SEAS GIVEN AS SIGNIFICANT WAVE HEIGHT, WHICH IS THE AVERAGE
HEIGHT OF THE HIGHEST 1/3 OF THE WAVES. INDIVIDUAL WAVES MAY BE
MORE THAN TWICE THE SIGNIFICANT WAVE HEIGHT.
SYNOPSIS FOR CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM
07N TO 19N W OF 55W
SYNOPSIS
A TROPICAL WAVE ALONG 67W WILL MOVE ACROSS THE
EASTERN CARIBBEAN THROUGH TONIGHT, ACROSS THE CENTRAL CARIBBEAN
MON THROUGH TUE, AND THE WESTERN CARIBBEAN TUE NIGHT THROUGH THU
NIGHT. EXPECT FRESH WINDS OVER THE CENTRAL CARIBBEAN MON THROUGH
TUE IN THE WAKE OF THE TROPICAL WAVE. SCATTERED SHOWERS AND
ISOLATED THUNDERSTORMS WILL ACCOMPANY THE WAVE. ANOTHER TROPICAL
WAVE IS EXPECTED TO ENTER THE EASTERN CARIBBEAN TUE OR WED.
FRESH TO STRONG WINDS WILL PULSE IN THE S-CENTRAL WATERS THROUGH
MID- WEEK. OTHERWISE, GENTLE TO MODERATE TRADES, AND MOSTLY
MODERATE SEAS WILL REMAIN THROUGH THE WEEK, EXCEPT SLIGHT TO

SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
A PAIR OF SURFACE TROUGHS OVER THE SW N ATLANTIC
SUPPORT ACTIVE SHOWERS AND THUNDERSTORMS MAINLY N OF 21N BETWEEN
57W AND 76W, WITH MODERATE TO FRESH NE WINDS OVER THE FAR NW
OFFSHORES. THESE CONDITIONS WILL DIMINISH AND SUBSIDE TONIGHT AS
THE TROUGHS WEAKEN. THE REMNANTS OF THE FRONT MAY LINGER OVER
THE WATERS OFFSHORE THE SE U.S. THROUGH THE WEEK. ATLANTIC HIGH
PRESSURE WILL GENERALLY MAINTAIN MODERATE WINDS AND SEAS
ELSEWHERE ACROSS THE REGION THROUGH THE WEEK. LOOKING AHEAD, A
TROPICAL WAVE OVER THE EASTERN TROPICAL ATLANTIC IS LIKELY TO
DEVELOP INTO A TROPICAL DEPRESSION DURING THE MIDDLE TO LATTER
PART OF THIS WEEK AS THE SYSTEM MOVES WEST-NORTHWESTWARD OVER
THE CENTRAL TROPICAL ATLANTIC. REGARDLESS OF DEVELOPMENT, EXPECT
INCREASING WINDS AND BUILDING SEAS OVER THE SE WATERS BY THE END
OF THE WEEK.
