Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Fri Jul 11 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.

...TROPICAL WAVES...

The axis of a tropical wave is near 90W north of 08N, moving
westward around 10 kt. Numerous moderate to strong convection is
noted north of 12N and east of 93W.

The axis of a tropical wave is near 108W north of 08N, moving
westward around 5 to 10 kt. Widely scattered moderate convection
is noted from 13N to 16N between 104W and 109W.

The axis of a tropical wave is near 119W from 07N to 15N, moving
westward around 10 kt. Scattered moderate convection is noted
from 10N to 14N between 119W and 121W.

The axis of a tropical wave is near 129W from 05N to 14N, moving
westward around 5 kt. Scattered moderate convection is noted
from 08N to 10N between 129W and 131W.

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

The monsoon trough extends from coastal Panama near 10N85W to
09N130W. The ITCZ continues from 09N130W to beyond 08N140W.
Numerous moderate to strong convection is occurring north of 05N
and east of 89W. Scattered moderate to isolated strong convection
is noted from 09N to 12N between 95W and 99W, and from 07N to
12N between 121W and 126W.

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

A surface trough has been analyzed over the northern Gulf of
California to 27N111W, and recent scatterometer satellite data
show and fresh to locally strong S to SE winds and seas of 2 to 5
ft through the Gulf. Elsewhere, ridging extends across the
waters offshore of Baja California, where moderate NW winds and
seas of 4 to 7 ft in NW swell prevail. Otherwise, gentle to
locally moderate winds and seas of 3 to 6 ft in S swell are noted
offshore of southern Mexico.

For the forecast, fresh to strong S to SE winds will occur
across the central and northern Gulf of California into early Sat
as troughing prevails over the region. Moderate to locally fresh
winds will then pulse in this area into early next week.
Elsewhere, moderate to occasionally fresh NW are expected over
the Baja California waters into early Sat as high pressure
prevails to the northwest. Winds will diminish on Sat as the high
weakens. Looking ahead, moderate to fresh N gap winds will
develop in the Gulf of Tehuantepec early next week.

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

Moderate to fresh E to NE winds are occurring in the Gulf of
Papagayo as low pressure prevails over northern Colombia. Gentle
to locally moderate winds are noted elsewhere north of the
monsoon trough. To the south, moderate S to SW winds are observed
via scatterometer data. A long period S to SW swell is moving
through the regional waters, promoting seas of 4 to 7 ft, with
locally rough seas to 8 ft occurring south of the Galapagos
Islands, as captured by recent altimeter satellite data.

For the forecast, fresh to locally strong E to NE winds will
pulse in the Gulf of Papagayo through Sat morning as low pressure
dominates the south-central Caribbean. Winds will diminish for
the rest of the weekend before winds restrengthen early next
week. Elsewhere, moderate to occasionally fresh S to SW winds
will occur south of the monsoon trough into next week. A long
period S to SW swell will promote rough seas over the equatorial
waters today, with seas subsiding this weekend.

...REMAINDER OF THE AREA...

A 1033 mb high, centered north of the area near 40N141W, extends
ridging through the eastern Pacific waters north of the monsoon
trough and ITCZ. Scatterometer data show moderate to locally
fresh N to NE winds occurring in this region, and accompanying
seas of 4 to 7 ft. Elsewhere, a long period mixed SW and SE swell
is moving through the equatorial waters, promoting rough seas of
8 to 10 ft south of 05N, as displayed on altimeter data.
Moderate to locally fresh SE winds are noted in this area.

For the forecast, moderate to fresh N to NE winds and moderate
seas are expected north of the monsoon trough and ITCZ into early
next week as ridging prevails over the eastern Pacific.
Elsewhere, rough seas over the equatorial waters will slowly
subside today, before another modest swell may produce rough seas
south of the equator Sun into early next week. Moderate to fresh
SE winds will occur south of the monsoon trough and ITCZ through
the middle of next week.
