...Special Features...

Gulf of Tehuantepec gale warning: Gale-force N to NE winds to 40
kt continue in the Tehuantepec region as a tight gradient 
remains in place over southern Mexico. Peak wave heights with 
these winds are in the 13-16 ft range. These winds will diminish
to near gale-force speeds tonight and to strong speeds Mon. Wave
heights will begin to subside this afternoon and into Mon. Near 
gale-force north to northeast winds are expected Tue night and 
Wed as high pressure builds southward over eastern Mexico. For 
further details, please see the latest NWS High Seas Forecast 
issued by the National Hurricane Center, at this website:

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

A surface trough extends from northwestern Colombia near 07N78W 
to 0N91W to 05N111W to 05N118W, where it transitions to the ITCZ
and continues to 04N130W to 04N140W. Scattered moderate 
convection is within 240 nm south of the ITCZ between 96W-99W, 
and within 120 nm of trough between 90W-93W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Surface ridging anchored by a 1027 mb high near 30N131W is 
maintaining fresh northwest winds along the Baja California 
offshore waters, with wave heights of 3-5 ft due to a south to 
southwest swell. Along the Gulf of California, fresh to strong 
northwest winds continues all the way to the Nayarit offshore 
waters with wave heights of 5-6 ft. Light to gentle northwest 
winds are elsewhere along the southwestern Mexican offshore 
waters, with wave heights of 2-3 ft. 

A gap wind event is ongoing for the region of Tehuantepec with 
strong gale-force winds there. See the Special Features section 
for further details. Moderate to fresh winds will prevail off 
Baja California Norte through the middle of next week when the 
next gap wind event is forecast for Tehuantepec. 

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

A weak pressure gradient across the area is supporting light to 
gentle variable winds, with wave heights to 5 ft. Fresh to 
strong north to east winds are in the Gulf of Papagayo, while
moderate north winds are in the Gulf of Panama. Wave heights 
are up to 8 ft in the Gulf of Papagayo and to 6 ft in the 
Gulf of Panama.

Gentle winds continue will through most of the forecast period, 
except for the Papagayo region where the fresh to strong winds will 
continue through the middle of the week. Moderate northerly winds 
will also pulse in the Gulf of Panama tonight through Mon night. 

REMAINDER OF THE AREA

High pressure of 1027 mb high near 30N131W continues to extend
a ridge across the area, with the related gradient supporting 
moderate to fresh northeast to east winds and wave heights 5-8 ft
north of the ITCZ and west of 115W. Locally strong winds are 
noted from 10N to 15N west of 137W. These conditions are expected
to continue through at least late on Tue as the gradient there 
tightens. Wave heights with these winds should range from 8-11 
ft. Sporadic clusters of moderate convection are noted north of 
the ITCZ west of about 117W, and also from 09N to 11N between 
104W-110W.
