Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Mon Apr 4 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 1800 UTC surface analysis and satellite imagery through
2030 UTC.

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

A surface trough extends from 07N77W to 05N118W to 07N124W to 
05N130W. The ITCZ continues from 05N130W to 04N140W. Scattered 
moderate isolated strong convection is noted from 02N to 08N east
of 93W, and from 01N to 07N between 100W and 110W. Scattered
moderate convection is noted from 01N and 06N between 110W and
120W, and from 06N to 10N between 120W and 126W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A ridge of high pressure prevails west of the Baja California
peninsula. The pressure gradient between the ridge and a surface
trough over the Gulf of California is supporting moderate to fresh
winds west of Baja California Norte, and moderate to locally fresh
winds west of Baja California Sur. Light to gentle winds prevail
elsewhere over the discussion waters. Seas are in the 7-10 ft 
range off Baja California Norte, 6-7 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 beginning to 
subside. In the Gulf of California, light to gentle winds will 
dominate through Wed night and increase to moderate to fresh 
speeds Thu and Fri. Gale- force gap winds are possible in the 
Gulf of Tehuantepec Fri and Fri night. 

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.
