...SPECIAL FEATURES...

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 10-12 ft across this 
region. The gale force winds are forecast to continue into early 
Sat before diminishing.

Please read the latest HIGH SEAS FORECAST issued by the National
Hurricane Center at website - 
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more 
information. 

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

A surface trough extends from 07.5N82W to 05N88W. The ITCZ 
extends from 05N88W to 03N133W. Scattered moderate convection is
noted from 03.5N to 07N and east of 95.5W.

...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, except locally moderate off
Cabo San Lucas. 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, moderate to locally fresh NW winds will dominate 
offshore Baja California, with light to gentle winds elsewhere. 
Moderate seas will generally prevail, with slight seas in the 
Gulf of California. Long period N swell will arrive Sun offshore 
Baja California Norte, and this may lead to rough seas there Sun 
late night into early next week. 

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

Moderate gap winds are ongoing in the Gulf of Papagayo and Gulf
of Panama, with light to gentle winds elsewhere. Seas are 3 to 5
ft, except for 5 to 7 ft seas will offshore Guatemala due to 
gale-force gap winds N of the region in the Gulf of Tehuantepec. 

For the forecast, large N swell generated by the gale-force gap 
winds in the Gulf of Tehuantepec will impact the offshore waters 
of Guatemala into Sat. Fresh to strong winds will pulse nightly 
in the Gulf of Papagayo. Moderate to locally fresh winds will 
pulse nightly in the Gulf of Panama. Gentle breezes and moderate
seas will prevail elsewhere. 

...REMAINDER OF THE AREA...

The pressure gradient between high pressure centered N of the
area and the ITCZ is leading to gentle to moderate trades from 
the equator to 16.5N, with gentle trades to the S. Dominated by 
the ridge, waters N of 16.5N are experiencing light to gentle 
anticyclonic winds. Seas through the basin are mainly 4 to 6 ft, 
except for some locally rough seas N and E of 11N100W, where 
swell from gales in the Gulf of Tehuantepec are propagating. 

For the forecast, moderate or weaker winds and moderate seas 
will generally prevail across the region into the start of next
week. N swell will build just S of 30N from off Baja California 
Norte Sun, leading to rough seas into Mon.
