Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1815 UTC Wed Jun 17 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.

...SPECIAL FEATURES...

Newly formed Tropical Storm Arthur is centered near 28.6N 95.8W at 
17/1500 UTC or 27 nm ENE of Port Oconnor Texas, moving NE at 8 kt. 
Estimated minimum central pressure is 1001 mb. Maximum sustained 
wind speed is 35 kt with gusts to 45 kt. Numerous moderate to
scattered strong thunderstorms are active around 150 nm to the 
southeast of Arthur, and scattered showers and thunderstorms are 
active elsewhere within 90 nm to 270 nm in the southeast 
semicircle of Arthur. Rough seas are noted within 180 nm in the 
southeast quadrant of Arthur, with maximum seas to 11 ft. The 
strongest winds and rougher seas are expected to remain offshore 
to the southeast of Arthur as it moves along the Texas coast 
through the afternoon. Winds and seas will diminish over the 
northwest Gulf starting this evening as the center of Arthur move 
inland near the Sabine Pass. However, strong onshore flow and poor
marine conditions will persist off southwest Louisiana into the 
overnight hours.

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 
Arthur NHC Forecast/Advisory and Public Advisory at 
www.hurricanes.gov for more details.

...TROPICAL WAVES...

A new tropical wave is along the west coast of Africa, along 16W,
south of 17N, moving west around 10 kt. Scattered moderate to
strong convection is noted from 05N to 08N between 14W and 18W.

An eastern Atlantic tropical wave is along 35W, south of 17N, 
moving westward at 15 kt. No significant convection is evident
near this tropical wave at this time.

An Atlantic tropical wave is along 58W, south of 17N, moving 
westward at 15-20 kt. No significant convection is evident
near this tropical wave at this time.

A central Caribbean tropical wave is along 75W, south of 17N, 
moving westward at 15-20 kt. Scattered moderate convection is
active from 15N to 17N between 75W and 78W.

...MONSOON TROUGH/ITCZ...

The monsoon trough remains over land at this time. Segments of the
ITCZ extend from 06N19W to 07N33W, and from 06N37W to 03N51W.
Scattered moderate convection is active from 03N to 06N between
20W and 30W, and from 05N to 07N between 37W and 42W.

...GULF OF AMERICA...

Please refer to the Special Features section above for details on
newly formed Tropical Storm Arthur along the middle Texas coast.

Outside of the conditions concerning Tropical Storm Arthur
discussed above in the the Special Features section, the remainder
of the Gulf is under the influence of the subtropical ridge that 
extends from the western Atlantic, across Florida into the central
Gulf. This pattern is supporting fresh to strong SE to S winds
across the central Gulf, where seas are estimated to be 5-7 ft.
Gentle to moderate SE to S winds persist elsewhere with 2-4 ft
seas. 

For the forecast, Arthur will weaken to a tropical depression near 30.0N 94.2W 
this evening, become a remnant low and move to 31.9N 91.6W Thu morning,
and dissipate Thu evening. Swells generated by Arthur are likely 
to cause life-threatening surf and rip current conditions along 
the northwestern Gulf Coast for the next couple of days. 
Otherwise, a tightening pressure gradient will develop over the 
basin and sustain fresh to strong southerly winds over the western
and central Gulf late today through Thu night, and moderate to 
fresh winds over the eastern Gulf. Winds and seas will begin to 
diminish late Fri through the weekend as weak high pressure 
settles over the eastern Gulf. 

...CARIBBEAN SEA...

The broad subtropical ridge over the western Atlantic is
maintaining fresh to strong easterly trade winds and moderate to 
rough seas in the central Caribbean. Fresh SE winds and 5-6 ft
seas are noted over the Gulf of Honduras. Moderate E to SE winds
and 4-5 ft seas are noted elsewhere. Trade wind convergence is
supporting scattered showers and thunderstorms over the far 
southwest Caribbean, off Panama, Costa Rica, and southeast 
Nicaragua. 

For the forecast, the western Atlantic ridge will remain in place north
of the area along 27N-28N through early Sat before weakening Sat
night through Mon, as a frontal system moves slowly offshore of
the SE U.S. coast. The pressure gradient south of the ridge will
sustain fresh to strong trade winds and moderate to rough seas
in the south-central Caribbean through the forecast period, with 
highest winds and seas expected off the coast of Colombia. Pulsing
winds at fresh to strong speeds and moderate to rough seas are 
expected in the Gulf of Honduras nightly through Sat, pulsing 
briefly to near gale-force tonight and Thu night. Moderate to 
fresh E to SE winds are expected elsewhere across the northwestern
Caribbean through Sun. Active showers and thunderstorms are 
expected across SW portions Wed through Fri as an upper-level 
trough digs into the area. 

...ATLANTIC OCEAN...

The Bermuda-Azores subtropical ridge is the dominant feature of 
interest across the tropical Atlantic, and is interrupted only by
a frontal trough extending into the region from the western Azores
to 22N48W. This pattern is supporting moderate southern flow and
4-5 ft seas over west of 70W, gentle breezes and 3-4 ft seas north
of 22N along the ridge axis, and moderate to fresh trade winds and
5-6 ft seas south of 22N.

