Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Sat Apr 6 2024

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...

A surface trough extends from 1010 mb low pressure over northern
Colombia to 06N88W. The ITCZ continues from 06N88W to 06N105W to
06N124W, then resumes W of a surface trough at 03N136W to beyond
03N140W. The surface trough extends from 07N126W to 02N134W. 
Scattered moderate convection is noted from 04N to 08N between 
the coast of Colombia and 90W, and from 06N to 10N between 112W 
and 124W. Scattered moderate to isolated strong convection from 
02N to 05N W of 130W.

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

A weakening frontal boundary crosses the central Gulf of California.
Fresh to strong NW to N winds and seas of 4 to 6 ft are noted near
the front. Strong high pressure of 1039 mb located N of the Hawaiian
Islands extends a ridge eastward towards the Baja California offshore
waters. This system combined with a low pressure over northern 
Mexico supports the previously mentioned fresh to strong winds 
in the central Gulf of California, and also an area of fresh to 
strong NW to N winds, with seas of 8 to 10 ft just W of Baja 
California Sur to about 116W. Gentle to moderate NW to N winds 
are observed across the remainder of the Mexican offshore waters 
with seas of 3 to 5 ft. 

For the forecast, a ridge will continue to dominate the offshore
forecast waters of Baja California. Winds and seas will diminish
some this weekend, then expect fresh to strong Nw winds and
building seas on Mon as the pressure gradient tighten across the
area, and a reinforcing set of NW swell arrives. In the Gulf of
California, fresh to strong NW to N winds are forecast to persist
over parts of the Gulf, particularly the southern one through
early Sun morning. mainly gentle to moderate winds will prevail
elsewhere with slight to moderate seas.

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

Moderate to fresh NE to E winds are ongoing in the Papagayo
region with seas in the 4 to 6 ft range. Light to gentle 
winds are elsewhere across the Central America offshore waters 
as well as the offshore waters of Colombia, and between Ecuador 
and the Galapagos Islands. Seas are generally 3 to 5 ft, except 
to 6 ft SW of the Galapagos Islands due to SW swell. Light smoke
from agricultural fires has been noticed over coastal areas of
northern Central America for the past several days.

For the forecast, pulsing moderate to fresh NE to E winds are 
expected in the Papagayo region through at least Tue with seas in
the 4 to 6 ft. Light to gentle winds and slight to moderate seas
in SW swell are forecast elsewhere. 

...REMAINDER OF THE AREA...

High pressure dominates the waters N of 15N and W of 110W. The 
pressure gradient between this system and lower pressure in the 
vicinity of the ITCZ supports an area of fresh to strong trade 
winds mainly from 05N to 24N W of 120W with seas of 8 to 11 ft in
NE swell. Gentle to moderate winds and moderate seas are noted 
elsewhere.

For the forecast, high pressure will remain in control of the
weather pattern across most of the waters N of the ITCZ and W of
110W. As a result, a large area of fresh to strong trades will 
persist over the west-central waters through at least Monday.
