, THE AFOREMENTIONED FRONTAL TROUGH WILL
DISSIPATE TODAY. THE NW SWELL OVER THE NW WATERS WILL PROPAGATE
SOUTHEASTWARD DURING THE REST OF THE WEEK, WITH SEAS GREATER THAN
8 FT COVERING MUCH OF THE WATERS N OF 10N AND W OF 113W BY FRI
EVENING BEFORE STARTING TO SLOWLY SUBSIDE. ANOTHER SET OF NW
SWELL WILL BEGIN TO MOVE INTO THE NW WATERS ON SUN AND INTO EARLY
NEXT WEEK. THE MODERATE FRESH SOUTHERLY WINDS SOUTH OF THE
MONSOON TROUGH ARE EXPECTED TO BECOME MORE PERSISTENT AT FRESH
SPEEDS BEGINNING TONIGHT EAST OF ABOUT 115W BEFORE DIMINISHING TO
GENTLE TO MODERATE SPEEDS ON SAT.
