MAURITANIA NEAR 18N16W SOUTHWEST TO 06N29W. THE ITCZ EXTENDS FROM
06N30W TO 09N49W, WHERE IT BREAKS FOR A TROPICAL WAVE. THE ITCZ
RESUMES AT 09N53W THEN TO 08N60W ALONG COASTAL VENEZUELA. SCATTERED
MODERATE CONVECTION IS FROM 05N-11N BETWEEN 25W-38W. ISOLATED

..GULF OF AMERICA
A 1020 MB HIGH PRESSURE IS CENTERED OVER THE N GULF NEAR 29N88W.
WINDS ACROSS THE GULF ARE GENERALLY LIGHT TO MODERATE EXCEPT FOR
ISOLATED STRONG E WINDS OVER THE BAY OF CAMPECHE. SEAS ARE 2-4 FT.
ISOLATED MODERATE CONVECTION IS OCCURRING OVER THE STRAITS OF
FLORIDA THIS AFTERNOON.
FOR THE FORECAST, THE HIGH PRESSURE OVER THE NE GULF WILL SHIFT TO
THE CENTRAL GULF. THE HIGH PRESSURE WILL PROVIDE FOR A LIGHT TO
GENTLE WIND FLOW ACROSS THE BASIN INTO THE EARLY PART OF NEXT
WEEK, EXCEPT FOR PULSING MODERATE TO FRESH WINDS OFF THE YUCATAN
PENINSULA THROUGH THE WEEKEND.
..CARIBBEAN SEA
A MODERATE PRESSURE GRADIENT BETWEEN LOW PRESSURE OVER NORTHERN
SOUTH AMERICA AND HIGH PRESSURE NORTH OF THE AREA IS FORCING FRESH
TO STRONG TRADES OVER THE CENTRAL CARIBBEAN WITH SEAS 6-9 FT.
ELSEWHERE WINDS ARE GENTLE TO MODERATE WITH SEAS 3-5 FT. SCATTERED
MODERATE AND ISOLATED STRONG CONVECTION IS OCCURRING FROM 10N-17N
WEST OF 76W ASSOCIATED WITH A TROPICAL WAVE. ADDITIONALLY, AN

MODERATE SEAS WILL PREVAIL ELSEWHERE.
..ATLANTIC OCEAN
THE BERMUDA-AZORES HIGH WELL NORTH OF THE AREA ALONG WITH LOWER
PRESSURE OVER THE ITCZ AND THE MONSOON TROUGH IS FORCING ONLY
MODERATE TO ISOLATED FRESH TRADES WEST OF 30W WITH SEAS OF 4-7 FT.
A LARGER PRESSURE GRADIENT FARTHER EAST IS FORCING FRESH TO
LOCALLY STRONG NE WINDS WITH SEAS 7-9 FT NORTH OF 20N EAST OF
30W. AN UPPER-LEVEL LOW IS CAUSING ISOLATED MODERATE CONVECTION
NORTH OF 24N BETWEEN 61W-78W.
FOR THE FORECAST WEST OF 55W, A TROUGH OFF THE EAST COAST OF
FLORIDA WILL DRIFT WEST INTO THE PENINSULA TODAY. SCATTERED
THUNDERSTORMS WILL ACCOMPANY THE TROUGH ACROSS THE BAHAMAS. FRESH
TRADE WINDS ARE EXPECTED OFFSHORE HISPANIOLA, INCLUDING APPROACHES
