GULF OF TEHUANTEPEC GALE WARNING: A STRONG HIGH PRESSURE SYSTEM
CENTERED OVER THE CENTRAL UNITED STATES CONTINUES TO SUPPORT
STRONG TO GALE-FORCE N WINDS AND ROUGH SEAS IN THE GULF OF
TEHUANTEPEC. WINDS WILL DIMINISH BELOW GALE FORCE EARLY TONIGHT.
WINDS AND SEAS WILL FURTHER DIMINISH SAT AS THE HIGH PRESSURE
NORTH OF THE AREA SHIFTS EASTWARD AND THE PRESSURE GRADIENT
LOOSENS. PLEASE REFER TO THE LATEST NHC HIGH SEAS FORECAST AT
WEBSITE HTTPS://WWW.HURRICANES.GOV/TEXT/MIAHSFEP2.SHTML FOR MORE
DETAILS.

PLEASE REFER TO THE SPECIAL FEATURES SECTION FOR DETAILS ON AN
ONGOING GALE WARNING IN THE GULF OF TEHUANTEPEC.
OUTSIDE OF THE GULF OF TEHUANTEPEC, THE MEXICAN OFFSHORE WATERS
ARE DOMINATED BY A SUBTROPICAL RIDGE LOCATED WEST OF SOUTHERN
CALIFORNIA. MODERATE NORTHERLY WINDS AND MODERATE SEAS ARE
OCCURRING FROM THE SOUTHERN GULF OF CALIFORNIA TO OFF CABO
CORRIENTES AND SOUTH OF CABO SAN LAZARO TO THE REVILLAGIGEDO
ISLANDS. ELSEWHERE, LIGHT TO GENTLE WINDS AND SLIGHT TO MODERATE
SEAS PREVAIL.
FOR THE FORECAST, HIGH PRESSURE NORTH OF THE GULF OF TEHUANTEPEC
WILL CONTINUE TO SUPPORT GALE FORCE GAP WINDS AND ROUGH SEAS THROUGH
EARLY TONIGHT. FRESH TO STRONG WINDS WILL THEN PERSIST IN THE
GULF OF TEHUANTEPEC INTO EARLY NEXT WEEK BEFORE DIMINISHING. A
SURFACE TROUGH MAY IMPACT THE WATERS NEAR THE REVILLAGIGEDO
ISLANDS THIS WEEKEND, WITH FRESH TO LOCALLY STRONG WINDS AND
ROUGH SEAS POSSIBLE THIS WEEKEND INTO MON. NO SIGNIFICANT SWELL
EVENTS ARE FORECAST THROUGH THE UPCOMING WEEKEND.

A STRONG RIDGE POSITIONED WELL NORTH OF THE AREA SUPPORTS FRESH
TO STRONG EASTERLY TRADE WINDS ACROSS THE GULF OF PAPAGAYO AND
DOWNSTREAM TO 92W. THIS WAS CONFIRMED BY SATELLITE-DERIVED WIND
DATA A FEW HOURS AGO. SEAS IN THESE WATERS ARE 6-8 FT. FARTHER
WEST, MODERATE N WINDS AND ROUGH SEAS ARE OCCURRING IN THE FAR
OFFSHORE WATERS OF GUATEMALA DUE TO THE GALE-FORCE WINDS IN THE
GULF OF TEHUANTEPEC. MEANWHILE, MODERATE SOUTHERLY WINDS AND
MODERATE SEAS ARE FOUND SOUTH OF 05N. ELSEWHERE, LIGHT TO GENTLE
WINDS AND SLIGHT TO MODERATE SEAS ARE PREVALENT.
