0405 UTC Sat May 3 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 0000 UTC surface analysis and satellite imagery through
0255 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough extends from Costa Rica near 09N83W to 07N105W
and to 05N134W. The ITCZ stretches from 05N134W to beyond
04N140W. Scattered moderate convection is observed from 04N to
10N and east of 113W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
An extensive 1030 mb high pressure system near 35N147W extends
southeastward to the Revillagigedo Islands, supporting moderate
to locally fresh NW-N winds in the offshore waters of Baja
California. Seas in these waters are 4-6 ft. Light to gentle
winds and slight to moderate seas are prevalent in the Gulf of
California.
In the remainder of the Mexican offshore waters, including the
Gulf of Tehuantepec, moderate or weaker winds and slight to
moderate seas prevail.
For the forecast, the moderate to locally fresh NW winds will
continue across the Baja waters through Sat morning, ahead of the
approaching cold front. The cold front will move into the Baja
Norte waters Sat evening and reach the central Baja waters Sun,
accompanied by a significant increase in winds and seas across
the Baja offshore waters, and strong to near gale-force westerly
gap winds across the Gulf of California through Mon morning.
Large NW swell will follow the front, with combined seas in
excess of 8 ft reaching the waters off Punta Eugenia by early
Sun, Cabo San Lazaro Mon, and the Revillagigedo Islands by Tue.
The highest seas may reach 16 ft off Guadalupe Island. Relatively
benign marine conditions will persist elsewhere off southern
Mexico through early next week.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Scattered showers and isolated thunderstorms persist along the
monsoon trough and across the nearshore and offshore waters from
Colombia to Nicaragua. Weak high pressure north of the area
supports gentle to locally moderate winds and slight to moderate
seas across the Gulfs of Papagayo and Panama. Mainly moderate
southerly winds and seas of 4-6 ft primarily in SW swell are
found south of 05N.
For the forecast, gentle to moderate breezes will persist across
the waters off Central America, Colombia and Ecuador through
the middle of next week, with moderate SW swell.
...REMAINDER OF THE AREA....
A strong cold front extends from 30N135W to 28N140W. Moderate to
fresh NE winds and moderate seas are occurring behind the frontal
boundary. A broad subtropical ridge centered northwest of the
discussion waters supports moderate to locally fresh easterly
winds and seas of 6-8 ft north of the ITCZ and west of 110W.
Elsewhere, moderate or weaker winds and moderate seas prevail.
For the forecast, the aforementioned cold front will continue to
move across the waters north of 20N through late Sat, and reach from
central Baja California to 23N140W by Sun evening. Strong high
pressure building behind the front will promote fresh to locally
strong N to NE winds and building seas to 16 ft behind the front
through the weekend, with strongest winds and highest seas
occurring east of 130W.
