    Gulf of Mexico, 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 0600 UTC surface analysis and satellite imagery through

    ...SPECIAL FEATURES...

    Caribbean Gale Warning: Widespread fresh E trade winds and rough
    seas will occur across the southwestern, central and eastern
    Caribbean through this weekend as a strong pressure gradient
    prevails between low pressure over northwestern Colombia and high
    pressure in the central Atlantic. Winds will pulse to gale force
    early this morning offshore of NW Colombia, with winds reaching
    near-gale force each night and early morning thereafter into Sun.
    Very rough seas will occur near and to the west of the highest
    winds.

    Gulf of Mexico Gale Warning: A mixed cold and stationary front
    extending from central Florida to 24N95W to the western Bay of
    Campeche will stall today. Strong to near-gale force winds will
    occur to the north and west of this front early this morning, and
    winds will briefly reach gale force offshore of Veracruz. Very
    rough seas up to 15 ft will occur near the gale force winds. Winds
    and seas in this region will diminish from north to south this
    morning.

    ...MONSOON TROUGH/ITCZ...

    The monsoon trough enters the Atlantic near 05N09W and extends to
    01S18W. The ITCZ continues from 01S18W to 01S37W. Scattered
    moderate convection is occurring south of 06N and east of 15W, and
    south of 04N and west of 30W.

    ...GULF of Mexico...

    Please refer to the special features section for information
    regarding a Gale Warning in the southwestern Gulf of Mexico this morning.

    A cold front has been analyzed from Tampa Bay to 27N86W, and a
    stationary front continues to 24N95W to the western Bay of
    Campeche. Fresh to strong NE to E winds and rough seas are
    occurring to the north of these fronts in the northern Gulf of
    Mexico. Strong to near-gale force N winds are occurring in the
    far southwestern Gulf, with gale force winds noted just offshore
    of Veracruz. Rough seas are occurring to the west of the
    stationary front, with locally very rough seas of 12 to 15 ft
    noted near the gale force winds. Elsewhere, a trough has been
    analyzed in the eastern Bay of Campeche, and moderate to locally
    fresh SE to NE winds are noted surrounding this feature.
    Otherwise, moderate to locally fresh N winds prevail in the
    southeastern Gulf.

    For the forecast, the aforementioned cold and stationary fronts
    will stall today. Strong to near-gale force winds will occur to
    the north and west of this front early this morning, and winds
    will briefly reach gale force offshore of Veracruz. Very rough
    seas up to 15 ft will occur near the gale force winds. Winds and
    seas in this region will diminish from north to south this
    morning. The aforementioned front will lift northward this
    afternoon into Sat, supporting moderate to fresh S to SE winds
    across much of the basin. Winds will increase to strong speeds
    across the northwestern and north-central Gulf of Mexico by Sat
    morning as a tightening pressure gradient develops between the
    front and strengthening low pressure in the central United States.
    Looking ahead, the next cold front will enter the northwestern
    basin late Sat into Sun, promoting fresh to strong N winds and
    rough seas west of 90W. Gale force winds will be possible offshore
    of Veracruz on Sun behind the front.

    ...CARIBBEAN SEA...

    Please refer to the special features section for information
    regarding a Gale Warning in the south-central Caribbean offshore
    of Colombia this morning.

    A tight pressure gradient prevails between high pressure in the
    central Atlantic and the eastern extent of the Pacific monsoon
    trough in the south-central Caribbean. This pattern is supporting
    widespread fresh E winds through much of the basin, with strong
    winds occurring in the central Caribbean, through the Windward
    Passage, in the Gulf of Honduras and through the Atlantic Passages
    into the northeastern Caribbean. Gale force winds are noted just
    offshore of Colombia. Rough seas cover the southwestern, central
    and eastern basin, with locally very rough seas occurring near and
    to the west of the gale force winds.

    For the forecast, widespread fresh E trade winds and rough seas
    will occur across the southwestern, central and eastern Caribbean
    through this weekend. Winds will pulse to gale force early this
    morning offshore of NW Colombia, with winds reaching near-gale
    force each night and early morning thereafter into Sun. Very rough
    seas will occur near and to the west of the highest winds.
    Pulsing strong winds are expected across the central Caribbean
    through this weekend, as well as in the Gulf of Venezuela, through
    the Atlantic Passages, in the lee of Cuba and Hispaniola, and in
    the Gulf of Honduras. Otherwise, moderate to fresh winds will
    occur in the northwestern Caribbean through this weekend. Looking
    ahead, a decreasing pressure gradient between the Colombian low
    and high pressure in the western and central Atlantic will support
    moderate to fresh trade winds and locally rough seas across the
    basin into early next week, with locally strong winds occurring
    offshore of Colombia.

    ...ATLANTIC OCEAN...

    A cold front extends from 31N21W to 25.5N33W in the eastern
    Atlantic. Rough seas are occurring along and to the north of this
    front, and seas of 12 to 15 ft are noted north of 27.5N.
    Elsewhere, a cold front is pushing off the southeastern coast of
    the United States, extending from 31N77W to central Florida.
    Moderate N winds are occurring north of this front. Otherwise, the
    remainder of the basin is dominated by a 1030 mb high centered
    near 29N57W. Moderate to fresh E trade winds and rough are
    occurring south of 25N, with locally strong winds noted south of
    20N and west of 40W. Locally very rough seas are occurring near
    the strongest winds.

    For the forecast, fresh to strong E trade winds are expected
    south of 25N, including through the Atlantic Passages into the
    Caribbean through late tonight, with fresh to pulsing strong E
    winds expected into early next week. A long-period E swell will
    support rough seas in this region, with locally very rough seas
    possible east of the Windward Islands through Sat. A strong cold
    front extending from 31N77W to central Florida will progress
    southeastward today, leading to fresh to strong NE to E winds
    behind the front, generally north of 28.5N and west of 60W. Rough
    seas will occur in tandem with these winds. The cold front will
    stall along 28N on Sat, and moderate to fresh NE to E winds will
    prevail north of this boundary. Looking ahead, fresh to strong S
    to SW winds and rough seas will develop west of 70W off the coast
    of Florida on Sun ahead of a very strong storm system moving
    through the eastern United States. A cold front associated with
    this system will exit the SE United States late Sun and reach from
    Bermuda to the Florida Straits by Mon afternoon, then drift SE
    and weaken considerably through Tue.
