TROPICAL WEATHER DISCUSSION FOR NORTH AMERICA, CENTRAL AMERICA
GULF OF AMERICA, CARIBBEAN SEA, NORTHERN SECTIONS OF SOUTH
AMERICA, AND ATLANTIC OCEAN TO THE AFRICAN COAST FROM THE

IMAGERY, WEATHER OBSERVATIONS, RADAR AND METEOROLOGICAL ANALYSIS.
BASED ON 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
0940 UTC.
..SPECIAL FEATURES
GULF OF AMERICA GALE WARNING: A STRONG COLD FRONT WILL MOVE INTO THE
NORTHERN GULF SAT NIGHT AND SHIFT QUICKLY ACROSS THE BASIN THROUGH
EARLY MON. STRONG TO NEAR-GALE NORTHERLY WINDS AND ROUGH SEAS WILL
FOLLOW THE FRONT. GALE-FORCE WINDS AND VERY ROUGH SEAS ARE
EXPECTED TO DEVELOP OFFSHORE OF TAMPICO ON SUN AND NEAR THE COAST
OF VERACRUZ SUN AFTERNOON THROUGH SUN NIGHT. SEAS IN THESE AREAS
OF WINDS ARE EXPECTED TO BUILD TO 12 TO 14 FT. WINDS AND SEAS
SHOULD GRADUALLY SUBSIDE FROM NW TO SE MON THROUGH TUE IN THE WAKE
OF THE FRONT.
ATLANTIC GALE WARNING: THIS SAME STRONG COLD FRONT MOVING THROUGH
THE GULF OF AMERICA THIS WEEKEND WILL EXIT THE SE U.S. COAST LATE
SUN MORNING AND SHIFT SOUTHEASTWARD ACROSS PORTIONS OF THE W AND
CENTRAL ATLANTIC WATERS THROUGH MID WEEK. GALE FORCE NW WINDS ARE
EXPECTED BEHIND THE FRONT, N OF 29.5N BETWEEN 80W AND 73W, LATE
SUN AFTERNOON THROUGH AROUND MIDNIGHT SUN BEFORE LIFTING N OF 31N
SUN NIGHT. SEAS DURING THIS TIME WILL BUILD 12 TO 15 FT. THE FRONT
IS EXPECTED TO STALL AND WEAKEN BY WED FROM THE CENTRAL ATLANTIC
TO CENTRAL PORTIONS OF THE DOMINICAN REPUBLIC, WITH WINDS AND SEAS
DIMINISHING SIGNIFICANTLY BEHIND THE FRONT TUE THROUGH WED NIGHT.

..MONSOON TROUGH/ITCZ
THE MONSOON TROUGH EXITS AFRICA NEAR 12N16.5W AND EXTENDS
SOUTHWARD TO NEAR 08N17.5W, WHERE IT TRANSITIONS TO ITCZ, AND
CONTINUES TO 02.5N20W TO 00.5N34W TO 01.5N41W TO THE COAST OF
BRAZIL NEAR 00.5N50W. SCATTERED MODERATE ISOLATED STRONG
CONVECTION IS NOTED S OF 05.5N BETWEEN 11W AND 51W.
..GULF OF AMERICA
A GALE WARNING IS IN EFFECT SUN AND SUN NIGHT FOR THE WESTERN AND
SW GULF. PLEASE, SEE THE SPECIAL FEATURES SECTION FOR MORE
INFORMATION.
HIGH PRESSURE OVER THE WESTERN ATLANTIC EXTENDS A RIDGE WESTWARD
ALONG 27N INTO THE CENTRAL GULF REGION. THE TIGHT PRESSURE
GRADIENT BETWEEN THE AFOREMENTIONED RIDGE AND LOWER PRESSURE ALONG
A TROUGH JUST OFF THE NW COAST OF THE YUCATAN SUPPORT FRESH TO
STRONG SE WINDS AND SEAS OF 5-8 FT SOUTH OF 26N AND BETWEEN 87W
AND 91W, JUST NORTH OF THE YUCATAN PENINSULA. ELSEWHERE, MODERATE
OR WEAKER WINDS AND SLIGHT TO MODERATE SEAS PREVAIL.
