NWS National Hurricane Center Miami FL
1605 UTC Mon Apr 11 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

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

A surface trough extends from 06N77W to 05N105W to 06N103W. ITCZ
from 06N120W to 02N140W. Scattered moderate isolated strong 
convection is noted from 00N to 05N east of 83W, from 02N to 08N 
between 86W and 107W, and from 03N to 13N between 110W and 130W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

High pressure over the eastern Pacific and lower
pressure over the southwest U.S. is supporting fresh to strong
winds off Baja California Norte and the northern Gulf of
California through into early Tue, ahead of a cold front moving
through the region Tue morning. Northerly swell will prevail 
west of the Baja California peninsula today. Fresh to strong NW 
winds are expected behind the front to the west of Baja 
California Norte, with fresh winds off Baja California Sur. A 
reinforcing set of northerly swell will enter the area behind the
front. This will maintain wave heights in excess of 8 ft west of
the Baja California peninsula through early Thu. 

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

High pressure north of the area will support pulses of fresh to 
strong winds into the Papagayo region into mid week. Fresh winds 
will pulse in the Gulf of Panama tonight, gradually diminishing 
to gentle through midweek. Gentle to moderate S winds will 
prevail between Ecuador and the Galapagos Islands through the 
next few days. Mainly light to gentle winds are expected 
elsewhere. S to SW swell will increase seas through early Tue to 
the south of the Galapagos Islands and well to the west of 
Ecuador.

REMAINDER OF THE AREA

1034 mb high pressure is centered north of the area near 
36N142W. This pressure gradient between this area of high 
pressure and low pressure off the coast of California is 
producing fresh to strong NE winds over the waters north of 25N 
between 120W and 130W. Seas in this area are in the 10-14 ft 
range. Moderate to locally fresh trade winds are elsewhere north 
of the ITCZ and west of 120W, with gentle to moderate winds 
prevailing elsewhere. Seas are in the 6-8 ft range. Southern 
Hemisphere swell is affecting the area south of 05N between 100W 
and 120W, with seas in the 8-9 ft range.

For the forecast, the area of fresh to strong winds over the
northwest part of the area will start to diminish today. Swell 
generated from these winds will spread southward, with seas 
greater than 8 ft covering much of the waters north of 10N and 
west of 115W by tonight. A cold front will enter the northern 
waters by early Tue morning, then extend from 31N113W to 26N121W 
to 30N134W by midday Tue. The front will continue southward 
before dissipating Tue night. The front will bring a reinforcing 
northerly swell to the area east of 125W and north of 22N Tue 
through Wed. Southerly swell from the Southern Hemisphere will 
continue to affect areas south of 05N between the Galapagos 
Islands and 125W through the early part of next week.
