FROM THE EQUATOR TO 30N, BETWEEN 120W AND 140W. THE FOLLOWING
INFORMATION IS BASED ON SATELLITE IMAGERY, WEATHER OBSERVATIONS,
RADAR, AND METEOROLOGICAL ANALYSIS.
BASED ON 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
0900 UTC.
..INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH
THE MONSOON TROUGH EXTENDS FROM 09N79W TO 03N105W TO 05N120W.
THE ITCZ EXTENDS FROM 05N120W TO 07N125W TO BEYOND 03N140W.

OF BAJA CALIFORNIA AND A TROUGH OVER NORTH-CENTRAL MEXICO.
RECENT SCATTEROMETER AND AN EARLIER SHIP OBSERVATION ALSO
INDICATED FRESH WINDS PERSIST OFF PUNTA EUGENIA AS WELL. EARLIER
ALTIMETER SATELLITE DATA ALSO CONFIRMED LARGE WAVE HEIGHTS OFF
BAJA CALIFORNIA. THIS IS DUE TO LONG-PERIOD NW SWELL REACHING AS
FAR SOUTH AS OFF CABO SAN LUCAS AND CLARION ISLAND. GENTLE
BREEZES AND SLIGHT TO MODERATE SEAS ARE NOTED ELSEWHERE.
FOR THE FORECAST, THE MODERATE TO FRESH NW WINDS OVER THE
CENTRAL AND SOUTHERN GULF OF CALIFORNIA WILL DIMINISH THROUGH
LATE TODAY AS THE HIGH PRESSURE WEAKENS AHEAD OF AN APPROACHING
COLD FRONT. THE LARGE NW SWELL OFF BAJA CALIFORNIA WILL SUBSIDE
THROUGH TONIGHT. THE COLD FRONT WILL MOVE INTO BAJA CALIFORNIA
NORTE AND THE NORTHERN GULF OF CALIFORNIA TONIGHT THROUGH MON,
THEN STALL AND DISSIPATE OVER BAJA CALIFORNIA SUR AND THE
SOUTHERN GULF OF CALIFORNIA TUE. LARGE NW SWELL WILL FOLLOW THE
FRONT LATE MON INTO WED OFF BAJA CALIFORNIA, MAINLY NORTH OF CABO
SAN LAZARO. FARTHER SOUTH, EXPECT STRONG TO NEAR-GALE FORCE GAP
WINDS AND ROUGH SEAS ACROSS THE GULF OF TEHUANTEPEC TUE ASSOCIATED
WITH A COLD FRONT MOVING THROUGH THE WESTERN GULF OF AMERICA.
LOOKING AHEAD, EXPECT ANOTHER PULSE OF GAP WINDS POSSIBLY TO
MINIMAL GALE FORCE ACROSS TEHUANTEPEC THU.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...

FOR THE FORECAST, FRESH NE TO E WINDS WILL PULSE ACROSS THE GULF
OF PAPAGAYO INTO MID WEEK AS A MODEST PRESSURE GRADIENT PREVAILS
BETWEEN HIGH PRESSURE IN THE NORTHERN CARIBBEAN AND LOW PRESSURE
OVER NORTHWESTERN COLOMBIA. MODERATE SEAS MAY ACCOMPANY THESE
WINDS. OTHERWISE, GENTLE TO MODERATE WINDS AND SLIGHT TO MODERATE
SEAS WILL PREVAIL ACROSS THE WATERS OFFSHORE OF CENTRAL AND
SOUTH AMERICA INTO EARLY NEXT WEEK.

FOR THE FORECAST, THE HIGH PRESSURE WILL DISSIPATE AHEAD OF A
COLD FRONT APPROACHING FROM THE WEST. THE FRONT WILL MOVE
EASTWARD ACROSS THE WATERS NORTH OF 28N THROUGH EARLY TUE, THEN
CONTINUE INTO BAJA CALIFORNIA. ANOTHER ROUND OF NW SWELL WILL
FOLLOW THE FRONT, AND BRINGING 8 TO 10 FT WAVE HEIGHTS ACROSS THE
WATERS NORTH OF 20N THROUGH THE EARLY PART OF THE WEEK, AND 8 TO
9 FT NW SWELL MIXED WITH SHORTER PERIOD NE SEAS OVER THE TRADE
