Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Thu Jun 25 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
1930 UTC.
...TROPICAL WAVES...
The axis of a tropical wave is near 107W, south of 17N, moving
westward at around 10 kt. Numerous moderate and scattered strong
convection is noted from 10N-18N between 98W-108W.
The axis of a tropical wave is near 122W, south of 21N, moving
westward at around 10 to 15 kt. No significant deep convection is
occurring with this system this morning.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough extends from coastal Costa Rica at 09N84W to
07N97W to 11N119W to 09N124W. The ITCZ extends from 10N124W to
beyond 08N140W. Numerous moderate and scattered strong
convection is noted from 10N-18N between 98W-108W. Scattered
moderate and isolated strong convection is also noted from
03N-06N between 103W-109W, from 02N-07N between 91W-96W, and
north of 03N between 81W-87W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A Tehuantepec gap wind event is producing fresh to strong N to
NE winds with seas 7-8 ft this afternoon. A surface ridge
extends from 27N120W southeastward to 20N110W. Winds elsewhere
across the offshore waters are moderate or weaker. Seas on the
Pacific waters are 5-6 ft in S to SW swell and are 1-3 ft over
the Gulf of California waters.
For the forecast, low pressure over the deep tropics will
continue inducing fresh to strong N to NE gap winds across the
Gulf of Tehuantepec through tomorrow night. Elsewhere, winds and
seas across the Mexican offshore waters should be quiescent
through early next week. Looking ahead, large NW swell may move
into the waters off Baja California Norte starting Sun night.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
A gap wind event is forcing fresh to strong NE winds across the
Gulf of Papagayo region this afternoon with seas 7-9 ft.
Elsewhere winds are moderate or weaker. Seas are 7-9 ft in S
swell over the equatorial waters and 5-6 ft in SW swell over the
remainder of the offshore waters.
For the forecast, the pressure difference between high pressure
north of the area and the monsoon trough farther south is
supporting a Gulf of Papagayo region gap wind event. Fresh to
strong NE to E winds should last through early next week.
Elsewhere, winds should remain quiescent. Large S swell moving
into the equatorial waters will continue through Sat night.
...REMAINDER OF THE AREA...
A 1008 mb low is centered near 18N122W. Winds within 180 NM in
the N semicircle are fresh to strong with seas 6-8 ft. A surface
ridge extends from a 1032 mb high at 37N154W southeastward to
30N128W to 27N120W to 20N110W. The moderate pressure gradient
between the ridge and lower pressure over the monsoon trough/ITCZ
is forcing moderate to fresh NE trades between 10N and the
ridge. Elsewhere, winds across the open Pacific are moderate or
weaker. Seas are 5-8 ft in mixed SW and N swell.
For the forecast, the low is no longer a candidate for tropical
development and should open up into a trough tomorrow. The
tropical wave near 107W is forecast to encounter more favorable
conditions for development over the weekend across the central
portion of the East Pacific basin. A tropical depression is
likely to form by the early to middle part of next week while the
wave moves westward to west-northwestward at 10 to 15 kt over
the west-central eastern Pacific. Outside of this system, little
change in winds are expected for the next several days. A large
SE swell should reach our southern border tonight and reach up to
01N with at least 8 ft seas for the next several days.
