Tropical Weather Discussion for the eastern Pacific Ocean from
the Equator to 32N, east of 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 
2145 UTC.

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

The monsoon trough extends from 08N78W to 09N84W to 05N93W to 
07N112W. The ITCZ begins near 07N112W to 07N130W to 07N140W. 
Scattered moderate convection and isolated tstms are from 03N to 
07N E of 91W, from 06N to 10N between 102W and 133W. A surface 
trough extends from 09N120W to 16N114W with associated scattered 
moderate convection from 10N to 17N between 108W and 119W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A cold front extends from SW NW Mexico to the coast of Baja 
California Sur near 24N112W to 20N128W. The front will continue 
to move SE while weakening tonight and dissipate near Cabo San 
Lucas Saturday morning. Fresh to strong winds are behind the 
front with the strongest winds being N of Punta Eugenia. 
Associated swell with sea heights up to 15 ft spreads to near 
Cabo San Lazaro. Winds and seas along the Baja offshores will 
diminish tonight. However, large NW swell will continue to 
propagate southeastward to the Jalisco offshore waters through 
Sunday night before subsiding. 

A new cold front is forecast to enter the Baja California 
offshore waters on Monday evening along with long period swell 
with sea height reaching 13 ft. The front will reach the region 
near Santa Margarita in Baja California Sur by Wednesday morning 
before dissipating near Cabo San Lucas during the night hours. 
Large swell with 23 second period will impact the offshores of 
Baja, Tuxpan and Jalisco through Thursday.  

Moderate to fresh NW winds are expected in the central and 
southern Gulf of California Sun and Monday. Otherwise, strong 
high pressure will build over the Gulf of Mexico early next 
week, and will support a short-lived gap wind event in 
Tehuantepec Tue and Wed. 

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

Fresh to occasionally strong winds are expected across the Gulf 
of Papagayo through the middle of the upcoming week. Otherwise, 
light to gentle variable winds will dominate elsewhere across 
the offshore waters of Costa Rica, Panama, Colombia, and Ecuador 
through Sun. Gentle to moderate S to SW winds are expected 
afterwards through Wednesday. 

REMAINDER OF THE AREA...

A weakening cold front extending from Baja California Sur near 
24N111W to 21N120W to 20N129W will continue to move SE and 
dissipate near 19N tonight. Surface ridging dominate the 
remainder waters. The pressure gradient between the ridge and 
lower pressure along the ITCZ continue to support moderate to 
fresh NE to E winds S of 22N W of 115W. Long period NW swell 
associated with the front continue to support sea heights of 8 
to 14 ft N of 07N W of 115W. The ridge will strengthen by Sat 
evening and fresh to strong winds will develop N of the ITCZ to 
near 25N through Tuesday. Otherwise, a new cold front will enter 
the northern waters on Mon and extend from central Baja to 
23N120W to 20N135W by Tue morning.