For the forecast west of 55W, the Atlantic subtropical ridge will dominate
the forecast area through Fri, then begin to weaken Fri night 
through the weekend as a weak cold front moves slowly offshore of 
the SE U.S coast. The related pressure gradient will maintain 
moderate to locally fresh trade winds south of 22N through Fri, 
diminishing slightly Fri night through Sat. Moderate to locally 
fresh SW winds offshore of northeast Florida to near 72W will 
expand eastward to near 65W through tonight, as a weak frontal 
system moves across the southeastern U.S. The front is expected to
move slowly offshore early Sat and stall offshore northeast 
Florida by Sun. Expect fresh to strong winds each afternoon 
through late evening across Atlantic waters near Puerto Rico and 
Hispaniola.

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Wed Jun 17 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 1800 UTC surface analysis and satellite imagery through
1900 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is entering the basin near 78W from
just offshore western Colombia northward to eastern Panama and
into the Caribbean Sea, moving westward around 20 kt. Any nearby
convection is described with the monsoon trough below.

The axis of a tropical wave is near 91.5W extending from 02N 
northward near the Galapagos Islands to across portions of
Guatemala, moving westward at around 20 kt. Any nearby 
convection is described with the monsoon trough below.

The axis of a tropical wave is analyzed near 111W extending from
03N to 16N. Any nearby convection is described with the monsoon 
trough below.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough extends from the SW Caribbean Sea to across
the border of Costa Rica and Panama to the Pacific near 08.8N84W
to 14.5N93.5W near the Gulf of Tehuantepec. The ITCZ extends 
from 14N101W to 13N109W, then resumes west of a tropical wave
from 12N111W to 08N127W to 09N139W. Scattered moderate isolated
strong convection is from 01N to 09N between 77W and 88W, and
from 01N to 06.5N between 136W and 140W. Isolated to widely 
scattered moderate convection is noted from 09N to 13N between
89W and 98W, from 11N to 15N between 102W and 109W, from 04N to
07N between 106W and 111W, and within 180 nm either side of the
ITCZ between 112W and 124W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface trough extends from the northern Gulf of California  
into Baja California Sur to near the Revillagigedo Islands. The 
pressure gradient between the trough and surface ridging to the 
west is supporting mainly moderate NW-N winds offshore Baja
California to the north of Cabo San Lazaro, and moderate to fresh
SE-S winds in the Gulf of California, locally strong N of 29N. A
weak pressure gradient across the remainder discussion waters is
supporting light to gentle winds. Moderate seas dominate the
offshore waters with heights of 5-7 ft in S-SW Swell. In the Gulf
of California, seas are mainly 2-4 ft.

For the forecast, gentle to moderate winds will prevail across 
the waters of Baja California, pulsing to locally fresh speeds at
night. Gentle to occasionally moderate winds are expected inside
the Gulf of California and near the tip of Baja California Sur, 
reaching to locally fresh to strong speeds tonight into early 
Thu. Light to gentle winds will prevail over the waters between 
Cabo Corrientes and Tehunatepec. Moderate seas in mainly 
southerly swell will prevail through the next several days, 
slight in the Gulf of California. 

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

Mainly light to gentle winds under a weak pressure gradient 
prevail across the offshore waters along with moderate seas in 
S-SW swell. Otherwise, scattered heavy showers and tstms are 
across the offshore waters of Colombia and Panama ahead of a
tropical wave currently analyzed in the Caribbean Sea. Winds and
seas may be higher in and near these areas of deep convection.
Some scattered showers and isolated thunderstorms are also
occurring offshore El Salvador and Guatemala near another
tropical wave.

For the forecast, gentle to occasionally moderate S to SE winds 
and moderate seas will prevail across the offshore waters between
Ecuador and the Galapagos Islands through at least Sun night. 
Moderate winds will pulse to fresh in diurnal offshore flow in 
the immediate Gulf of Papagayo. Light to gentle winds and slight
to moderate seas in SW swell are forecast elsewhere through at
least the next several days.

...REMAINDER OF THE AREA...

A surface trough, remnant of Invest EP93, is near 140W. The most
concentrated associated convection has pushed W of 140W while
moderate to fresh winds linger from 11N to 18N between 136W and
140W. Elsewhere, moderate or weaker winds and moderate seas 
prevail, with a frontal trough along 28N/29W which is helping to
weaken the pressure gradient with ridging along 24N/25N. Sporadic
convection, some associated with passing tropical waves, is near
the monsoon trough and ITCZ as described above.

For the forecast, the remnants of former Invest EP93, will move
farther west of 140W later tonight. Elsewhere, moderate or 
weaker winds, and moderate seas will prevail, except seas 
building to rough south of and near the Equator and east of 120W 
in new southerly swells through the end of the week. Winds may 
pulse to fresh in the west-central waters at times. Looking 
ahead, yet another set of southerly swell may build seas to rough
over the same area during the upcoming weekend, then decaying
early next week.
