Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Sat Mar 19 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 07N78W to 03N90W to 03N101W. The 
ITCZ continues from 03N101W to 07N123W to 06N140W. Scattered 
moderate convection is from 04N to 09N between 84W and 90W, and
from 05N to 10N W of 128W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A 1027 mb high pressure system positioned near 35N151W extends 
to near the Revillagigedo Islands. This system is producing 
mainly light to gentle NW to N winds along the Baja California 
offshore waters, with wave heights of 5-7 ft in NW swell. Gentle
to moderate NW winds are along the offshore waters of Jalisco to
Michoacan with seas to 5 ft in NW swell. Light to gentle variable
winds are elsewhere along the Gulf of California, S and SW
Mexican offshore waters.

For the forecast, a weakening cold front is forecast to approach 
the offshore waters of northern Baja California on Sat night 
into Sun, bringing an increase in winds and seas. Winds of 20-25 
kt are expected N of Punta Eugenia on Sun, with seas building to 
8-12 ft in NW swell. These winds will spread southward reaching 
the waters N of Cabo San Lazaro by Sun evening. At the same time,
fresh to strong W to NW winds are expected across parts of the 
Gulf of California. By Sun night, fresh to locally strong NW 
winds will dominate the entire Baja California offshore waters, 
including Los Cabos area. The next gap wind event in the 
Tehuantepec region is forecast Sat morning through early on Mon.
Winds could briefly reach minimal gale force on Sat night. Seas 
are expected to build up to 9 or 10 ft with this event. 

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

Moderate to fresh NE to E gap winds continue across the Papagayo
region extending to 88W. Seas across this area are in the range 
of 3-5 ft. Gentle to moderate northerly winds are in the Gulf of 
Panama where seas are 3-5 ft in SW swell. Light to gentle winds 
are elsewhere along with wave heights of 3-5 ft due to SW swell.

For the forecast, fresh NE to E winds are expected across the 
Papagayo region through Sat, then winds will increase to fresh to
strong speeds Sat night into Sun with seas building to 7 or 8 ft
by Sun night. These marine conditions will likely persist through
Tue. Moderate N winds are expected in the Gulf of Panama at 
night through Sun night. Cross equatorial SW swell will continue 
to affect the offshore waters with seas of 3-5 ft. 

REMAINDER OF THE AREA

A 1026 mb high pressure system centered near 30N134W dominates 
the waters N of the ITCZ and W of about 110W. The pressure 
gradient between this system and lower pressures near the ITCZ 
supports fresh to strong trade winds from 07N to 13N W of 135W
based on recent scatterometer satellite data. Wave heights are 
in the 8-10 ft range across this area in mixed NW swell and NE 
wind waves.

For the forecast, high pressure situated just N of the area will
continue to dominate most of the forecast waters N of the ITCZ 
and W of 110W through Sat. A weakening cold front will clip the 
northern forecast region late Sat. This will bring increasing 
NW to N winds of 20-25 kt and building seas of 8-12 ft, mainly 
across the NE waters, including the offshore waters of Baja 
California Norte Sat night into Sun.
