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 0600 UTC surface analysis and satellite imagery through
1030 UTC.
...TROPICAL WAVES...
An eastern Atlantic tropical wave has its axis along 39W S of
12N, moving westward at 10-15 kt. Scattered showers and
thunderstorms are depicted from 03N to 07N between 35W and 42W.
...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic through the coast of
Africa near 12N16W and continues southwestward to 08N25W, where
it transitions to the ITCZ to 05N36W. The ITCZ resumes W of a
tropical wave near 05N41W to near 06N51W. Scattered moderate
convection is within 60 nm of the ITCZ west of 31W.
...GULF OF AMERICA...
Weak high pressure extends from the western Atlantic to the
eastern Gulf, while a surface trough is analyzed from 22N89W to
18N94W. Scattered moderate convection is depicted along the trough
and south of 20N. The pressure gradient in place is allowing for
light to gentle S to SW winds over the eastern Gulf, and for
mostly gentle to moderate E to SE winds elsewhere, except for
fresh E to SE winds W of the Yucatan Peninsula. Moderate seas
prevail across the basin.
satellite imagery reveals that skies are hazy over the Florida
peninsula and the eastern Gulf due to the presence of the Saharan
Air Layer (SAL).
For the forecast, Atlantic high pressure will extend a ridge into the
eastern Gulf through Sun, then build modestly westward into the
central Gulf through early next week. Moderate to fresh E to NE
winds are expected each afternoon and evening north of the Yucatan
Peninsula and into the eastern Bay of Campeche as a trough
develops daily and moves westward. Expect moderate to fresh SE
winds across the western and south-central Gulf through Mon
between a trough over northern Mexico and Atlantic high pressure.
...CARIBBEAN SEA...
The pressure gradient between a weak high pressure over the
western Atlantic and lower pressures in the southern Caribbean
and in northern S America is allowing for fresh to strong trades
across the south central portion of the basin and the Gulf of
Honduras, while moderate to fresh winds prevail elsewhere. Rough
seas prevail over the central section of the basin, while moderate
seas are noted elsewhere. satellite imagery reveals scattered to
numerous moderate convection S of 13N and west of 75W due to the
eastern end of the E Pacific monsoon trough.
For the forecast, weak high pressure N of the region and centered
NW of Bermuda will shift NE and into the N central Atlantic
through the weekend. The Atlantic ridge will then build SW into
the Bahamas and S Florida late Sat through early next week. This
pattern will lead to fresh to strong trades and moderate to rough
seas across most of the central basin and Gulf of Honduras through
this evening, diminish slightly on Sat, then increase across most
of the basin Sat night into early next week.
...ATLANTIC OCEAN...
A tropical wave is analyzed over the basin. Refer to the section
above for details.
A stationary front extends from near 31N59W to 27N66W. Water
vapor imagery depicts a broad upper-level trough that is over the
central Atlantic N of about 20N and between 53W and 57W. High
pressure prevails elsewhere over the tropical and subtropical
waters as a 1030 mb high center is well N of the area near
38N40W. The pressure gradient in place is supporting moderate to
fresh trades and moderate to rough seas over most of Atlantic S
of 20N and east of 55W. Elsewhere, winds are moderate with
moderate seas.
satellite imagery continues to exhibit an extensive outbreak
of the Saharan Air Layer (SAL) that covers the vast majority of
the eastern Atlantic. A thin swath of this SAL outbreak,
has migrated westward to the northern Caribbean and to some
areas of the western Atlantic, including the Florida peninsula.
For the forecast west of 55W, the stationary front SE of Bermuda
will drift northward and dissipate through tonight. Weak high
pressure NW of the front will shift NE and into the central
Atlantic through Sat. Atlantic high pressure will then build
modestly W-SW into the Bahamas and S Florida Sun through Tue.
Expect fresh to strong winds to pulse each afternoon and evening
offshore of Hispaniola early next week.

Tropical Weather Outlook
Eastern Pacific
ZCZC MIATWOEP ALL TTAA00 KNHC DDHHMM
Tropical Weather Outlook NWS National Hurricane Center Miami FL 500 AM PDT Fri Jun 6 2025
For the eastern and central North Pacific east of 180 longitude:
1. South of Southern Mexico: Showers and thunderstorms have increased a little on the eastern side of a broad trough of low pressure located a couple of hundred miles south of southern Mexico. Environmental conditions appear conducive for additional development, and a short-lived tropical depression is likely to form over the weekend while the system moves generally west-northwestward just off the coast of Mexico. Interests in southern and southwestern Mexico should monitor the progress of this system. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 7 days...high...70 percent.
