Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 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 0600 UTC surface analysis and satellite imagery through
0830 UTC.

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

A surface trough extends westward from near the coastal border 
of Panama and Colombia to 08N102W. An ITCZ continues from 08N102W
to 07N120W to beyond 08N140W. Numerous moderate to scattered 
strong convection is noted from 04N to 11N between 130W and 
138W. Scattered moderate to isolated strong convection is
occurring from 03N to 09N between 112W and 127W.

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

A 1029 mb high near 34N139W is supporting moderate to fresh NW to
N winds with seas of 6 to 8 ft west of Baja California, and near
the Revillagigedo Islands. In the Gulf of California, moderate 
to fresh NW to N winds with 3 to 5 ft seas are evident at the 
central and southern Gulf, while gentle winds and 1 to 3 ft seas
exist at the northern Gulf. Mainly gentle winds with seas at 2 
to 4 ft prevail for the offshore waters of central and southern
Mexico.

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. Moderate to fresh 
NW winds over waters on both sides of the Baja California 
peninsula will become gentle to moderate by this evening. 
Afterward, fresh to strong W to NW winds with rough seas are 
expected 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...

Refer to the Intertropical Convergence Zone/Monsoon Trough
section for convection. Moderate to fresh easterly winds and seas
of 4 to 5 ft are evident off the Papagayo region. Mainly gentle
winds with 2 to 4 ft seas are noted for the remaining central
America offshore waters. Gentle to moderate S to SW winds and
seas at 4 to 5 ft prevail near Ecuador and the Galapagos Islands.

For the forecast, convergent winds near a surface trough are 
going to maintain heavy showers with strong thunderstorms and 
gusty winds in the offshore waters of Costa Rica, Panama and 
Colombia through at least Sat night. Fresh NE to E winds will 
linger in the Papagayo region until late this 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 broad surface ridge extends southeastward from a 1029 mb high
near 34N139W to just south of the Revillagigedo Islands. It is
sustaining moderate to fresh NE to ENE trade winds and seas of 6
to 9 ft north of the ITCZ and west of 130W. East of 130W and 
north of the ITCZ, gentle to moderate N to NE winds and 6 to 7 ft
seas exist. South of the ITCZ, mainly gentle SE to S winds with 
seas of 4 to 6 ft prevail.

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 to 20N and west of 130W through the weekend.
