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 
2100 UTC.

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

A tough extends from the coast of Colombia near 0677W to 06N87W. 
The ITCZ continues from 06N87W to 02N103W to 01N130W. Scattered 
moderate rain showers are within 30 nm of the ITCZ between 94W 
and 99W. Scattered moderate isolated strong showers are within 
120 nm N of the ITCZ between 122W and 130W.

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...  

Gulf of Tehuantepec: Strong winds across the Gulf of Tehuantepec 
will diminish overnight. The next gap wind event is forecast to 
begin on Mon, with gale force winds possible Mon night.

Gulf of California: Fresh NW winds will continue in the Gulf of 
California through the weekend.

The pressure gradient will tighten between the subtropical high 
and low pressure over northern Mexico tonight, allowing NW winds 
to become fresh to strong, and continue into Sat. Wave heights 
will build to 10-11 Ft on Fri, then diminish this weekend. 

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

Gulf of Papagayo: Strong winds will continue to pulse in the 
Gulf of Papagayo through Fri morning. Winds will become moderate 
to fresh this weekend.

Gulf of Panama: Fresh northerly winds in the Gulf of Panama will 
continue overnight, then diminish Fri and Sat.

REMAINDER OF THE AREA...

A trough extends from 30N127W to 22N136W. NW swell to 7-8 ft N 
of 24N between 123W and 134W will continue to decay overnight.

A cold front will weaken and stall near 30N140W on Fri. The 
front will introduce more long-period NW swell that will sweep 
across the area through Sat.

The gradient between high pressure near 30N and lower pressure 
in the tropics is producing an area of fresh to strong trade 
winds west of 125W, with seas of 9 to 10 ft. This area of winds 
and seas is expected to change little over the next couple of 
days, then diminish Sat and Sun as the gradient weakens. 

A combination of longer period northwest and southwest swell is 
maintaining an area of 8-11 ft seas south of 25N west of 110W, 
and south of 08N between 94W and 110W. These seas will change 
little through the weekend.
