Gulf of Tehuantepec Gale Warning: the pressure gradient between 

high pressure across eastern Mexico and the equatorial trough is

supporting gale-force N-NE winds in the Gulf of Tehuantepec. 

Seas are 8-10 ft across this region. The gale force winds are 

forecast to continue into early Sat before diminishing. Winds 

may briefly lower to just below gale- force Fri afternoon. Seas 

will peak at 13 to 14 ft tonight. 



Please read the latest HIGH SEAS FORECAST issued by the National

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



A surface trough extends from 08N78W to 04N96W. The ITCZ extends

from 02N101W to beyond 00N140W. Scattered moderate convection is

noted from 04N to 12N between 121W and 129W.



...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...



Please see Special Features above for information on a gale 

warning in the Gulf of Tehuantepec. 



Aside from the Gulf of Tehuantepec, a weak pressure gradient is 

generating light to gentle winds. Moderate seas prevail over the

open waters, with slight seas in the Gulf of California.



For the forecast aside from the Gulf of Tehuantepec gale warning,

a weak pressure gradient will support light to gentle winds, 

increasing to moderate to fresh near Baja California this 

weekend as the pressure gradient tightens slightly. Moderate seas

will prevail over the open waters, with slight seas in the Gulf 

of California. Seas may build in fresh N swells off Baja 

California Norte late in the weekend into early next week. 



....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, 

AND WITHIN 750 NM OF ECUADOR...



Light to gentle winds and moderate seas in the 3-6 ft range 

prevail across the discussion waters, except for in the Gulf of

Papagayo, where moderate gap winds have developed.



For the forecast, large NW swell generated by the gale-force gap

winds in the Gulf of Tehuantepec will impact the offshore waters

of Guatemala Fri. Fresh to locally strong winds will pulse 

nightly in the Gulf of Papagayo starting tonight. Moderate winds 

will pulse in the Gulf of Panama starting tonight, then pulse to 

moderate to fresh into early next week. Gentle breezes and 

moderate seas will prevail elsewhere. 



...REMAINDER OF THE AREA...



A weak pressure gradient across the area is supporting mostly 

gentle to moderate winds across the open waters. Moderate wave 

heights in the 4-6 ft range prevail.



For the forecast, moderate or weaker winds and moderate seas 

will prevail across the region into the weekend. Fresh N swell 

is likely to build S of 30N from off California by the end of 

the weekend.
