...GULF OF TEHUANTEPEC STORM WARNING...
STRONG TO GALE FORCE NORTHERLY WINDS BEHIND A COLD FRONT MOVING
ACROSS THE GULF OF AMERICA ARE FUNNELING TROUGH THE CHIVELA PASS,
WHICH CONTINUE TO SUPPORT GALE-FORCE N TO NE WINDS IN THE GULF
OF TEHUANTEPEC ALONG WITH SEAS TO 8 FT. NORTHERLY WINDS ARE
FORECAST TO REACH STORM-FORCE THIS MORNING WHILE SEAS WILL
RAPIDLY BUILD TO 12 FT AS STRONG HIGH PRESSURE CONTINUES TO
BUILD IN THE WAKE OF THE FRONT. STORM-FORCE WINDS WILL DIMINISH
BACK TO GALE-FORCE BY MON MORNING. PEAK SEAS DURING THE PERIOD OF
STRONGEST WINDS TODAY AND TONIGHT ARE FORECAST TO BE 25 FT.
GALE-FORCE WINDS WILL THEN PREVAIL THROUGH TUE EVENING, AND
RESUME AGAIN BY THU MORNING DUE TO A STRONG RIDGE THAT WILL
DEVELOP OVER THE GULF OF AMERICA AFTER THE PASSAGE OF A SECOND
COLD FRONT.

FOR THE FORECAST, HIGH PRESSURE NORTH OF THE REGION WILL SUPPORT
FRESH TO STRONG WINDS ACROSS THE PAPAGAYO REGION THROUGH WED
ALONG WITH ROUGH SEAS IN NW SWELL FROM A STRONG GAP WIND EVENT
IN THE TEHUANTEPEC REGION. PULSING MODERATE TO FRESH NORTHERLY
WINDS ARE ALSO EXPECTED ACROSS THE GULF OF PANAMA THROUGH THU.
THE STRONG GAP WIND EVENT IN THE GULF OF TEHUANTEPEC WILL ALSO
RESULT IN ROUGH TO VERY ROUGH SEAS ACROSS THE OFFSHORE WATERS OF
GUATEMALA AND EL SALVADOR STARTING THIS AFTERNOON AND SUBSIDING
TUE NIGHT. FRESH TO STRONG WINDS WILL RESUME THU NIGHT IN THE
GULF OF PAPAGAYO. OTHERWISE, GENTLE TO MODERATE BREEZES AND
SLIGHT TO MODERATE SEAS WILL PERSIST ELSEWHERE THROUGH THE
FORECAST PERIOD.

FOR THE FORECAST, FRESH TO STRONG WINDS WILL PREVAIL OVER THE
FAR WESTERN TROPICAL WATERS THROUGH MON ALONG WITH ROUGH SEAS
THAT ARE FORECAST TO SUBSIDE BY TUE NIGHT. OTHERWISE, A STRONG
GAP WIND EVENT IN THE GULF OF TEHUANTEPEC WILL RESULT IN ROUGH TO
VERY ROUGH SEAS TO AFFECT THE OPEN WATERS FROM 07N TO 13N
BETWEEN 95W AND 110W FROM THIS EVENING THROUGH TUE NIGHT. A NEW
NW SWELL WILL AFFECT THE WESTERN WATERS W OF 130W TUE EVENING AND
