Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Tue Mar 8 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 Colombia near 10N75W to 06N82W to 
04N113W. The ITCZ extends from 04N113W to 07.5N133W to beyond 
06.5N140W. Scattered moderate isolated strong convection is 
noted within 180 nm N of ITCZ W of 116W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A surface ridge extends from strong high pressure across the NE 
Pacific south and southeastward through 30N133W to near 21N116W.
The pressure gradient between this ridge and lower pressure 
across the Sierra Madre Occidentales of Mexico is producing 
moderate N winds within 150 nm offshore of Baja California N of 
Cabo San Lazaro, and gentle to moderate N winds elsewhere 
southward to 18N. Seas are 5 to 8 ft in NW swell across the 
offshore waters N of Cabo San Lazaro, and 4 to 7 ft elsewhere. 
To the S of 18N, winds are light to gentle and seas are 3 to 6 
ft. Inside the Gulf of California, fresh to locally strong 
northerly winds prevail, with seas of 4 to 7 ft.

Fresh to locally strong NW winds in the Gulf of California will 
continue into this evening before diminishing tonight. 
Elsewhere, gentle to moderate winds will prevail through mid-
week. Looking ahead, a cold front will move down the Gulf of 
California Thu afternoon through night, and bring strong winds 
to the Gulf behind it through Sat. Peak seas will build to 9 ft. 
Then on Sat, strong gales will develop in the Gulf of Tehuantepec,
and continue through the weekend.

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

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

Gap winds across the Papagayo region will become easterly and pulse
to fresh again tonight, then gradually diminish through the end 
of the week. Moderate north winds in the Gulf of Panama will also
pulse tonight, then become light to gentle the remainder of the 
week. Mainly gentle winds will prevail elsewhere.

REMAINDER OF THE AREA

1036 mb high pressure across the NE Pacific near 43W136W supports
widespread mainly fresh NE to E winds between the ITCZ and 21N, 
to the W of 120W. Seas are 8 to 11 ft in mixed swell. Across far
NW portions, fresh SE winds are N of 27N and W of 138W 
associated with the pressure gradient between a cold front west 
of the area and high pressure. To the S of the ITCZ, gentle to 
moderate E to SE winds prevail with seas of 5 to 7 ft.

Winds will subside across waters N of 25N as the ridge remains in
place while slowly weakening. However, the pressure gradient S 
of 25N and W of 122W will support fresh trades and seas of 8 to 
10 ft most of the week. The front W of the area will weaken, 
allowing winds to relax to fresh and seas to fall under 8 ft 
late this afternoon and evening. Winds and seas will diminish
significantly by the weekend as a cold front approached far NW
portions of the discussion area.
