Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Tue Apr 2 2024

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
0710 UTC.

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

An equatorial trough extends from the coast of Colombia near
05N77W to 05N85W. The ITCZ continues from 05N85W to 06N115W to
01N140W. Scattered moderate strong convection is noted from 02N
to 08N between 130W and 132W.

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

High pressure dominates the offshore waters. Moderate winds are
N of 18N, with light to gentle winds S of 18N, except moderate 
nearshore of Oaxaca. Old NW swell with seas of 7 to 9 ft is 
decaying W of 110W, with 4 to 7 ft seas elsewhere.

For the forecast, southward building ridging will lead to fresh 
to strong winds pulsing near Cabo Corrientes tonight through Wed.
Similar winds are forecast in the central and southern Gulf of 
California tonight into Wed night. Fresh to near gale-force SW 
winds may develop in the northern Gulf of California Thu night 
into early Sat. Also, near gale force northerly winds may develop
in the Gulf of Tehuantepec Wed evening through Fri. Looking 
ahead, new large NW swell may impact the Baja California waters 
by the end of the week, with fresh to strong NW-N winds near 
shore from Cabo San Lazaro northward.

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

Fresh gap winds are flowing across the gulfs of Papagayo and 
Panama. Elsewhere, mainly gentle winds prevail. Seas are 3 to 5 
ft.

For the forecast, moderate to fresh gap winds in the gulfs of 
Papagayo and Panama will diminish later today, then return in 
Papagayo Fri night through Sat night. Otherwise, light to gentle 
winds and 3 to 5 ft seas will prevail, building slightly offshore
Ecuador to the Galapagos Islands this weekend.

...REMAINDER OF THE AREA...

Ridging dominates the waters N of the ITCZ. The ridging combined
with lower pressures near the ITCZ is supporting a belt of fresh
to strong trades from 10N to 20N to the W of 115W as sampled by
recent ASCAT scatterometer data. Seas in this area are 9 to 11 ft
as confirmed by recent altimeter data. Moderate to fresh trades
prevail elsewhere W of 110W along with 6 to 8 ft seas. Gentle
winds and 4 to 6 ft seas prevail E of 110W.

For the forecast, a belt of fresh to strong trades just N of the
ITCZ and W of 120W will persist through the week, diminishing
somewhat this weekend. The fresh to strong trades will support 7
to 11 ft seas. A decaying cold front or remnant trough may move 
into the NW waters by mid-week with fresh to strong winds behind
it. A set of NW swell will arrive with the boundary, building 
seas to 8 to 12 ft N of 20N and W of 130W through the end of the 
week. Looking ahead, additional northerly swell may drop S of 30N
by the end of the week into the weekend, with the potential to 
build seas to greater than 12 ft N of 26N and E of 130W.
