Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Mon Mar 7 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 Colombia near 10N75W to 05.5N80.5W
to 07N88W to 04N106W. The ITCZ stretches from 04N106W to 
08N129W to beyond 07N140W. Scattered moderate convection is noted 
S of 02N between 87W and 92W and from 03N to 10N between 104W 
and 117W. Scattered to locally numerous moderate to strong 
convection is noted from 06N to 11N between 123W and 137W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A relatively narrow surface ridge extends from strong high
pressure across the Pacific NW through 30N130W to near 18N108W.
The pressure gradient between this ridge and lower pressure
across the Sierra Madre Occidentales of Mexico is producing mainly
fresh NW to N winds within 150 nm offshore of Baja California N
of Cabo San Lazaro, and moderate N winds elsewhere southward to 
19N. Seas are 7 to 9 ft in NW swell offshore of Baja Norte and 6
to 8 ft elsewhere. Moderate side shore winds are occurring near
the coast along Cabo Corrientes and Puerto Angel. Otherwise to
the S of 19N, winds are light and seas are 4 to 6 ft.

Inside the Gulf of California, fresh northerly winds prevail
south of the Tiburon Basin, where seas are 3-5 ft, except to 6 ft
at the mouth of the Gulf.

Fresh to locally strong NW winds offshore Baja California Norte 
today will diminish some tonight. NW swell and current seas of 7
to 9 ft will also decay in this area. As high pressure builds 
toward the region, fresh NW winds in the Gulf of California will 
increase to strong tonight, then prevail through Tue. Elsewhere, 
gentle to moderate winds and 5 to 7 ft seas will prevail into 
mid-week. Looking ahead, gales are likely to develop in the Gulf 
of Tehuantepec next weekend. 

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

Fresh NE to E winds are noted across the Papagayo region, with 
some moderate N winds in the Gulf of Panama. Elsewhere, winds are
light to gentle with seas of 3 to 5 ft.

Fresh northeast winds in the Gulf of Papagayo region will 
gradually diminish tonight, then decrease further to gentle to 
moderate through the end of the week. Moderate north winds in the
Gulf of Panama will pulse nightly through mid week becoming 
light to gentle the remainder of the week. Gentle to moderate 
winds will prevail elsewhere. New SW swell will mix with WNW
swell across the regional waters on Thu to raise seas slightly.

REMAINDER OF THE AREA

N of the ITCZ to 20N, widespread moderate to fresh NE to E winds
prevail due to the pressure gradient between the ITCZ and the 
high pressure to the north. Seas are 8 to 11 ft in mixed swell. 
Across NW portions, fresh to strong SE winds N of 25N and W of 
138W are associated with a trough west of the area. Scattered
moderate convection is seen on satellite imagery there from 25.5N
to 28N W of 139W. To the S of the ITCZ, gentle to moderate E to 
SE winds prevail with seas of 4 to 6 ft.

Winds will subside across northern waters as the pressure 
gradient weakens, except just N of the ITCZ and W of 130W, where 
fresh trades and seas of 8 to 10 ft will prevail most of the 
week. The trough W of the area will weaken, allowing winds to 
relax to fresh and seas to fall under 8 ft by midweek.
