Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Fri Mar 17 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 0600 UTC surface analysis and satellite imagery through
0800 UTC.

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

A surface trough extends from 08N92W to 02N101W. The ITCZ 
extends from 02N102W to 00N140W. Scattered moderate convection 
is noted from 00N to 06N between 94W and 101W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Gentle to moderate winds are found west of the Baja California 
peninsula. Light to gentle winds prevail elsewhere across the 
open waters off Mexico, as well as the Gulf of California. Seas 
are in the 4 to 6 ft over the offshore waters, except 1 to 3 ft
in the Gulf of California. 

For the forecast, fresh to strong gap winds will develop in the Gulf
of Tehuantepec Sat night and continue through early next week. 
Elsewhere, mostly benign marine conditions will prevail into Tue
night. Tue night, SW gap winds may develop in the northern Gulf
of California. 

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND 
WITHIN 750 NM OF ECUADOR...
 
Light to gentle winds prevail over the offshore waters of 
Central America and South America. Seas are in the 3-5 ft range 
in long-period S to SW swell.

For the forecast, light to gentle winds will prevail over the
offshore waters through much of the forecast period. Winds in
the Papagayo region may pulse at times to moderate this morning,
then increase again starting Sun night. 

REMAINDER OF THE AREA...

High pressure of 1020 mb is analyzed near 22N125W. Moderate to
locally fresh winds, and seas of 6-7 ft, are noted N of 24N and 
W of 125W. Elsewhere, the pressure gradient between the area of 
high pressure and lower pressure in the vicinity of the ITCZ is 
producing mainly moderate trade winds N of the ITCZ to near 15N 
and W of 120W. Light to gentle winds, and seas of 4-6 ft, prevail
elsewhere across the discussion waters. 

For the forecast, moderate to fresh winds over the NW waters will
decrease today. High pressure will build along 23N to 24N this 
weekend, maintaining the moderate to fresh tradewinds over the 
tradewind zone. A cold front is likely to enter the NW waters 
Mon, possibly inducing increasing winds and seas N of 25N and W 
of 130W.
