Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Thu Apr 6 2023

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 1200 UTC surface analysis and satellite imagery through
1420 UTC.

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

A surface trough extends from 07N77W to 05N115W. The ITCZ 
continues from 05N115W to beyond 02N140W. Scattered moderate 
convection is noted south of 07N and east of 98W.

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

The pressure gradient between a ridge of high pressure west of
the Baja California peninsula and low pressure over Mexico is
supporting moderate to fresh winds over the Gulf of California 
as well as west of the Baja California peninsula. Gentle to 
moderate winds are noted elsewhere. Seas are in the 4-6 ft range 
over the Gulf of California and 6-7 ft west of the Baja 
California peninsula. Seas of 3-6 ft prevail elsewhere. 

For the forecast, the area of low pressure over north-central 
Mexico will weaken and shift east today, which will loosen the
pressure gradient and diminish winds over the Gulf of California
late today. Large swell off the coast of Baja California will 
also subside today. Fresh to strong gap winds and building seas 
are possible over the Gulf of Tehuantepec Sun and Sun night.

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

The pressure gradient between high pressure north of the area 
and the equatorial trough is supporting fresh to strong easterly 
gap winds across the Gulf of Papagayo. Moderate to fresh gap 
winds are noted in the Gulf of Panama. Light to gentle winds 
prevail elsewhere. Seas are in the 5-7 ft range over the Gulf of 
Papagayo, 4-5 ft over the Gulf of Panama, and 3-4 ft elsewhere. 

For the forecast, winds over the Gulf of Papagayo will diminish 
later in the day, then pulse again overnight. Gentle to moderate 
winds will prevail elsewhere with moderate long- period southerly
swell, except for fresh northerly winds over the Gulf of Panama 
Sat through Mon. 

...REMAINDER OF THE AREA...

The pressure gradient between a surface ridge north of 20N and
lower pressure in the vicinity of the ITCZ is supporting moderate
to fresh NE to E trade winds north of the ITCZ to 22N west of 
120W. These winds are supporting seas in the 8 to 9 ft range. 
Moderate to fresh N to NE winds and 8 to 9 ft combined seas are 
noted north of 20N and east of 125W. Light to gentle breezes are
noted elsewhere, with seas of 4 to 6 ft primarily in SW swell. 

For the forecast, high pressure will persist north of 20N 
through Fri, supporting moderate to fresh trade winds south of 
20N, west of 120W through Fri. Combined seas will subside as the 
northerly swell decays. Looking ahead, the high pressure will 
shift eastward Sat and Sun ahead of a weak cold front that will 
approach 30N140W late Sun, then stall across the waters north of 
25N and west of 120W through Mon.
