SYNOPSIS FOR THE E PACIFIC WITHIN 250 NM OF CENTRAL AMERICA,
COLOMBIA, AND WITHIN 750 NM OF ECUADOR
924 AM PDT Mon Sep 23 2024

.SYNOPSIS...
A CENTRAL AMERICAN GYRE WILL GENERATE PERIODS OF EXCESSIVE
RAINFALL OVER SOUTHERN MEXICO AND CENTRAL AMERICA THIS WEEK, AS
WELL AS THE ADJACENT WESTERN CARIBBEAN AND EASTERN PACIFIC WATERS
BETWEEN 80W AND 95W. THIS SCENARIO, COMBINED WITH DAYTIME
HEATING AND OROGRAPHIC LIFTING, COULD PRODUCE DANGEROUS FLASH
FLOODING AND MUDSLIDES ACROSS THE AREA. FURTHERMORE, STRONG TO
NEAR GALE FORCE WINDS, ROUGH SEAS AND THUNDERSTORMS ARE FORECAST
TO AFFECT THE OFFSHORE WATERS BETWEEN COSTA RICA AND EL SALVADOR
THROUGH THE END OF THE WEEK.

ELSEWHERE, MODERATE TO FRESH SOUTHWEST TO WEST WINDS WILL
CONTINUE THROUGH WED MORNING, BECOMING MODERATE SPEEDS WED
AFTERNOON THROUGH THE END OF THE WEEK. INCREASING WESTERLY WIND
WAVES ARE LIKELY IN THE WAKE OF TROPICAL STORM JOHN, MOVING INTO
THE WATERS OFF OF GUATEMALA TODAY, EXPANDING FARTHER EAST TOWARD
EL SALVADOR ON TUE, AND TOWARD NICARAGUA WED.
