NWS National Hurricane Center Miami FL
1005 UTC Wed Apr 13 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 0600 UTC surface analysis and satellite imagery through
0830 UTC.

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

A surface trough extends from the border of Colombia and Panama 
near 07N77W to 05N85W to 07N101W to 07N118W. The ITCZ extends 
from 07N118W to 09N127W, then resumes west of a surface trough 
from 08N131W to beyond 06N140W. Scattered moderate convection is
noted from 02N to 08N between 80W and 100W. Scattered moderate and
isolated strong convection is noted from 05N to 14N between 100W
and 118W, and from 05N to 13N between 120W and 140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

The pressure gradient between high pressure north of the area 
and lower pressure over the western U.S. is supporting fresh to 
strong NW winds off Baja California Norte with gentle to moderate
winds off Baja California Sur. Moderate winds are just offshore 
Cabo Corrientes. Gentle to moderate winds are elsewhere offshore 
the open waters off Mexico. Light to gentle winds prevail over 
the Gulf of California. Seas are in the 10 to 12 ft range 
offshore Baja California Norte, and 8 to 9 ft off Baja 
California Sur. Seas of 5-7 ft are elsewhere offshore Mexico, and
1-3 ft over the Gulf of California. Patchy to areas of haze are 
possible near the coast of southwestern Mexico due to nearby 
agricultural fires.

For the forecast, fresh to strong winds will prevail offshore of
Baja California Norte through early today. Northerly swell west 
of the Baja California peninsula will gradually subside through 
the remainder of the week. Moderate winds will prevail off Cabo 
Corrientes into early Fri, then pulse to fresh to strong Sat 
night. A tight pressure gradient will develop offshore of Baja 
California Norte Sat. Winds over this area will strenghten, and 
seas will build to 8 ft, through the remainder of the upcoming 
weekend. 

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

Fresh to strong winds are noted over the Gulf of Papagayo 
region. Moderate winds are over and downstream the Gulf of 
Panama, as well as between Ecuador and the Galapagos Islands. 
Light to gentle winds prevail elsewhere. Seas are in the 4-6 ft 
range, reaching 7 ft over the Papagayo region as well as the 
waters between Ecuador and the Galapagos Islands. 

For the forecast, high pressure north of the area will support 
pulses of fresh to strong winds into the Papagayo region this 
evening, then again early Fri. Moderate winds in the Gulf of 
Panama will gradually diminish to gentle by the end of the week, 
then will increase to moderate this weekend. Gentle to moderate S
winds will prevail between Ecuador and the Galapagos Islands. 
Mainly light to gentle winds are expected elsewhere. Moderate S 
to SW swell offshore of Ecuador to the Galapagos Islands will 
subside through the end of the week.

REMAINDER OF THE AREA

High pressure prevails north of the area. The pressure gradient 
between this area of high pressure and lower pressure in the 
vicinity of the ITCZ is supporting mainly moderate to fresh 
anticyclonic flow north of the ITCZ and west of 120W. Seas within
this area are in the 7 to 10 ft range. Winds are gentle to 
moderate elsewhere, except fresh to strong north of 26N and east 
of 125W. Long period southerly swell is affecting the area mainly
south of the equator, with seas to 7 ft between 90W and 110W.

For the forecast, conditions are expected to gradually improve, 
with the majority of 8 ft seas expected to subside by Thu, and 
fresh winds diminishing by Fri. Fairly tranquil marine conditions
will then prevail for the end of the week.
