Tropical Weather Discussion for North America, Central America
Gulf of America, 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 0000 UTC surface analysis and satellite imagery through
0325 UTC.
...TROPICAL WAVES...
An eastern Atlantic tropical wave is along 28W, south of 19N,
moving westward at 10-15 kt. A 1011 mb low pressure is analyzed
along the wave and monsoon trough near 12N28W. The broad system
is producing a large area of showers and thunderstorms, mainly
from 07N to 17N and between 20W and 33W. A recent scatterometer
satellite pass showed fresh to strong cyclonic winds associated
with this feature.
Another eastern Atlantic tropical wave is along 37W, south of 19N,
moving westward at 10-15 kt. Scattered moderate to isolated strong
convection is observed from 06N to 16N and between 33W and 46W.
A western Caribbean tropical wave is along 87W, south of 19N,
moving westward at 10-15 kt. The wave continues to interact with
an upper-level low over the NW Caribbean, and is supporting
scattered moderate to isolated strong convection over much of the
NW Caribbean. Diurnal heating and the features described are also
enhancing convection over Central America.
...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic through the coast of
Mauritania near 17N16W and continues southwestward to a 1011 mb
low near 12N28W and then to a 1012 mb low near 10N40W and to
07N44W. The ITCZ extends from 07N44W to 05N52W. Aside from the
convection associated with the tropical waves, convection is
limited elsewhere.
...GULF OF AMERICA...
A cold front extends from the Florida panhandle near Apalachicola
south and southwest to 24N90W and 23N97W. Scattered moderate to
isolated strong convection is found ahead of the front over the
eastern Gulf waters. A surface trough is analyzed over Yucatan and
extending northward to 25N86W. A few showers are also evident near
these trough, however, the strongest convection is occurring over
the Yucatan peninsula.
The moderate pressure gradient between the high pressure over the
southern United States and the aforementioned cold front support
moderate to locally fresh easterly winds over much of the NW and
north- central Gulf, along with moderate seas. Elsewhere, moderate
or lighter winds and moderate seas prevail.
For the forecast, fresh SW winds and scattered thunderstorms will
persist over the NE Gulf through tonight. The aforementioned front
will move across the southeast Gulf through mid week, while
lifting northward as a dissipating warm front over the western
Gulf. High pressure will build behind the front over the north-
central Gulf, supporting E to SE winds and moderate seas from the
Florida Straits to the Texas coast by mid week, and gentle breezes
and slight seas elsewhere.
...CARIBBEAN SEA...
Please read the Tropical Waves section for details on an active
tropical wave in the western Caribbean.
High pressure north of the islands extends into the Caribbean,
forcing moderate to locally strong easterly trade winds and
moderate to locally rough seas across much of the basin. The
strongest winds and highest seas are found off Colombia. A broad
upper-level low approaching the Leeward Islands is producing
scattered showers and thunderstorms over the eastern Caribbean,
affecting much of the Lesser Antilles.
For the forecast, moderate to fresh trade winds and moderate seas
will persist across the eastern and central Caribbean through the
early part of the week, with fresh to strong E winds and rough
seas across the Windward Passage and off Colombia. These winds and
seas will diminish through mid week as the high pressure shifts
eastward ahead of a cold front moving through the Gulf.
...ATLANTIC OCEAN...
A cold front enters the tropical Atlantic near 31N49W and continues
southwestward to 28N55W, followed by a stationary front to 26N61W
and then northwestward to 31N69W. A few showers are noted near
these boundaries. Meanwhile, showers and isolated thunderstorms
are evident off NE Florida ahead of a cold front moving across the
eastern Gulf of America. The modest pressure gradient between a
strong ridge over the NW Atlantic and the aforementioned front and
a trough north of the Leeward Islands sustain moderate to locally
strong anticyclonic winds over much of the SW North Atlantic, west
of 60W and north of the front west of 50W.
The remainder of the Atlantic forecast region is under the
influence of a 1025 mb high pressure located just SE of the
Azores. The pressure gradient between its associated ridge and
lower pressures in the vicinity of the monsoon trough supports
moderate to locally strong NE to E winds N of the monsoon trough
to about 26N and east of 40W. Elsewhere, moderate or weaker winds
and moderate seas prevail.
For the forecast west of 55W, a cold front will move off the NE
Florida coast early Mon, reach from 31N75W to near Jupiter Inlet,
Florida by early Tue, and then stall and dissipate from Bermuda to
the Upper Florida Keys by early Wed. Looking ahead, fresh N winds
and building seas may follow another front reaching along 30N
east of 75W by late Thu night.

and Tropical North Atlantic from 07N to 19N between 55W and 64W
and the Southwest North Atlantic including the Bahamas
This is the last Marine Weather Discussion issued by the National
Hurricane Center. For marine information, please see the Tropical
Weather Discussion at: hurricanes.gov.
...GULF OF MEXICO...
High pressure along the middle Atlantic coasts extending SW to
the NE Gulf will remain generally stationary throughout the
week. This will support moderate to fresh E to SE winds over the
basin through Tue. Winds will increase to fresh to strong late
Tue through Fri as low pressure deepens across the Southern
Plains.
...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W...
A ridge NE of the Caribbean Sea will shift eastward and weaken,
diminishing winds and seas modestly through Wed. Trade winds
will increase basin wide Wed night through Fri night as high
pressure builds across the western Atlantic.
...SW N ATLANTIC INCLUDING THE BAHAMAS...
A weakening frontal boundary from 25N65W to the central Bahamas
will drift SE and dissipate through late Tue. Its remnants will
drift N along 23N-24N. The pressure gradient between high
pressure off of Hatteras and the frontal boundary will support
an area of fresh to strong easterly winds N of 23N and W of 68W
with seas to 11 ft E of the Bahamas late Tue through Fri.

The tropical cyclone statistics from the TWS will be found <br />on hurricanes.gov beginning with the 2025 hurricane season. This <br />change will allow for more frequent updates to the statistics and <br />the addition of graphics and links to supporting information that <br />this text only format cannot support.
