Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Wed Apr 26 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
2000 UTC.

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

The monsoon trough extends from 10N74.5W to 06N92W to 07.5N105W 
to 05.5N110W. The ITCZ continues from 05.5N110W to 04N124W to 
beyond 02.5N140W. Widely scattered moderate isolated strong 
convection is noted from 00N to 09N E of 100W, and from 02N to 
04N between 129W and 132W.

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

Recent satellite derived wind data indicates mostly gentle NW 
winds across most of the offshore waters off Baja California, and
moderate NW winds near the prominent points of Cabo San Lucas and 
Punta Eugenia. This light wind flow is the result of a relatively
weak pressure gradient across the region. Combined seas have
subsided to 5 to 7 ft off Baja California Norte, and 4 to 6 ft
off of Baja Sur. Elsewhere gentle winds and slight seas are 
noted over the Gulf of California and off southern Mexico. Areas 
of smoke from agricultural fires persist off southern Mexico.

For the forecast, the relatively weak pressure pattern will 
support gentle to moderate NW winds across the Mexican offshore 
waters through early Sun. Looking ahead, high pressure building
behind a cold front moving through the Gulf of Mexico will 
support fresh to strong gap winds and building seas across the 
Gulf of Tehuantepec Sun through Mon morning. High pressure will 
also build across the Baja Norte waters Sun through Mon to 
produce freshening NW winds.

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

Light to gentle breezes and slight to moderate combined seas in 
SW swell dominate the region. For the forecast, a weak pressure
gradient will support light to gentle mainly onshore breezes 
across the region through late week, except for gentle to
moderate northerly winds across the Gulf of Panama. Expect 
slight to moderate combined seas primarily in S to SW swell. 
Also, areas of smoke from agricultural fires may persist over the
offshore waters W of 84W.
 
...REMAINDER OF THE AREA...

High pressure is displaced well north of the area, and offshore
of Oregon, ahead of a cold front that is approaching 30N140W this
afternoon, and extends into the central Hawaiian Islands. Fresh
southerly winds and seas to 7 ft have shifted into the far NW
waters ahead of the front, to the N of 29N and W of 139W. The
pressure pattern across the region is supporting gentle to 
moderate trade winds north of 06N and west of 120W. Mainly gentle
breezes are evident elsewhere. Combined seas are 6 to 7 ft in 
northerly swell north of 20N and east of 128W, and 5 to 7 ft 
elsewhere.

For the forecast, the NW swell E of of 128W will continue to
gradually subside through Thu. Moderate trade winds will persist
from 05N to 20N and west of 125W through the remainder of the 
week. The cold front will reach 30N140W early Thu morning, then 
stall and dissipate through Fri. Expect a brief period of fresh
southerly winds and seas to 7 ft near 30N140W this afternoon
through tonight, with winds and seas higher to the N. Strong 
high pressure will build into the region from the NW over the 
weekend and produce fresh to strong N to NE winds and increasing 
N swell to the north of 25N by late Sun.
