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
1700 UTC.
..SPECIAL FEATURES
ATLANTIC GALE WARNING: A COLD FRONT WILL MOVE ACROSS THE WATERS
BETWEEN NORTHEAST FLORIDA AND BERMUDA TONIGHT INTO SUNDAY. A
TIGHT PRESSURE GRADIENT WILL SUPPORT GALE FORCE WINDS ON EITHER
SIDE OF THE COLD FRONT SUN AFTERNOON, SOUTH AND SOUTHEAST OF
BERMUDA GENERALLY N OF 29N BETWEEN 55W AND 65W. STRONG TO NEAR-
GALE FORCE WINDS, ROUGH TO VERY ROUGH SEAS, AND SCATTERED TO
NUMEROUS THUNDERSTORMS ARE ALSO EXPECTED MAINLY ALONG AND AHEAD OF
THE FRONT, NORTH OF 26N. CONDITIONS WILL IMPROVE MON AS THE FRONT
WEAKENS AND HIGH PRESSURE BUILDS IN ITS WAKE.

..TROPICAL WAVES
AN EAST ATLANTIC TROPICAL WAVE IS ANALYZED ALONG 17W, SOUTH OF
16N. THE WAVE IS MOVING WESTWARD AT 10 TO 15 KT. SCATTERED
MODERATE CONVECTION IS NOTED FROM 02N TO 09N BETWEEN 10W AND 21W.
A CENTRAL ATLANTIC TROPICAL WAVE IS ALONG 61W, SOUTH OF 17N,
MOVING WESTWARD AT 15 TO 20 KT. SCATTERED MODERATE TO ISOLATED
STRONG CONVECTION IS OBSERVED FROM 05N TO 13N BETWEEN 57W AND
62W.
A CARIBBEAN TROPICAL WAVE IS ANALYZED ALONG 75W, SOUTH OF 16N,
MOVING WESTWARD AT 5 TO 10 KT. SCATTERED SHOWERS ARE SEEN NEAR THE
WAVE AXIS.
..MONSOON TROUGH/ITCZ
THE MONSOON TROUGH ENTERS THE ATLANTIC THROUGH THE COAST OF
GUINEA-BISSAU NEAR 11N16W AND CONTINUES SOUTHWESTWARD TO 06N22W.
THE ITCZ EXTENDS FROM 06N22W TO 04N51W. SCATTERED MODERATE
CONVECTION IS SEEN ALONG AND WITHIN 200 NM OF THE MONSOON TROUGH
AND ITCZ FROM 22W WESTWARD.
..GULF OF AMERICA
DIVERGENCE ALOFT ASSOCIATED WITH A SHARP UPPER LEVEL TROUGH OVER
THE WESTERN GULF AND A BROAD SURFACE TROUGH OVER THE CENTRAL TO SW
GULF COMBINE TO PRODUCE SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS OVER A THE EASTERN HALF OF THE BASIN. AT THE
SURFACE, A WEAK PRESSURE GRADIENT RESULTS IN MODERATE OR LIGHTER
WINDS AND SLIGHT SEAS. HOWEVER, STRONGER WINDS AND HIGHER SEAS
CAN OCCUR WITHIN STRONGER THUNDERSTORMS.
FOR THE FORECAST, THE ATLANTIC RIDGE EXTENDS ACROSS FLORIDA INTO
THE GULF REGION. THIS SYSTEM WILL SUSTAIN GENTLE TO MODERATE E TO
SE WINDS THROUGH MIDWEEK. THE EXCEPTION WILL BE EVENING PULSES OF
FRESH WINDS OFF THE NORTHERN YUCATAN AND IN THE CENTRAL GULF
THROUGH THE SAME PERIOD. A PRONOUNCED DEEP-LAYERED UPPER-LEVEL
TROUGH ACROSS THE WESTERN GULF COMBINED WITH A VERY WARM, HUMID
AND UNSTABLE AIRMASS WILL CONTINUE TO SUPPORT ROUNDS OF SHOWERS
AND THUNDERSTORMS, ACROSS THE CENTRAL AND EASTERN GULF THROUGH AT
LEAST SUN. FREQUENT LIGHTNING, WITH GUSTY WINDS AND LOCALLY ROUGH
SEAS ARE EXPECTED IN STRONG THUNDERSTORMS. MARINERS ARE URGED TO
KEEP UP TO DATE WITH THE LATEST FORECASTS.