THE SOUTHERLY WIND FLOW IN THE WESTERN GULF WATERS IS LIFTING
SMOKE FROM AGRICULTURAL FIRES IN SE MEXICO NORTHWARD, PRODUCING
HAZY SKIES W OF 92W. IN ADDITION, THE WARMER SOUTHERLY WIND FLOW,
MOVING ACROSS THE COOLER COASTAL WATERS IS ALSO CAUSING THE
DEVELOPMENT OF AREAS OF DENSE FOG WITH LOW VISIBILITIES, FROM THE
NE MEXICAN COAST TO SE LOUISIANA AND THE FLORIDA BIG BEND TONIGHT,
THAT IS EXPECTED TO LINGER INTO SAT MORNING. DENSE FOG ADVISORIES
ARE ALREADY IN EFFECT FOR THESE COASTAL WATERS.
FOR THE FORECAST, THE ATLANTIC RIDGE WILL MAINTAIN MODERATE TO
LOCALLY FRESH SOUTHERLY WINDS AND MODERATE SEAS ACROSS THE CENTRAL
GULF THROUGH SAT EVENING. LOCALLY STRONG E TO SE WINDS WILL PULSE
NORTH OF THE YUCATAN PENINSULA THIS AFTERNOON AND TONIGHT AS A
TROUGH DEVELOPS OVER THE REGION. A STRONG COLD FRONT WILL MOVE
INTO THE NORTHERN GULF SAT EVENING AND SHIFT QUICKLY ACROSS THE
BASIN THROUGH EARLY MON, PRODUCING FRESH TO NEAR-GALE NORTHERLY
WINDS AND ROUGH SEAS BEHIND IT. GALE-FORCE WINDS AND VERY ROUGH
SEAS ARE EXPECTED OFFSHORE OF TAMPICO SUN AND OFFSHORE OF VERACRUZ
SUN AFTERNOON AND NIGHT. WINDS AND SEAS SHOULD GRADUALLY SUBSIDE
FROM NW TO SE MON THROUGH TUE IN THE WAKE OF THE FRONT.
..CARIBBEAN SEA
AN EXPANSIVE ATLANTIC SUBTROPICAL RIDGE IS LOCATED NORTH OF THE
ISLANDS ALONG 27N, AND SUPPORTS STRONG TO NEAR GALE-FORCE
EASTERLY WINDS AND ROUGH SEAS TO 11 FT IN THE SOUTH-CENTRAL
CARIBBEAN. A PARTIAL SCATTEROMETER SATELLITE PASS CAPTURED PEAK
WINDS TO 30 KT IN THE GULF OF VENEZUELA. FRESH TO STRONG E-SE
WINDS AND SEAS OF 5-8 FT ARE FOUND IN THE GULF OF HONDURAS.
MODERATE TO FRESH EASTERLY WINDS AND MODERATE SEAS ARE OCCURRING
IN THE NORTH- CENTRAL AND EASTERN CARIBBEAN AND MUCH OF THE NW
CARIBBEAN. LIGHT TO GENTLE WINDS AND SLIGHT SEAS ARE EVIDENT IN
THE LEE OF CUBA. SHALLOW MOISTURE EMBEDDED IN THE TRADE WIND FLOW
IS NOTED ACROSS THE BASIN, AND IS YIELDING ONLY SCATTERED SHOWERS
NEAR THE COASTS OF COSTA RICA AND PANAMA.
