Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Tue Sep 8 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 0600 UTC surface analysis and satellite imagery through
0920 UTC.

...SPECIAL FEATURES...

Tropical Storm Marie is centered near 25.5N 126.6W at 08/0900
UTC, moving west-northwest at 7 kt. Estimated minimum central
pressure is 996 mb. Maximum sustained wind speed is 40 kt with
gusts to 50 kt. Peak seas are near 20 ft. Latest satellite
imagery continue to show a sheared Marie, with its center exposed
to the northwest of widely scattered moderate convection in the
SE quadrant from 18N to 26N between 122W and 126W. Marie is
forecast to move west-northwest over the next few days, and is
forecast to become a post-tropical remnant low later today or
Wed. Swells generated by Marie will continue to affect portions
of the coast of the Baja California Peninsula and southern
California for the next couple of days. These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.

Hurricane Center at website -

...TROPICAL WAVES...

A tropical wave has its axis along 90W north of 04N. It is
moving westward at 10 to 15 kt. Scattered moderate isolated
strong convection is from 02N to 16N between 88W and 103W.

A tropical wave has its axis along 112W from 04N to 18N. It is
moving westward at about 10 kt. Scattered moderate isolated
strong convection is from 07N to 20N between 100W and 118W.

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

The monsoon trough axis extends from 09N84W to 11N112W to
09N129W and to beyond 10N140W. Scattered moderate convection is
from 00N to 15N west of 120W.

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

A weak pressure gradient across the region due to the presence of
Tropical Storm Marie to the west of the Baja California Peninsula
is supporting mainly gentle to moderate NW winds off Baja, and
light to gentle winds along with slight seas in the Gulf of
California. A broad area of low pressure located several hundred
miles southwest of southwestern Mexico with potential to develop
into a tropical cyclone later in the week is supporting moderate
to fresh winds off Jalisco and south of the Revillagigedo
Islands. Otherwise, moderate to fresh winds are pulsing in
Tehuantepec.

For the forecast, showers and thunderstorms associated with the
broad area of low pressure located several hundred miles
southwest of southwestern Mexico have the potential for gradual
development, and a tropical depression could form later this week
while the system moves generally west-northwestward at 10 to 15
kt. Regardless of development, this system will bring at least
moderate to strong winds to the offshore waters of Jalisco and
the Revillagigedo Islands today through Wed night. Otherwise,
fresh to locally strong winds will pulse in the Gulf of
Tehuantepec through Fri.

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

Fresh to strong northeast to east winds are in the Gulf of
Papagayo region. Seas there are 5 to 7 ft in southwest swell.
Gentle to moderate S to SE winds are across the offshores between
Ecuador and the Galapagos Islands along with slight to moderate
seas. Otherwise, moderate or weaker winds along with slight to
moderate seas are elsewhere.

For the forecast, high pressure north of the area will support
fresh to strong easterly winds, and moderate to rough seas across
the Gulf of Papagayo region through Sat. Building high pressure
north of the area will also lead to near-gale force winds Wed and
Wed night. Meanwhile, moderate to fresh southerly winds are
expected over the waters between Ecuador and the Galapagos today
through Wed night, then diminishing some afterward. Moderate or
lighter winds are expected elsewhere.

...REMAINDER OF THE AREA...

Please see the Special Features section for information
on Tropical Storm Marie.

Tropical Storm Marie is near 25.5N 126.6W at 2 AM PDT, and is
moving west-northwest at 7 kt. Maximum sustained winds are 40 kt
with gusts to 50 kt, and the minimum central pressure is 996 mb.
Outside from marine impacts attributed to Marie over the
northeast portion of the region, moderate or weaker winds along
with seas of 5 to 7 ft are over the remainder of the tropical
eastern Pacific.

For the forecast, Marie will move to 26.3N 127.5W this
afternoon, weaken to a remnant low near 27.9N 128.6W Wed morning,
29.8N 129.9W Wed afternoon, 32.1N 131.4W Thu morning, and
dissipate Thu afternoon.

Long-period northwest to north swell is merging with cross-
equatorial Southern Hemispheric swell south of about 00N and
between 104W and 122W. This swell area is forecast to expand
eastward through Wed as the primary swell direction becomes
northwest to north. Seas from this swell are expected to be 7 to
9 ft. To the east, an area of disorganized showers and
thunderstorms associated with a tropical wave located several
hundred nautical miles south-southwest of southwestern Mexico
have the potential for gradual development, and a tropical
depression could form later this week while the system generally
west-northwestward.
