NWS National Hurricane Center Miami FL
0405 UTC Mon Feb 20 2023

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
0200 UTC.

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

A surface trough extends from 08N82W to 00N103W. The ITCZ 
continues from 00N103W to 03N140W. Scattered moderate convection
is noted from 02N to 08N between 120W and 132W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Strong to near gale force winds prevail over the Tehuantepec 
region, with seas to 9 ft. Light to gentle winds prevail west 
of the Baja California peninsula. Elsewhere, gentle to locally 
moderate winds prevail. Seas are in the 4-6 ft range over the 
open waters, and 1-3 ft over the Gulf of California.

For the forecast, strong to near-gale force N winds will prevail
over the Tehuantepec region through Mon. Winds and seas will 
continue to decrease in the area through the week. Light to 
gentle winds will prevail elsewhere across the open waters off 
Mexico, increasing modestly beginning on Tue. Light to gentle NW 
winds will prevail across much of the Gulf of California, briefly
strengthening to moderate to fresh over the northern Gulf by 
midweek. A new set of NW swell will propagate into the waters off
Baja California by midweek. 

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

Strong to near-gale NE winds prevail across the Gulf of 
Papagayo, extending downwind to near 89W along with seas of 8 to
10 ft. Fresh to strong N winds are in the Gulf of Panama, where 
seas are in the 5 to 8 ft range. Light to gentle winds prevail 
elsewhere along with seas of 4-5 ft primarily in long-period S to
SW swell.

For the forecast, strong to near-gale NE to E winds in the Gulf of
Papagayo region will persist through early this week, with rough
seas. Fresh to strong N to NE winds will prevail in the Gulf of 
Panama through Mon. Swell generated from the Gulf of Tehuantepec 
gap wind event will maintain large northerly swell over the 
Guatemala and El Salvador waters through Mon. 

REMAINDER OF THE AREA...

High pressure prevails across the waters N of 20N and W of 120W.
The pressure gradient between the ridge and lower pressure in 
the vicinity of the ITCZ supports an area of moderate to fresh 
trades N of the ITCZ and W of 120W. Seas are 8-11 ft in a mix of
long-period N swell and NE wind waves over these waters. 
Elsewhere, winds are moderate or weaker with seas of 6-8 ft 
primarily in northerly swell.

For the forecast, fresh NE to E trade winds are forecast to 
persist over the west-central waters through Mon, with little 
change to seas within this part of the area.
