BASED ON 1800 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
2300 UTC.
..MONSOON TROUGH/ITCZ
THE MONSOON TROUGH AXIS ENTERS THE ATLANTIC THROUGH THE COAST OF
GUINEA NEAR 10N15W AND EXTENDS SOUTHWESTWARD TO 05N19W. THE ITCZ
STRETCHES FROM 05N19W TO 02N35W TO 01N51W. SCATTERED MODERATE TO

GULF OF AMERICA...
AT 1800 UTC, A 1010 MB LOW PRESSURE IS CENTERED NEAR 28N91W. A
COLD FRONT EXTENDS FROM THE LOW CENTER NEAR POZA RICA, MEXICO. A
WIDE BAND OF SHOWERS AND THUNDERSTORMS, WITH GUSTY WINDS TO GALE
FORCE, IS AHEAD OF THE FRONT. FRESH TO STRONG N WINDS AND SEAS
OF 7 TO 9 FT ARE NOTED IN THE WAKE OF THE FRONT. EAST OF THE
FRONT AND LOW, MODERATE TO LOCALLY FRESH SE WINDS AND 2 TO 4 FT
SEAS PREVAIL.
FOR THE FORECAST, THE AFOREMENTIONED COLD FRONT WILL SLOWLY PROGRESS
TO THE SOUTH AND EAST INTO EARLY NEXT WEEK. STRONG THUNDERSTORMS
WILL CONTINUE ALONG AND AHEAD OF THE FRONT, PRODUCING VERY STRONG
WINDS AND ROUGH SEAS. WIDESPREAD FRESH TO STRONG N TO NE WINDS ARE
ALSO EXPECTED IN THE WAKE OF THE FRONT THROUGH SAT, WITH THE MOST
PERSISTENT STRONG WINDS OCCURRING WEST OF 95W OFFSHORE OF MEXICO
INTO EARLY SAT. LOCALLY ROUGH SEAS MAY ACCOMPANY THESE WINDS,
ESPECIALLY NEAR TAMPICO AND VERACRUZ. WINDS WILL DIMINISH BY EARLY
SUN. FARTHER EAST, LOW PRESSURE LOOKS TO STRENGTHEN IN THE EASTERN
GULF ON SAT, PRODUCING FRESH TO STRONG WINDS SURROUNDING THE LOW
AS IT MOVES NORTHEASTWARD THROUGH THE BASIN INTO EARLY NEXT WEEK.
CARIBBEAN SEA...
A WEAK RIDGE NORTH OF THE CARIBBEAN SUPPORTS GENTLE TO MODERATE
TRADES WITH THE EXCEPTION OF MODERATE TO FRESH NE WINDS JUST S
OF CABO BEATA, DOMINICAN REPUBLIC TO ABOUT 15N. SEAS ARE 3 TO 5
FT, EXCEPT IN THE LEE OF CUBA WHERE SEAS OF 1 TO 3 FT ARE NOTED.
SHALLOW MOISTURE, EMBEDDED IN THE TRADE WINDS, IS MOVING ACROSS
THE BASIN PRODUCING ISOLATED TO SCATTERED PASSING SHOWERS.
FOR THE FORECAST, FRESH TO STRONG E TO SE WINDS WILL PULSE IN
THE GULF OF HONDURAS NIGHTLY INTO SUN, AHEAD OF A COLD FRONT
MOVING SOUTHEASTWARD THROUGH THE GULF OF AMERICA. ELSEWHERE,
STRONG NE TO E WINDS WILL PULSE OFFSHORE OF COLOMBIA AND THROUGH
THE GULF OF VENEZUELA THROUGH SAT MORNING. FRESH TO STRONG WINDS
AND ROUGH SEAS ARE THEN EXPECTED TO EXPAND ACROSS MUCH OF THE

PRESSURE STRENGTHENS NORTH OF THE AREA. FRESH TO LOCALLY STRONG
NE WINDS WILL ALSO PULSE THROUGH THE WINDWARD PASSAGE INTO EARLY
NEXT WEEK.
ATLANTIC OCEAN...
A WEAK 1015 MB LOW PRESSURE IS ANALYZED NEAR 27N68W. NO SIGNIFICANT
WEATHER IS NEAR THIS LOW. A COLD FRONT IS APPROACHING THE CANARY
ISLANDS IN THE FAR EAST ATLANTIC, FOLLOWED BY STRONG NW WINDS AND
9 TO 13 FT SEAS. THE REMAINDER OF THE ATLANTIC FORECAST REGION
IS UNDER THE INFLUENCE OF A 1033 MB HIGH PRESSURE LOCATED NEAR

TO SE WINDS FROM 20N AND 31N BETWEEN 45W AND 58W. SEAS ARE 8 TO
9 FT WITHIN THESE WINDS. THE TROPICAL ATLANTIC IS CHARACTERIZED
BY GENTLE TO MODERATE TRADES AND 4 TO 7 FT SEAS.
FOR THE FORECAST WEST OF 55W, MODERATE TO FRESH SE WINDS WILL PULSE
AND LOCALLY ROUGH SEAS ARE EXPECTED EAST OF 65W INTO SUN AS A TIGHT

TO FRESH SE WINDS ARE SLATED TO DEVELOP OFFSHORE OF FLORIDA AND
THE BAHAMAS BY SAT NIGHT AHEAD OF A COLD FRONT MOVING THROUGH THE
EASTERN GULF OF AMERICA. LOOKING AHEAD, STRONG S WINDS MAY DEVELOP
OFFSHORE OF NORTHERN FLORIDA EARLY NEXT WEEK AS THE AFOREMENTIONED
