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
0400 UTC.
...SPECIAL FEATURES...
Fay has strengthened to a Tropical Storm again, and is centered
near 26.0N 45.9W at 29/0300 UTC, or 1200 nm W-SW of the Azores,
moving SW at 9 kt. Estimated minimum central pressure is 1008 mb.
Maximum sustained wind speed is 35 kt with gusts to 45 kt. Seas to
10 ft are within 75 nm in the NW semicircle. Northwesterly
vertical wind shear continues to force convection to the south
and southeast of the center of Tropical Storm Fay. Numerous
moderate to strong convection is occurring from 23N to 26N between
43W and 46W. A general SW to W-SW motion is anticipated over the
next several days. Some minor fluctuations in intensity may occur
through early Wed as convection pulses, before Fay weakens to a
post tropical remnant low Wed morning.
Please read the latest HIGH SEAS FORECAST issued by the National
Hurricane Center at website
- https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml and the latest
Fay NHC Forecast/Advisory and Public Advisory at
www.hurricanes.gov for more details.
...TROPICAL WAVES...
A Caribbean tropical wave is analyzed along 75W, south of 18N
into northwestern Colombia, moving west at 10 kt. Isolated
clusters of moderate convection are found from 14N to 16N between
74W and 76.5W, while scattered moderate convection is found along
the NE coast of Colombia between 73W and 74W.
...MONSOON TROUGH/ITCZ...
The monsoon trough exits Africa along the coast of Mauritania near
21N17W and extends to 1011 mb low pres near 21N25.5W then to
07N39W. The ITCZ extends from 06.5N40W to 09N51W to the coast of
Venezuela near 09N61W. Scattered moderate isolated strong convection
is noted from 10N to 13.5N E of 21N to the African coast, and
within 120 nm NW and 210 nm SE of the monsoon trough between 26W
and 40W. Widely scattered moderate convection is within 75 nm N of
the ITCZ between 45W and 54W and between 60W and 63W.
...GULF OF AMERICA...
Scattered moderate isolated strong convection extends form the
entire Yucatan Peninsula and southeastern Mexico towards the north-
northeast and across the southeastern Gulf waters to the offshore
waters of western Florida near Cedar Key. This activity is
occurring to the east and southeast of an upper level trough
extending from the northeast Gulf through the Bay of
Campeche. Mostly fair skies prevail elsewhere. At the surface, a
weak stationary lingers over the northern coastal waters from
SE Louisiana to near Apalachicola, Florida. Light to gentle winds
south to southeast winds prevail across most of the basin,
yielding slight seas. Moderate to fresh easterly winds across the
northern coastal waters of the Yucatan are producing seas 3 ft and
locally higher.
For the forecast, the weak stationary front over the NE Gulf will
dissipate tonight. High pressure north of the dissipated front
will support gentle to moderate E to SE winds across the Gulf
through Tue. Expect moderate to fresh winds and building seas
over mostly the western Gulf by Tue night, as the high pressure
shifts eastward ahead of a cold front moving through the Southern
Plains. Looking ahead, winds and seas will diminish late in the
week as the front stalls across eastern Texas Fri and Sat.
...CARIBBEAN SEA...
Deep layer troughing extending from the NE Gulf of America
southward across the Yucatan Peninsula and extreme western
Caribbean is supporting scattered clusters of moderate isolated
strong convection across the NW basin, N of 13N and W of 77W, and
extending northeastward into the Bahamas. Weak high pressure
across the western Atlantic has drifted southward to near 27N59W,
and tightened the pressure gradient modestly in the past 24
hours. This is leading to moderate trades across most of the basin
E of 77W, and fresh to locally strong winds S of 14N near the
coast of NE Colombia. Seas are 5 to 6 ft in these strongest winds
and 3 to 5 ft elsewhere E of 77W. Fresh to locally strong E to SE
winds are also occurring across the Gulf of Honduras S of 18N,
where seas are 4 to 5 ft and building. Mainly gentle yo moderate E
to SE trades previal across the remainder of the basin, except
light and variable SW portions.
For the forecast, weak high pressure is slowly building across the
central Atlantic, to the SE of a trough extending from Sw of
Bermuda to the northern Bahamas. This pattern is supporting a
modest pressure gradient over the region tonight. Expect moderate
to fresh E to SE winds and building seas across the basin by
midweek as high pressure builds north of the area, with rough seas
possible in the Yucatan Channel and far NW Caribbean Thu night
through Fri.
...ATLANTIC OCEAN...
Please see the Special Features section above for information on
Tropical Storm Fay.
Ample low level moisture persists to the S and SE of a surface
trough extending from SW of Bermuda to the NW Bahamas. Scattered
moderate isolated strong convection is occurring within 210 nm S
and SE of this trough, where gentle to moderate S to SE winds
prevail at the surface. Similar S to SE winds prevail to the N of
the trough W of 75W. To the S of 22N gentle to moderate easterly
trades prevail W of 60W, except fresh winds along the N coast of
Hispaniola. Seas are generally 4 to 5 ft in northerly swell and 3
ft or less W of 74W. To the E, T.S. Fay is centered near 26.0N
45.9W, and is sandwiched in between two high centers at 28N57W
and 31N44W. This pattern is leading to mainly gentle to locally
moderate NE to E winds S of 22N between 30W and the Lesser
Antilles, with 5 to 7 ft seas. Further east, the 1011 mb remnants
of Gonzalo are near 21N25.5W, and is still producing moderate to
locally fresh cyclonic winds and 5 to 7 ft seas to the N and W of
the center. Elsewhere across the basin, moderate seas dominate.
For the forecast west of 55W, scattered showers and a few
thunderstorms will persist through morning along a trough
reaching from the SW Bermuda adjacent waters to the northern
Bahamas. The trough will dissipate through Tue, allowing high
pressure to build over the western Atlantic. This pattern will
support moderate to fresh E winds and 3-5 ft seas south of 25N by
midweek.

Issued at 500 AM AST Tue Sep 29 2026000 WTNT41 KNHC 290850 TCDAT1 Tropical Storm Fay Discussion Number 37 NWS National Hurricane Center Miami FL AL062026 500 AM AST Tue Sep 29 2026 Proxy-visible satellite imagery shows that the convection around Fay has increasingly become more sheared in the last several hours. Infrared imagery does still show some of the convection has cloud tops near -70 C. In addition, the most recent TAFB Dvorak fix was 2.0/30 KT, and the objective intensity estimates from UW-CIMSS are in the range of 33-43 kt. Therefore, the initial intensity has been held at 35 kt for this advisory. The storm is still moving toward the southwest with an estimated initial motion of 235/11 kt. Fay is expected to keep a general southwestward to west-southwestward motion for the next couple of days as the cyclone is guided by the flow along the southern periphery of a mid-level ridge situated over the central Atlantic. The current NHC track forecast is almost identical to the previous one with just a few minor adjustments based on the HCCA and GDMI forecast aids. With the convection expected to pulsate for the next couple of days, the intensity will also fluctuate as well. However that convection will likely become increasingly separated from the center as the SHIPS guidance indicates increasing vertical wind shear over the couple of days. Based on the global models, Fay will struggle to maintain deep convection as it moves into a more stable air mass and an area of upper-level convergence. The current NHC intensity forecast is based on the HCCA and GDMI forecast guidance and Fay is still expected to become a post-tropical cyclone in a day or so. The global models show the system degenerating into a trough afterwards.

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.