2. Offshore of Southwestern Mexico: A broad area of low pressure has formed along the western side of the elongated trough south of Mexico. Continued gradual development of this system is expected, and a tropical depression is likely to form over the weekend or early next week while the system moves generally west-northwestward. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 7 days...high...80 percent.

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Fri Jun 6 2025
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 0600 UTC surface analysis and satellite imagery through
0900 UTC.
...SPECIAL FEATURES...
An elongated trough of low pressure is located several hundred
miles south of southern Mexico from 10N to 12N between roughly
100W and 110W. A tropical wave may still be active along 102W,
drifting west at 5 kt. Scattered moderate showers and
thunderstorms are active along the tropical wave from 10N to 14N.
Additional showers and thunderstorms are active within 60 nm of
the coast from El Salvador to the Mexican state of Guerrero.
Recent scatterometer data showed moderate to fresh SE winds along
the coast in the area of showers and thunderstorms. Concurrent
altimeter data showed combined seas of 6 to 8 ft likely in SW
swell south of the elongated trough from 02N to 10N between 90W
and 115W. Environmental conditions appear conducive for
development, and a tropical depression is likely to form over the
weekend while the system moves generally west-northwestward
toward Socorro Island. The expected low has a medium chance of
becoming a tropical cyclone during the next 48 hours. Please
refer to the latest NHC Tropical Weather Outlook at
www.hurricanes.gov for more details.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough axis extends from 08N79W to 11N102W to
08N125W. The ITCZ extends from 08N125W to beyond 06N140W.
Scattered moderate convection is from 10N to 14N between 101W and
104W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Please read the Special Features section for information on
a large area of disorganized showers and thunderstorms located
several hundred miles off the southern coast of Mexico from
which low pressure is expected to form with potential for
tropical cyclone development.
A weak pressure pattern is supporting gentle breezes over most of
the area off Baja California this evening. The except is near the
coast of Baja California Sur where a recent scatterometer
satellite pass depicted moderate to fresh NW winds funneling
mainly off Cabo San Lucas and high pressure farther to the
northwest near 25N120W. Light breezes are noted elsewhere off
southern Mexico and in the Gulf of California. Combined seas are
4 to 6 ft off Baja California primarily in NW swell, and 3 to 5
ft primarily in SW swell off southern Mexico. Slight seas are
noted across the Gulf of California.
For the forecast, the main issue will be the potential for
developing low pressure off southern Mexico described in the
Special Features section. Expect winds to increase and seas to
build across the offshore waters off western Oaxaca and Guerrero
by tonight with building seas. These strong winds and rough seas
will expand westward across the offshore waters toward Cabo
Corrientes through Sun as low pressure deepens farther to the
south off the coast. Mariners should continue to monitor the
latest statements from the National Hurricane Center on the
possible tropical cyclone development. Gentle to moderate winds
and 5 to 7 ft seas are expected elsewhere across Mexican offshore
waters, with slight seas over the Gulf of California.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
A weak pressure gradient remains over the area resulting in
gentle to moderate southerly winds south of the monsoon trough,
and light to gentle winds to the north of it. Cross-equatorial
SW swell is producing moderate seas across the offshore forecast
waters.
For the forecast, gentle to moderate S to SW winds will occur
south of the monsoon trough through this weekend, with mainly
gentle winds expected to the north. Moderate seas in cross-
equatorial swell are likely over the regional waters into this
weekend. Winds are forecast to increase to fresh to strong speeds
offshore Nicaragua Fri night. Abundant tropical moisture will
persist across the region increasing the likelihood of showers
and thunderstorms through at least Sat night.
...REMAINDER OF THE AREA....
A recent scatterometer satellite pass confirmed moderate to
fresh NE winds north of 25N between 1033 mb high pressure well
north of the area near 42N143W and a trough from extending from
southern California to 25N130W. Concurrent altimeter satellite
data showed combined seas of 8 to 10 ft with NE swell in this
area. Seas to 8 ft are likely in an area of moderate to fresh
trade winds from 05N to 10N west of 135W. Outside of the winds
and seas east of 110W described in the Special Features section,
mainly gentle to moderate winds are noted elsewhere with 5 to 7
ft seas in a mix of N and SW swell.
For the forecast, the fresh N to NE winds will persist across
the waters north of 25N and west of 130W through today. The
swell will continue to propagate across the northern forecast
waters through tonight before subsiding into Sat.