FOR THE FORECAST, THE PRESSURE GRADIENT BETWEEN THE ATLANTIC
RIDGE AND THE COLOMBIAN LOW, WILL SUPPORT FRESH TO STRONG TRADE
WINDS IN THE EASTERN GULF OF HONDURAS THROUGH SAT NIGHT, AND
ACROSS THE SOUTH-CENTRAL CARIBBEAN THROUGH SUN, BEFORE
DIMINISHING. WINDS WILL REACH NEAR-GALE FORCE EACH NIGHT OFFSHORE
OF COLOMBIA. MODERATE TO OCCASIONALLY FRESH TRADE WINDS ARE
EXPECTED FOR THE REST OF THE CARIBBEAN THROUGH SUN NIGHT. FARTHER
EAST, ROUGH SEAS WILL LINGER E OF THE LESSER ANTILLES THROUGH SAT
NIGHT AS N SWELL PROGRESSES ACROSS THE CENTRAL TROPICAL ATLANTIC.
A STRONG COLD FRONT WILL MOVE THROUGH THE GULF OF AMERICA THIS
WEEKEND AND ENTER THE NORTHWESTERN CARIBBEAN EARLY MON, REACHING
FROM NW HAITI TO NEAR THE NICARAGUA-COSTA RICA BORDER TUE MORNING.
EXPECT STRONG N WINDS AND RAPIDLY BUILDING SEAS BEHIND THIS FRONT.
..ATLANTIC OCEAN
HIGH PRESSURE DOMINATES THE TROPICAL ATLANTIC, WITH A NARROW RIDGE
EXTENDING ALONG ABOUT 27N FROM 55W INTO THE NW BAHAMAS TO SOUTH
CENTRAL FLORIDA. THIS PATTERN IS SUPPORTING MODERATE TO LOCALLY
FRESH WESTERLY WINDS AND SEAS OF 5-9 FT NORTH OF 28N AND WEST OF
55W, EXCEPT MODERATE TO FRESH S TO SW WINDS WEST OF 77W. MODERATE
OR WEAKER SW TO W WINDS PREVAIL N OF 25N BETWEEN 55W AND 35W,
WHERE SEAS ARE 6 TO 10 FT IN NW SWELL. MODERATE TO LOCALLY FRESH
EASTERLY WINDS AND SEAS OF 6-9 FT IN NW TO N SWELL ARE NOTED S OF
THE RIDGE, SOUTH OF 20N AND WEST OF 30W. DECAYING NW SWELL IS
PRODUCING ROUGH SEAS TO 10 FT NORTH OF 20N AND EAST OF 35W. IN
THE FAR EASTERN ATLANTIC, MODERATE TO FRESH NE WINDS AND ROUGH
SEAS ARE OCCURRING NORTH OF 20N AND EAST OF 25W. ELSEWHERE,
MODERATE OR WEAKER WINDS AND MODERATE SEAS ARE PREVALENT. DRY AND
VERY STABLE AIR FROM AFRICA IS SLOWLY SHIFTING WESTWARD AWAY FROM
THE W COAST AND HAS REACHED 30W.
FOR THE FORECAST WEST OF 55W, A NARROW RIDGE ALONG 27N WILL SHIFT
SLOWLY EASTWARD THROUGH THE WEEKEND, PRODUCING MODERATE TO
LOCALLY FRESH S TO SW WINDS OFFSHORE OF NORTHERN FLORIDA THROUGH
EARLY SUN. MODERATE OR WEAKER WINDS ARE EXPECTED ELSEWHERE THROUGH
SAT. A STRONG COLD FRONT WILL PUSH OFFSHORE OF THE SOUTHEASTERN
U.S. ON SUN, WITH STRONG TO GALE FORCE NW WINDS AND RAPIDLY
BUILDING SEAS BEHIND THE FRONT THROUGH EARLY MON. THE FRONT IS
EXPECTED TO REACH FROM NEAR BERMUDA TO CENTRAL CUBA MON MORNING,
AND FROM 31N60W TO THE NW COAST OF THE DOMINICAN REPUBLIC TUE
MORNING, WHILE WEAKENING. THE FRONT WILL STALL AND WEAKEN QUICKLY
FROM 29N55W TO THE CENTRAL DOMINICAN REPUBLIC ON WED.
