Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

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

The monsoon trough extends from 10N74.5W to 05.5N87W to 07.5N106W
to 07N111W. The ITCZ continues from 07N111W to beyond 05N140W. 
Widely scattered moderate convection is noted from 01.5N to 12N 
E of 99W, and from 03N to 07.5N between 115W and 131W.

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

Overnight satellite derived wind 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 the result of a relatively weak pressure gradient across
the region. Combined seas remain 5 to 8 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 06N 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 125W, 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 by midday. 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. Expect a brief period of
southerly winds and seas to 7 ft near 30N140W this afternoon,
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.
