Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Thu Apr 25 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
0600 UTC.

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

An equatorial trough curves northwestward from the border of
Colombia and Panama near 07N79W to 05N81W to 08.5N92.5W. The 
ITCZ extends from 08.5N92.5W to 06N115W to 04N130W to 05N140W.
Scattered moderate isolated strong convection is noted from 06N 
to 08N between 97W and 101W, from 04N to 10N between 108W and 
130W, and from 02N to 06N between 137W and 140W. Scattered 
moderate convection is noted from 02N to 08N between 130W and 
135W.

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

A surface ridge extends southeastward roughly along the outer
offshore waters boundary. A surface trough is located just to the
W of the Baja California Norte waters W of 110W. The pressure 
gradient over the northern waters is supporting fresh to strong
SW winds in the northern Gulf of California, with similar winds
our of the NW near Punta Eugenia per recent ASCAT scatterometer
data. Moderate to fresh NW-N winds are elsewhere W of Baja
California. Mainly gentle to moderate winds prevail across the 
remainder of the offshore waters. Seas are 4 to 6 ft in merging 
SW and NW swell across the open waters, and 1 to 3 ft in the Gulf
of California, except 4 to 6 ft in the northern Gulf.

For the forecast, SW fresh to strong winds, locally near-gale 
force, will pulse in the northern Gulf of California through the 
morning, and again Fri evening through early Sat morning. 
Starting today, high pressure across the East Pacific is going 
to strenghten. This will cause gentle to moderate northerly 
winds west of Baja California and near the Revillagigedo Islands 
to become fresh to locally strong along with building seas by 
Fri. The pressure gradient across the waters will weaken by the 
end of the weekend into early next week resulting in fairly 
tranquil conditions.

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

Moderate to fresh winds are noted in the Gulf of Panama with
fresh to strong winds offshore the Papagayo region. Winds are
light to gentle elsewhere N of 10N, and gentle to moderate
elsewhere S of 10N. Seas are 4 to 6 ft in S to SW swell across 
the offshore waters.

For the forecast, fresh to strong NE winds near the Gulf of 
Papagayo will pulse through Fri morning, then moderate to fresh 
through Sat morning. Moderate to fresh N winds will pulse in the 
Gulf of Panama today. Little change in seas is expected during 
the next several days.

...REMAINDER OF THE AREA...

A frontal trough is over the northern waters from 30N121W to 
26N130W. Otherwise, broad ridging dominates the waters N of the 
ITCZ. Moderate to fresh trades and 6 to 9 ft seas are from 07N 
to 23N and W of 110W, locally strong from 08N to 22N and W of
128W. Mainly gentle to moderate winds prevail across the 
remainder of the waters, along with seas of 5 to 7 ft, primarily 
in SW swell S of 10N and primarily in NW swell N of 10N.

For the forecast, the moderate to fresh trade winds will
occasionally pulse to strong, along with continuing 6 to 9 ft 
seas under the ridge. Meanwhile, the trough in the northern 
waters will dissipate through tonight while shifting E. Moderate
to fresh N to NE winds and seas at 7 to 10 ft are expected north
of 20N and E of 125W by Fri. Little change is forecast across 
the remainder of the waters into early next week.
