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 0000 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
0550 UTC.
..TROPICAL WAVES
A TROPICAL WAVE IS ALONG 35W, FROM 10N TO 22N, MOVING WESTWARD
NEAR 10 KT. A TIGHT GRADIENT BETWEEN THE WAVE AND HIGH PRESSURE TO
ITS NORTH IS PRODUCING FRESH TO STRONG EASTERLY WINDS FROM 21N TO
26N BETWEEN 28W AND 36W. SEAS WITH THESE WINDS ARE 8 TO 11 FT
(2.5 TO 3.5 M). SATELLITE IMAGERY SHOWS SCATTERED MODERATE TO
ISOLATED STRONG CONVECTION FROM 18N TO 26N BETWEEN 27W AND 32W.
A TROPICAL WAVE IS NEAR 48W, FROM 10N TO 20N, MOVING WESTWARD AT
10 TO 15 KT. SCATTERED MODERATE CONVECTION IS FROM 15N TO 21N
BETWEEN 41W AND 49W.
..MONSOON TROUGH/ITCZ
THE MONSOON TROUGH AXIS ENTERS THE ATLANTIC NEAR 13N17W TO
19N34W TO 12N48W. THE ITCZ EXTENDS FROM 11N52W TO 09N60W. SCATTERED
MODERATE CONVECTION IS FROM 04N TO 11N BETWEEN 25W AND 36W.
..GULF OF AMERICA
A 1018 MB HIGH IS CENTERED OVER SOUTHERN ALABAMA AND EXTENDS A
BROAD RIDGE SOUTH-SOUTHWESTWARD ACROSS THE BASIN. RECENT
SCATTEROMETER DATA SHOW GENTLE TO MODERATE NORTHEAST TO EAST
WINDS ACROSS THE EASTERN HALF OF THE GULF S OF 28N, AND EAST TO
SOUTHEAST WINDS OF THE SAME SPEED W OF 90W. SEAS BASIN-WIDE ARE
IN THE RANGE OF 1 TO 5 FT. FAIR SKIES PREVAIL.
FOR THE FORECAST, HIGH PRESSURE OVER THE NORTH-CENTRAL GULF WILL
SUPPORT E TO SE WINDS AND MODERATE SEAS FROM THE FLORIDA STRAITS
TO THE TEXAS COAST, AND GENTLE BREEZES AND SLIGHT SEAS ELSEWHERE.
A COLD FRONT IS EXPECTED TO ENTER THE NORTHWEST GULF FRI NIGHT,
AND REACH FROM SOUTHWEST FLORIDA TO THE FAR SOUTHWEST GULF BY SAT
NIGHT. STRONG TO NEAR-GALE FORCE WINDS AND ROUGH SEAS WILL FOLLOW
THE FRONT, WITH GALES POSSIBLE OFF THE COAST OF MEXICO BETWEEN
TAMPICO AND COATZACOALCOS LATE FRI NIGHT INTO SUN.
..CARIBBEAN SEA
A MIDDLE-LEVEL LOW IS SUPPORTING WIDELY SCATTERED SHOWERS IN THE
LEE SIDE OF CUBA ADJACENT WATERS, AND IN THE GULF OF HONDURAS
WHILE AN UPPER-LEVEL LOW OVER THE EASTERN HALF OF THE CARIBBEAN IS
SUPPORTING SCATTERED HEAVY SHOWERS AND ISOLATED TSTMS OVER
HISPANIOLA AND ITS ADJACENT WATERS, INCLUDING THE WINDWARD PASSAGE
AND THE MONA PASSAGE. A RECENT SCATTEROMETER PASS SHOW FRESH TO
STRONG ESE WINDS S OF HAITI AND IN THE WINDWARD PASSAGE.
ELSEWHERE, WINDS ARE MODERATE OR WEAKER, WITH SEAS FLUCTUATING
BETWEEN 3 TO 5 FT.
FOR THE FORECAST, SCATTERED SHOWERS AND THUNDERSTORMS WILL BE
ACTIVE ACROSS THE CENTRAL CARIBBEAN THROUGH TONIGHT, ASSOCIATED
WITH AN UPPER-LEVEL LOW. FRESH E TO SE WINDS WILL PERSIST NORTH OF
13N SOUTH AND SOUTHWEST OF JAMAICA THROUGH MID WEEK, NORTH OF
BROAD LOW PRESSURE OVER THE SOUTHWEST CARIBBEAN. TRADE WINDS WILL
INCREASE ALONG WITH BUILDING SEAS OVER THE SOUTH-CENTRAL CARIBBEAN
AS HIGH PRESSURE BUILDS OVER THE WESTERN ATLANTIC.
..ATLANTIC OCEAN
SURFACE RIDGING ANCHORED BY A 1019 MB IN NORTH CAROLINA, AND A
1018 MB HIGH IN SOUTHERN ALABAMA IS STARTING TO BUILD OVER THE SW
N ATLANTIC WATERS JUST N OF THE BAHAMAS AND WEST OF A COUPLE OF
SURFACE TROUGHS THAT LINGER BETWEEN 53W AND 68W. THE REMAINDER
SUBTROPICAL CENTRAL AND EASTERN ATLANTIC IS UNDER THE INFLUENCE OF
THE AZORES HIGH, WHICH IS SUPPORTING MODERATE TO FRESH NE WINDS
AND MODERATE SEAS TO 6 FT BETWEEN THE COAST OF NW AFRICA AND 26W,
INCLUDING THE CANARY ISLANDS. MODERATE OR WEAKER WINDS AND
MODERATE TO SLIGHT SEAS DOMINATE ELSEWHERE N OF 20N AND W OF 26W.
FOR THE FORECAST WEST OF 55W, A COLD FRONT WILL MOVE SOUTHWARD
INTO THE WATERS EAST OF 75W INTO WED, THEN STALL AND DISSIPATE
ALONG 29N THROUGH THU. A STRONGER COLD FRONT WILL MOVE INTO THE
WATERS OFF NORTHEAST FLORIDA BY LATE FRI NIGHT INTO EARLY SAT
MORNING, AND REACH FROM BERMUDA TO SOUTH FLORIDA BY LATE SAT.
STRONG TO NEAR-GALE FORCE WINDS AND ROUGH SEAS WILL FOLLOW THE
FRONT.
