    Tropical Weather Discussion for North America, Central America
    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 0930 UTC.

    ...SPECIAL FEATURES...

    Atlantic Gale Warning: A cold front will move offshore the SE
    U.S. coast today, then move slowly SE and reach from 31N72W to
    South Florida by Tue, then stall from Bermuda to the Florida
    Straits Wed. Low pressure is forecast to form along the front in
    the vicinity of the Bahamas on Tue, then accelerate NE along the
    boundary and out of the basin toward Bermuda by Wed. As the
    pressure gradient increases behind this low and strong high
    pressure building into the SE U.S., already strong NE winds N and
    W of the front will increase further, with gales developing Tue
    afternoon offshore NE Florida, then spreading east between the
    Bahamas and Bermuda Tue night into Wed. Very rough seas in excess
    of 15 kt are likely in the area of gales. With the frontal
    boundary remaining nearly stationary late this week, conditions
    will be slow to improve.

    Hurricane Center at website:

    ...MONSOON TROUGH/ITCZ...

    The monsoon trough reaches the Atlantic through the coast of
    Sierra Leone near 09N13W and continues southwestward to 04N21W.
    The ITCZ extends from 04N21W to 01N45W. Only isolated convection
    exists within about 150 nm of both of these features.

    ...GULF OF MEXICO...

    A cold front extends from Apalachicola Bay to just north of
    Veracruz, Mexico. Strong to near gale force N winds are N of the
    front within 150 nm of the Mexican coast as well as with 180 nm of
    the Texas and Louisiana coasts. Scattered moderate convection is
    noted ahead of the front from the Bay of Campeche northward to
    around 27N between 91W and 96W. Seas where the strong winds exist
    are 8 to 11 ft. S and E of the front, gentle winds and slight seas prevail.

    For the forecast, the cold front will move slowly SE and reach
    from SW Florida to the eastern Bay of Campeche tonight, then drift
    slowly SE of the basin Tue and Tue night. Thunderstorms with
    locally gusty winds will accompany the front. Strong NE winds and
    rough seas will continue in the western Gulf behind the front
    through tonight, then strong NE winds will develop in the NE
    basin, as low pressure develops in the Atlantic after the front
    exits the Gulf of Mexico. Conditions will improve some Fri and
    Fri night as high pressure from the eastern U.S builds
    southwestward toward the northern Gulf.

    ...CARIBBEAN SEA...

    A benign trade wind dominant weather pattern prevails through the
    basin, with moderate to fresh E winds through the central and
    eastern basin, and gentle NE winds in the west. Moderate seas are
    present, except for slight in the NW basin.

    For the forecast, a trough oriented north of Haiti will meander
    into mid-week, disrupting the typical pressure gradient through
    the basin and leading to mainly gentle winds over the western
    basin, with moderate to fresh winds over the eastern Caribbean. By
    Wed night, strong high pressure building south toward the region
    will replace the trough and winds in the south-central Caribbean
    will increase to fresh to strong.

    ...ATLANTIC OCEAN...

    See Special Features section above for information on a Gale
    Warning that has been issued for portions of the SW Atlantic
    starting Tuesday.

    A broad subtropical ridge covers the region and support moderate
    to fresh NE to E winds across the central subtropical waters along
    with seas to 7 ft. Over the SW N Atlantic waters, rough seas in
    decaying NE to E swell exist E of the Bahamas. A weak trough along
    70W is inducing scattered moderate convection N of the Antilles to
    24N between 62W and 77W.

    For the forecast west of 55W, hazardous marine conditions are
    expected this week NW of a line from 31N60W to the SE Bahamas, as
    very rough seas and gale conditions will impact some areas.
    Details can be found in the Special Features section above.
