NWS National Hurricane Center Miami FL
2205 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 1800 UTC surface analysis and satellite imagery through
2020 UTC.

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

A surface trough extends from 08N77W to 07N89W to 04N96W to 
04N115W. The ITCZ continues from 04N115W to beyond 04N140W. 
Scattered moderate convection is noted south of 08N and east of 
93W.

...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 
and moderate winds west of the Baja California peninsula. Light 
to gentle winds are noted elsewhere. Seas are in the 4-5 ft 
range over the Gulf of California and 6-7 ft west of the Baja 
California peninsula. Seas of 4-6 ft prevail elsewhere. 

For the forecast, moderate to fresh winds over the Gulf of 
California will diminish this evening. 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 gap winds are 
noted in the Gulf of Panama. Light to gentle winds prevail 
elsewhere. Seas are in the 5-6 ft range over the Gulf of 
Papagayo, 4-5 ft over the Gulf of Panama, and 3-4 ft elsewhere. 

For the forecast, fresh to strong easterly gap winds will 
prevail across the Gulf of Papagayo through tonight. 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, along with northerly swell, are supporting 
seas in the 8 to 9 ft range. Moderate N to NE winds and 7 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.
