HISPANIOLA. A REINFORCING FRONT EXTENDS FROM 31N55W TO CENTRAL
CUBA. GALE-FORCE WINDS IN ASSOCIATION WITH THESE FRONT ARE
CURRENTLY NORTH OF 27N BETWEEN 43W AND 66W. ROUGH TO VERY ROUGH
SEAS ACCOMPANY THE FRONT AS DESCRIBED IN GREATER DETAIL BELOW. THE
FRONTS WILL MERGE TODAY, AND QUICKLY SHIFT EASTWARD, WITH GALE-
FORCE WINDS CONTINUING THROUGH EARLY SAT. THE FRONT AND ANY
REMAINING ASSOCIATED GALE-FORCE WINDS WILL SHIFT NORTHEAST AND
EAST OF THE AREA SAT AFTERNOON.
ANOTHER COLD FRONT WILL IMPACT THE SW N ATLANTIC WATERS,

FORCE WINDS MAINLY EAST OF THE FRONT NORTH OF 29N. BY SUN
EVENING, THE FRONT WILL REACH FROM NEAR 31N47W TO THE CENTRAL
BAHAMAS WITH WINDS DIMINISHING BELOW GALE- FORCE. THIS SYSTEM WILL
GENERATE A NEW SET OF LARGE NW SWELL, WHICH WILL REINFORCE THE
SWELL GENERATED BY THE FIRST FRONT.
GULF OF MEXICO GALE WARNING: A 1006 MB LOW IS CENTERED NEAR
29.5N94W, WITH ASSOCIATED COLD FRONT EXTENDING SW TO NEAR TAMPICO,
MEXICO. GALE- FORCE WINDS ARE EAST OF THE LOW CENTER, WHERE SEAS
ARE IN THE 8-13 FT RANGE. THE GALE FORCE WINDS WILL DIMINISH
TODAY, WITH FREQUENT GUSTS TO GALE FORCE CONTINUING WITHIN 60 NM
OF THE COAST THROUGH EARLY TONIGHT. THE LOW WILL DRAG A COLD
FRONT ACROSS MOST OF THE GULF THROUGH SAT. FRESH TO STRONG WINDS
AND ROUGH SEAS WILL FOLLOW THE FRONT, REACHING GALE- FORCE OFF
TAMPICO,MEXICO AND VERACRUZ, MEXICO TODAY. WINDS WILL DIMINISH
BELOW GALE-FORCE BY SAT.
ATLANTIC SIGNIFICANT SWELL EVENT: LARGE LONG-PERIOD NORTHWEST
SWELL WITH WAVE PERIODS OF 12 TO 14 SECONDS CONTINUES TO
PROPAGATE ACROSS THE SUBTROPICAL ATLANTIC WATERS. SEAS GREATER
THAN 12 FT ASSOCIATED TO THIS SWELL COVER THE WATERS N OF 25N
BETWEEN 30W AND 75W. THESE CONDITIONS WILL PROPAGATE EASTWARD
ACROSS THE ATLANTIC WATERS, BEING REINFORCED BY A SET OF NEW NW
SWELL AS DISCUSSED ABOVE. SEAS WILL PEAK IN EXCESS OF 20 FT NORTH
OF 27N BETWEEN 47W AND 60W TONIGHT. SEAS OF 12 FT OR GREATER ARE
FORECAST TO CONTINUE SPREADING SOUTHEASTWARD THROUGH AT LEAST THE
