Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1815 UTC Wed Sep 30 2026

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 1200 UTC surface analysis and satellite imagery through 
1700 UTC.

...TROPICAL WAVES...

A western Atlantic tropical wave has its axis along 84W, south of
21N, moving westward at 10 kt. Scattered moderate to isolated
strong convection is observed between 16N and 22N and W of 78W.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic near 12N16W, extends to 
16N30W, and then to 09N41W. The ITCZ extends from 09N41W to the
coastal border of Guyana and Venezuela. Scattered moderate
convection is seen from 09N to 19N between 29W and 40W, as well as
from 07N to 13N between 21W and 30W.

...GULF OF AMERICA...

Deep-layer troughing continues to support showers and 
thunderstorms across the Florida Straits and the far SE Gulf. 
High pressure over the eastern United States supports moderate to 
locally fresh easterly winds and moderate seas over the western 
Gulf waters, while moderate or weaker winds and slight to moderate
seas prevail elsewhere.

For the forecast, showers and thunderstorms will linger in the SE
Gulf through at least this evening. The pressure gradient between
high pressure over the eastern United States and lower pressures 
in Texas and Mexico support moderate to fresh easterly winds over 
the western Gulf waters. These winds will expand eastward across 
the basin by tonight as the pressure gradient tightens. The 
gradient will weaken from west to east by the end of the week into
the weekend as a frontal boundary approaches the western Gulf 
waters, possibly moving into the basin by the end of the weekend 
with weakening winds and subsiding seas ahead of it. Increasing 
winds and building seas are possible behind the very slow moving 
front. 

...CARIBBEAN SEA...

Please refer to the Tropical Waves section above for details on
convection in the NW Caribbean.

The East Pacific monsoon trough extends across the far SW
Caribbean, and is supporting numerous strong convection S of 16N
and W of 78W. High pressure north of the area sustains moderate 
to fresh easterly trade winds across much of the basin, increasing
to strong speeds off northern Colombia and along the northern end
of the tropical wave analyzed along 84W. Seas of 4-8 ft are 
evident across the Caribbean, except for slight seas in the lee of
Cuba and Windward Passage.

For the forecast, a passing tropical wave and divergent flow 
aloft will support scattered showers and isolated thunderstorms W 
of 75W over the next few days. High pressure north of the area 
will support pulsing fresh to strong easterly trade winds in the 
central Caribbean and in the Gulf of Honduras through the 
remainder of the week and into the weekend. Moderate or weaker 
winds will prevail in the rest of the basin. Later, a frontal 
boundary will slide into the Gulf of America and western Atlantic 
this weekend, resulting in a weakening pressure gradient across 
the Caribbean as the ridge retreats. Moderate to locally fresh 
winds will then dominate the basin into early next week.

...ATLANTIC OCEAN...

Deep-layer troughing continues to support scattered moderate
convection across the Bahamas and areas southward toward Cuba. To
the east, convergent surface winds between a 1019 mb high SE of 
Bermuda and the remnants of Fay are supporting scattered moderate 
convection from 21N to 28N between 55W and 63W, as well as near 
the center of Fay's remnants. Outside of convection, gentle to 
moderate E to NE winds and moderate seas prevail across much of 
the Atlantic. Locally fresh winds are seen in showers N of a 
surface trough analyzed just E of the Lesser Antilles.

For the forecast west of 55W, high pressure will persist across 
the region over the remainder of the week and into the weekend 
supporting moderate to locally fresh easterly winds south of 25N. 
Moderate or weaker winds will prevail elsewhere. Meanwhile, the 
remnants of Post-Tropical Cyclone Fay currently east of the 
offshore waters may move west of 55W by tonight. This system will 
continue to weaken and may dissipate late this week. Looking 
ahead, a frontal boundary may reach the waters off NE Florida 
early next week, resulting in an increase in winds and seas behind
the boundary.

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Wed Sep 30 2026

Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.

Based on 1200 UTC surface analysis and satellite imagery through
1500 UTC.

...SPECIAL FEATURES...

Hurricane Rachel is centered near 18.1N 108.0W at 30/1500 UTC,
moving northwest at 8 kt. Estimated minimum central pressure is
978 mb. Maximum sustained wind speed is 75 kt with gusts to 90
kt. Numerous moderate to scattered strong convection extends out
to 360 nm in the southwest semicircle, and 180 nm in the
northeast semicircle. Seas near the center are as high as 32 ft.
On the forecast track, the center of Rachel is expected to move 
away from mainland Mexico and between the southern tip of the Baja
California Peninsula and the Revillagigedo Islands through 
Fri. Swells generated by Rachel will affect the southwestern 
coast of Mexico during the next couple of days and spread 
northward along the coast of west- central Mexico and the Baja 
California Peninsula through the end of the week. These swells 
are likely to cause life- threatening surf and rip current 
conditions. Please consult products from your local weather 
office for more details.

Tropical Depression Nineteen-E is centered near 14.3N 128.4W at
30/1500 UTC, moving east at 9 kt. Estimated minimum central
pressure is 1002 mb. Maximum sustained wind speed is 30 kt with
gusts to 40 kt. Scattered moderate convection is from 13N to 15N
between 128W and 130W. Little change in strength is forecast 
during the next couple of days, and this system is expected to 
degenerate into a post-tropical cyclone by late Thursday.

to the northwest of Clarion Island early Sun. Elsewhere, strong 
winds and rough seas will develop in the Tehuantepec region 
tonight and continue into Fri.

...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, 
AND WITHIN 750 NM OF ECUADOR...

NW swell from Rachel is reaching the waters off Guatemala where
seas are 7 ft. Gentle breezes and slight seas persist off the 
remainder of Central America. Moderate SE to S winds and 5 to 6 
ft seas in a mix of swell are noted off Colombia and Ecuador. 

For the forecast, a light pressure gradient will maintain 
moderate or weaker winds over the offshore waters along with 
mostly moderate seas through the period. 

...REMAINDER OF THE AREA...

Please see the Special Features section above for information on
the recently upgraded Hurricane Rachel and T.D. Nineteen-E.
