GULF OF TEHUANTEPEC GALE WARNING: THE PRESSURE GRADIENT BETWEEN
HIGH PRESSURE OVER THE EASTERN SLOPES OF MEXICO AND LOWER
PRESSURE WITHIN THE EASTERN NORTH PACIFIC MONSOON TROUGH IS
SUPPORTING GALE-FORCE GAP WINDS IN THE GULF OF TEHUANTEPEC.
RECENT ASCAT SCATTEROMETER PASSES MISSED THE IMMEDIATE GULF OF
TEHUANTEPEC BUT DID SHOW FRESH TO STRONG WINDS EXTENDING WELL
AWAY FROM THE SOURCE REGION TO 13N98W. THE AREA OF HIGH
PRESSURE WILL WEAKEN BY SUNRISE, WHICH WILL LOOSEN THE PRESSURE
GRADIENT AND DIMINISH WINDS BELOW GALE-FORCE. VERY ROUGH SEAS,
PEAKING AROUND 12 OR 13 FT, WILL START TO SUBSIDE BY SUNRISE AS
THE WINDS GRADUALLY DIMINISH. PLEASE READ THE LATEST HIGH SEAS
ISSUED BY THE NATIONAL HURRICANE CENTER AT WEBSITE:
HTTPS://WWW.NHC.NOAA.GOV/TEXT/MIAHSFEP2.SHTML FOR MORE
INFORMATION.

ASIDE FROM CONDITIONS IN THE GULF OF TEHUANTEPEC, A RIDGE
EXTENDS FROM HIGH PRESSURE LOCATED N OF THE AREA TO ACROSS THE
OFFSHORE FORECAST WATERS OF BAJA CALIFORNIA. THE PRESSURE
GRADIENT BETWEEN THIS RIDGE AND A TROUGH OVER WESTERN MEXICO IS
SUPPORTING MODERATE TO FRESH WINDS OVER THE GULF OF CALIFORNIA AS
DEPICTED IN RECENT ASCAT-B AND ASCAT-C SCATTEROMETER PASSES.
LIGHT TO GENTLE WINDS AND MODERATE SEAS IN LONG PERIOD NW SWELL
ARE NOTED ACROSS THE REMAINDER OF THE MEXICAN OFFSHORE WATERS,
WITH SLIGHT TO MODERATE SEAS IN THE GULF OF CALIFORNIA.
FOR THE FORECAST, GALE-FORCE NORTHERLY GAP WINDS IN THE GULF OF
TEHUANTEPEC WILL DIMINISH BY EARLY THIS MORNING, WITH FRESH TO
STRONG WINDS CONTINUING THOUGH THE END OF THE WEEK. WINDS OVER
TEHUANTEPEC WILL DIMINISH ON SAT BEFORE STRENGTHENING AGAIN ON
SAT NIGHT, POSSIBLY REACHING GALE-FORCE AGAIN SUN NIGHT. MODERATE
TO FRESH WINDS IN THE GULF OF CALIFORNIA WILL GRADUALLY DIMINISH
THROUGH WED NIGHT. FRESH N WINDS MAY DEVELOP NEAR CABO
CORRIENTES TODAY THROUGH TONIGHT.

MODERATE TO FRESH WINDS ARE IN THE GULF OF PAPAGAYO PER RECENT
ASCAT DATA, WITH LIGHT TO GENTLE WINDS ELSEWHERE N OF 06N, EXCEPT
LOCALLY MODERATE IN THE GULF OF PANAMA. GENTLE TO LOCALLY
MODERATE SOUTHERLY WINDS PREVAIL S OF 06N. SEAS ARE MAINLY
MODERATE IN MIXED SW AND NW SWELL, WITH EXCEPTION OF SLIGHT SEAS
NEARSHORE FROM COLOMBIA NORTHWARD, WHILE SEAS ARE MODERATE TO
LOCALLY ROUGH WELL OFFSHORE GUATEMALA DUE TO AN ONGOING GAP WIND
EVENT IN THE GULF OF TEHUANTEPEC.
FOR THE FORECAST, MAINLY GENTLE WINDS WILL PREVAIL N OF THE
MONSOON TROUGH OVER THE NEXT SEVERAL DAYS, EXCEPT PULSING TO
MODERATE TO FRESH IN THE GULF OF PAPAGAYO, LOCALLY STRONG AT
TIMES. GENTLE TO MODERATE WINDS WILL PREVAIL S OF MONSOON TROUGH.
MODERATE N WINDS WILL PULSE IN THE GULF OF PANAMA. SEAS ACROSS
THE OUTER OFFSHORE WATERS OF EL SALVADOR AND GUATEMALA, GENERATED
BY A GALE-FORCE GAP WIND EVENT IN THE GULF OF TEHUANTEPEC, WILL
SUBSIDE LATER THIS MORNING. OTHERWISE, MODERATE SEAS IN MIXED SW
AND NW SWELL ARE EXPECTED OVER THE REGIONAL WATERS THROUGH THE
WEEK AND INTO THE WEEKEND.
