Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Tue Apr 5 2022

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 0000 UTC surface analysis and satellite imagery through
0350 UTC.

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

A surface trough extends from 06N77W to 04N91W to 07N111W to 
04N128W. The ITCZ continues from 04N128W to 04N140W. Scattered 
moderate convection is noted from 00N to 10N east of 89W, and 
from 00N to 10N between 102W and 120W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A 1025 mb high centered near 32N139W continues to extend a ridge
SE to the Baja California peninsula offshore waters. The pressure
gradient between the ridge and a surface trough over the Gulf of
California is supporting moderate to fresh NW winds west of Baja
California Norte, and moderate to locally fresh winds west of 
Baja California Sur. Light to gentle winds prevail elsewhere, except
for moderate NW winds along the SW Mexican adjacent waters. Seas
are in the 7-10 ft range off Baja California Norte, 5-7 ft off 
Baja California Sur, 1-3 ft over the Gulf of California, and 4-6 
ft over the remainder of the open waters off Mexico. 

For the forecast, moderate to fresh NW winds west of Baja California
will continue into Tue morning before diminishing. Northwest 
swell affecting the offshore waters of Baja California Norte will
reach Baja California Sur Thu before subsiding Thu night. In the
Gulf of California, light to gentle winds will dominate through 
Wed night and increase to moderate to fresh speeds Thu and Fri. A
low and associated surface trough developing in southern 
California Saturday will lead to moderate to fresh SE winds along
the Gulf of California Sat and Sat night. Gale-force gap winds 
are possible in the Gulf of Tehuantepec Fri and Sat morning.

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

Light to gentle winds prevail across most of the forecast waters,
reaching moderate speeds over the Gulf of Papagayo. Seas are in 
the 4-6 ft range, mainly in S to SW swell. 

For the forecast, moderate to locally fresh easterly winds will 
pulse at night in the Papagayo region through the week, pulsing 
to strong speeds this weekend. Mainly light to gentle winds are 
expected over the rest of the offshore waters through the end of 
the week. Seas over the forecast waters will be mainly driven by 
a moderate S to SW swell. 

REMAINDER OF THE AREA

High pressure prevails over the waters north of 20N, anchored by
a 1028 mb high that is centered NW of the area near 32N149W. The
pressure gradient between this feature and the equatorial trough
is supporting moderate to fresh winds north of 06N and west of
120W. Seas over this area are mainly in the 7-10 ft range. 
Elsewhere, light to gentle winds prevail, with seas in the 5-6 ft
range. 

For the forecast, the ridge is forecast to gradually weaken
through Thu in response to an approaching cold front. Fresh NE 
to E winds N of 06N and W of 120W will diminish to moderate 
speeds midweek. A new set of NW swell is forecast to affect the 
NW forecast waters on Fri as a result of the passage of the cold 
front. Otherwise, cross-equatorial southerly swell is forecast to
propagate through the waters south of 01N and between the 
Galapagos Islands and 120W through the middle of the week.