..CARIBBEAN SEA
A FEW SHOWERS AND THUNDERSTORMS ARE ACTIVE OVER THE FAR SOUTHWEST
CARIBBEAN NEAR THE EASTERN EXTENSION OF THE EAST PACIFIC MONSOON
TROUGH. IN THE NW CARIBBEAN, SCATTERED MODERATE TO STRONG
CONVECTION IS DEVELOPING ALONG A SURFACE TROUGH ANALYZED FROM THE
GULF OF HONDURAS ALONG THE COASTS OF BELIZE AND THE EASTERN
YUCATAN PENINSULA. NO OTHER SIGNIFICANT CONVECTION IS OBSERVED AT
THIS TIME. A STRONG ATLANTIC RIDGE EXTENDS SOUTHWESTWARD INTO
THE CARIBBEAN, SUPPORTING FRESH TO STRONG EASTERLY TRADE WINDS AND
SEAS OF 6-8 FT IN THE SOUTH-CENTRAL CARIBBEAN, CONFIRMED BY
SCATTEROMETER AND ALTIMETER DATA FROM THIS MORNING. MODERATE TO
FRESH BREEZES AND MODERATE SEAS ARE FOUND IN THE REST OF THE BASIN
AWAY FROM THE LEE OF CUBA, WHERE LIGHT TO GENTLE WINDS AND SLIGHT
TO MODERATE SEAS PREVAIL.
FOR THE FORECAST, THE ATLANTIC RIDGE COMBINED WITH THE COLOMBIAN
LOW WILL SUPPORT MODERATE TO FRESH E TO SE TRADE WINDS ACROSS MOST
OF THE BASIN THROUGH THE EARLY PART OF THE NEXT WEEK, WITH FRESH
TO STRONG WINDS AND ROUGH SEAS OVER THE SOUTH-CENTRAL CARIBBEAN.
LOOKING AHEAD, THE AREA OF FRESH TO STRONG WINDS AND ROUGH SEAS
WILL EXPAND ACROSS THE CENTRAL CARIBBEAN TUE AND WED AS THE RIDGE
BUILDS NORTH OF THE AREA.
..ATLANTIC OCEAN
A STATIONARY FRONT EXTENDS ALONG 30-31N FROM NEAR 58W TO A 1012 MB
LOW NEAR 31N78W, WITH A DISSIPATING STATIONARY FRONT BETWEEN THE
LOW AND THE GA COAST. A SURFACE TROUGH EXTENDS FROM THE LOW TO THE
NORTHERN BAHAMAS, AND IS SUPPORTING SCATTERED MODERATE CONVECTION
ALONG AND EAST OF THE TROUGH. SW WINDS AHEAD OF THE FRONT,
GENERALLY N OF 27N BETWEEN 55W AND 63W ARE INCREASING TO FRESH TO
STRONG SPEEDS WHILE SEAS BUILD TO 7-9 FT. RIDGING PREVAILS ACROSS
MUCH OF THE REMAINING ATLANTIC. FRESH TO STRONG NE WINDS AND 6-9
FT SEAS PREVAIL N OF 14N AND E OF 25W, CONFIRMED BY SCATTEROMETER
DATA FROM THIS MORNING. MODERATE TO FRESH TRADES AND MODERATE SEAS
PREVAIL ACROSS MUCH OF THE ATLANTIC W OF 25W AND S OF 22N. THE
REMAINDER OF THE BASIN AWAY FROM ANY FRONTS OR OTHER FEATURES IS
SEEING GENTLE TO MODERATE OR WEAKER WINDS AND SLIGHT TO MODERATE
SEAS.
FOR THE FORECAST WEST OF 55W, A FEW THUNDERSTORMS ARE ACTIVE NEAR
A 1012 MB LOW PRESSURE AREA LOCATED OFF NORTHEAST FLORIDA. THE
LOW IS ALONG A STATIONARY FRONT EXTENDING FROM 31N58W TO THE LOW
CENTER. FRESH TO STRONG WINDS AND ROUGH SEAS WILL FOLLOW THE LOW
PRESSURE AS IT MOVES EASTWARD THROUGH TONIGHT AHEAD OF A
REINFORCING COLD FRONT MOVING INTO THE AREA. THE COMBINED FRONTS
WILL SHIFT EASTWARD, REACHING FROM BERMUDA TO THE NORTHERN BAHAMAS
BY EARLY SUN. EXPECT STRONG WINDS AND ROUGH TO VERY ROUGH SEAS
ALONG AND AHEAD OF THE FRONT NORTH OF 25N SUN, WITH GALE-FORCE
WINDS SOUTH OF BERMUDA NEAR 30N63W BY SUN AFTERNOON. THE FRONT
WILL WEAKEN AND STALL FROM 31N57W TO 27N65W BY EARLY MON. WINDS
AND SEAS DIMINISH WEST OF THE FRONT AS HIGH PRESSURE BUILDS
BETWEEN NORTHEAST FLORIDA AND BERMUDA. LOOKING AHEAD, A SECOND LOW
PRESSURE AREA AND ACCOMPANYING FRONT MAY MOVE OFF NORTHEAST
FLORIDA BY LATE MON AND SHIFT EASTWARD TOWARD BERMUDA THROUGH MID
WEEK, ACCOMPANIED BY FRESH TO STRONG WINDS AND ROUGH SEAS OVER THE
WATERS NORTH OF 27N.
