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
EQUATOR TO 31N. THE FOLLOWING INFORMATION IS BASED ON SATELLITE
IMAGERY, WEATHER OBSERVATIONS, RADAR AND METEOROLOGICAL ANALYSIS.
BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1610 UTC.
..MONSOON TROUGH/ITCZ
THE MONSOON TROUGH AXIS ENTERS THE ATLANTIC THROUGH THE BORDER OF
SIERRA LEONE AND LIBERIA NEAR 06N10W AND CONTINUES SOUTHWESTWARD
TO 03N13W, WHERE THE ITCZ BEGINS AND CONTINUES TO 01S49W ALONG
THE COAST OF BRAZIL. SCATTERED MODERATE ISOLATED STRONG CONVECTION
IS NOTED FROM 01N TO 06N BETWEEN 10W AND 27W.
GULF OF AMERICA...
1020 MB HIGH PRESSURE CENTERED IN THE E GULF PROVIDES FOR GENTLE
TO MODERATE ANTICYCLONIC WINDS AND 2-4 FT SEAS ACROSS THE BASIN.
FOR THE FORECAST, HIGH PRESSURE CENTERED OVER THE EASTERN GULF WILL
MAINTAIN GENTLE TO MODERATE SE WINDS AND SLIGHT TO MODERATE SEAS
ACROSS THE WESTERN GULF, AND LIGHT TO GENTLE BREEZES OVER THE
EASTERN GULF THROUGH MID-WEEK. A TROUGH OVER THE BAY OF CAMPECHE
WILL SUPPORT OCCASIONAL MODERATE TO FRESH WINDS OFF THE NORTHERN
AND WESTERN COASTS OF THE YUCATAN PENINSULA MAINLY AT NIGHT
THROUGH MID-WEEK.
CARIBBEAN SEA...
A TROUGH EXTENDS FROM SE PUERTO RICO TO 1011 MB LOW PRESSURE NEAR
13N74W TO THE COAST OF COLOMBIA NEAR 11N74W. FRESH TO LOCALLY
STRONG NE WINDS PERSIST NORTH OF THE SURFACE TROUGH, INCLUDING
WITHIN THE MONA PASSAGE, WINDWARD PASSAGE, AND LEE OF CUBA. SEAS
ARE 4-7 FT IN THESE REGIONS. ELSEWHERE IN THE WESTERN CARIBBEAN,
NE WINDS ARE GENTLE TO MODERATE WITH 4-6 FT SEAS. IN THE CENTRAL
AND EASTERN CARIBBEAN SOUTH AND EAST OF THE TROUGH, TRADES ARE
LIGHT TO GENTLE WITH 2-4 FT SEAS.
FOR THE FORECAST, BUILDING HIGH PRESSURE OVER THE WESTERN
ATLANTIC WILL SUPPORT FRESH NE WINDS SOUTH OF CUBA, THE WINDWARD
PASSAGE AND JUST SOUTH OF HISPANIOLA INTO MON NIGHT. AS THE HIGH
PRESSURE MOVES SLIGHTLY EASTWARD MON, FRESH TO STRONG WINDS AND
MODERATE TO ROUGH SEAS WILL START TO PULSE NIGHTLY OFFSHORE
COLOMBIA.
ATLANTIC OCEAN...
A COLD FRONT EXTENDS FROM 1006 MB LOW PRESSURE NEAR 32N57W TO
EASTERN PUERTO RICO. SATELLITE SCATTEROMETER INDICATES STRONG TO
NEAR-GALE FORCE SE WINDS NORTH OF 22N AND EAST OF THE FRONT TO
52W. NORTH OF 25N AND WEST OF THE FRONT TO 65W, FRESH TO STRONG
NW WINDS ARE EVIDENT ON SATELLITE SCATTEROMETER DATA. SEAS ARE
8-11 FT NORTH OF 22N BETWEEN 50W AND 70W. SCATTERED MODERATE
CONVECTION IS NORTH OF 25N BETWEEN 52W AND 57W. IN THE EASTERN
ATLANTIC, SEAS OF 8-11 FT ARE ANALYZED ACROSS THE BASIN EAST OF
45W IN NE SWELL GENERATED BY A WEAKENING 999 MB LOW NEAR THE
CANARY ISLANDS. SEAS RANGE FROM 12-14 FT NORTH OF 27N BETWEEN 20W
AND 28W. WINDS IN THE FAR NE ATLANTIC REMAIN NEAR FRESH SPEEDS
ALONG THE SOUTHERN SIDE OF THE LOW PRESSURE. ELSEWHERE, MODERATE
OR WEAKER WINDS AND 4-7 FT SEAS PREVAIL ACROSS THE ATLANTIC.
FOR THE FORECAST WEST OF 55W, FRESH TO STRONG WINDS AND ROUGH
SEAS ON BOTH SIDES OF THE AFOREMENTIONED COLD FRONT NORTH OF 25N
WILL CONTINUE TO AFFECT THE OFFSHORE WATERS FROM WEST TO EAST INTO
EARLY MON AS THE FRONT CONTINUES TO MOVE EASTWARD. THE COLD FRONT
IS FORECAST TO REACH FROM 31N55W TO VIRGIN ISLANDS BY THIS
EVENING, THEN WILL MOVE INTO THE CENTRAL ATLANTIC MON THROUGH TUE
WHILE GRADUALLY DISSIPATING. LOOKING AHEAD, A NEW COLD FRONT IS
FORECAST TO ENTER THE OFFSHORE WATERS BETWEEN NORTHEAST FLORIDA
AND BERMUDA MON NIGHT INTO TUE, FOLLOWED BY FRESH TO STRONG NE TO
E WINDS AND ROUGH TO VERY SEAS. THESE MARINE CONDITIONS ARE
FORECAST TO AFFECT MOST OF THE WATERS NORTH OF 28N INTO MID-WEEK
BEFORE STARTING TO DIMINISH AS THE FRONT LIFTS NORTHWARD.
