Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 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 0600 UTC surface analysis and satellite imagery through
0830 UTC.

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

The monsoon trough extends from 08N78W to 06N105W to 04N110W. 
The ITCZ continues from 04N110W to beyond 04N140W. Scattered 
moderate convection is noted from 03N to 07N between 83W and 
88W. 

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

Recent satellite derived data indicated mostly light to gentle 
NW winds across most of the offshore waters off Baja California, 
and moderate NW winds well offshore of Baja Norte. This is
related to a relatively weak pressure gradient across the region. 
Combined seas remain 5 to 7 ft off Baja California Norte. 
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 winds across the Mexican offshore waters
through Sat. Smoke from agricultural fires will impact the
coastal waters of southern Mexico through today. 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 late Sun and Sun 
night. 

...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 85W.
 
...REMAINDER OF THE AREA...

High pressure is displaced well north of the area ahead of a 
cold front approaching 30N140W and extending into the central 
Hawaiian Islands. This pattern is supporting moderate trade winds
north of 05N and west of 120W. Mainly gentle breezes are evident
elsewhere. Combined seas are 7 to 8 ft in northerly swell north 
of 27N and east of 128W, and 4 to 7 ft elsewhere.

For the forecast, the NW swell north of 27N and west of 120W will
diminish to less than 8 ft this morning. 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 later 
today, then stall and dissipate through Fri. 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.
