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

The monsoon trough extends from 09N84W to 10N106W to low pres
near 08N114W to 06N120W. The ITCZ continues from 06N120W to
05N132W. Scattered moderate isolated strong convection is noted

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Fresh to strong NW winds prevail off the coast of Baja 
California Norte. Fresh to strong winds are also noted over much
of the Gulf of California as well as the Gulf of Tehuantepec.
Moderate winds are over the waters west of Baja California Sur,
with light to gentle winds elsewhere over the open waters off
Mexico. Seas are in the 7-9 ft range west of the Baja California
peninsula, 4-7 ft over the Gulf of California and Gulf of
Tehuantepec, and 4-5 ft elsewhere. 

For the forecast, fresh to strong winds will prevail over the 
Gulf of Tehuantepec through early Fri. Fresh to locally strong 
winds will persist off Baja California through late Fri between 
high pressure over the eastern Pacific and lower pressure over 
northern Mexico. NW swell in excess of 8 ft will persist off Baja
California through Fri. This pattern will also support fresh to 
strong winds over the Gulf of California tonight. 

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

Gentle to moderate S to SW monsoonal winds are noted across the
South American offshore waters. Light to gentle winds prevail
elsewhere, except reaching moderate speeds in the Gulf of 
Papagayo. Seas are in the 4-6 ft range over the waters between 
Ecuador and the Galapagos Islands and 4-5 ft elsewhere. 

For the forecast, moderate to fresh gap winds will prevail 
across the Papagayo region and southern Nicaragua through early 
Fri, with fresh to occasionally strong pulses possible Fri night 
into Sat. Gentle to moderate winds will prevail elsewhere. Long- 
period southerly swell in the region will build slightly this 
weekend.

REMAINDER OF THE AREA...

High pressure prevails over the waters north of 10N and west of 
110W. Low pressure has developed within the monsoon trough near
08N114W. Fresh to strong N to NW winds and 7 to 11 ft seas 
prevail north of the ITCZ and monsoon trough. Gentle to moderate 
SE winds and 5 to 7 ft seas are noted south of 10N and west of 
110W. East of 110W, gentle to moderate winds are noted on either 
side of the monsoon trough with 4 to 6 ft seas. 

For the forecast, the area of high pressure will start to weaken
Friday into the weekend, allowing for winds and seas to 
diminish. The area of low pressure will move westward within the
monsoon trough with fresh to occasionally strong winds and seas 
of 8 to 9 ft.
