Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Fri May 1 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 0000 UTC surface analysis and satellite imagery through
0330 UTC.

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

A surface trough axis extends westward from near the coastal
border of Panama and Colombia to 09N86W to 06N99W. An ITCZ
extends from 06N99W to 10N120W to beyond 06N140W. Numerous
moderate to isolated strong convection is noted from 04N to 10N
between 112W and 134W. Scattered moderate and isolated strong
convection is noted from 03N to 08N between 83W and 111W.

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

A surface ridge extends southeastward from 30N128W to 20N115W to
15N108W. Winds are NW moderate to fresh west of the Baja
California peninsula. Elsewhere, winds are moderate or weaker.
Seas are 5-7 ft in NW swell west of the Baja California
peninsula, 3-5 ft in mixed swell south of S Mexico, and 1-4 ft
over the Gulf of California.

For the forecast, beginning Sat night, a Gulf of Tehuantepec gap
wind event will occur. These winds could reach Gale-force Sun
and Sun night before quickly diminish by Mon. Fresh to locally
strong NW winds over waters on both sides of the Baja California
peninsula will linger through Fri morning, then occur again at
the northern Gulf of California Sun and Sun night.

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

Winds are moderate or weaker with seas 4-6 ft in S swell over
forecast waters. Scattered moderate and isolated strong convection
is noted from 03N-06N east of 100W.

For the forecast, fresh NE to E winds will pulse in the Papagayo
region through early Fri morning. Residual southerly swell is
going to keep moderate seas near the Galapagos Islands through
Sat. Elsewhere, quiescent conditions should prevail through
early next week.

...REMAINDER OF THE AREA...

A surface ridge extends southeastward from 30N128W to 20N115W to
15N108W. The pressure gradient between the ridge and lower
pressure over the ITCZ is forcing moderate to fresh NE trades
north of 09N. Elsewhere winds are moderate or weaker. Seas are
8-9 ft from 18N-22N west of 134W in mixed N swell and wind
waves. Elsewhere seas are 5-7 ft in mixed swell.

A weakening pressure gradient will gradually diminish the trade
wind strength and extent through early next week. A N to NW
swell will continue to combine with wind waves to cause 8-10 ft
seas from 10N-20N west of 130W through the weekend.
