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
0130 UTC.

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

A surface trough extends from 08N87W to 03N100W. The ITCZ 
extends from 03N100W to 00S140W. Scattered moderate convection 
is noted from 00N to 04N between 100W and 108W.

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 into early next week.
Elsewhere, mostly benign marine conditions will prevail through
Tue night. Otherwise, moderate or less winds will dominate waters
into early next week. 

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 into Fri, then 
increase again starting Sun night. 

REMAINDER OF THE AREA...

High pressure of 1020 mb is analyzed near 22N125W. Moderate to 
fresh winds, and seas of 6-7 ft, are noted N of 22N 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 through Fri. High pressure will build along 23N to 24N 
this weekend, maintaining the moderate to fresh tradewinds over
the tradewind zone. A cold front may enter the NW waters Mon,
inducing increasing winds and seas N of 25N and W of 130W.
