...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: The pressure gradient induced 
by broad high pressure across the Gulf of America will maintain 
fresh to near gale force N to NE gap winds across the Gulf of 
Tehuantepec through Mon morning, with gale-force winds expected 
tonight. Seas will remain rough to very rough through early Mon 
morning before winds and seas begin to steadily diminish. 

Please read the latest HIGH SEAS FORECAST issued by the National
Hurricane Center at website -

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

A surface trough extends from 09N77W to 05N95W. The ITCZ extends
from 05N95W to beyond 03N140W. Scattered showers are along the
trough. Scattered moderate convection is along the ITCZ and W of
128W. 

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

Please see SPECIAL FEATURES above for more information on the 
Gulf of Tehuantepec gale-force gap wind event. 

Strong to near gale-force N to NE winds currently extend from 
the Tehuantepec coast offshore to near 12.5N96.5W, then veer NE 
to E and continue on to near 11.5N102W. Peak seas downwind of 
Tehuantepec are estimated at 12 to 15 ft. 

Beyond this gale-force gap wind event in the Gulf of 
Tehuantepec, weak high pressure remains NW of the area, while 
broad low pressure persists from Baja Norte southward across the 
offshore waters of Baja Sur. This weak pressure pattern is 
producing gentle to moderate NW to N winds offshore of Baja 
California Norte, as indicated by recent ASCAT scatterometer 
data. Gentle to moderate SW to S winds prevail across waters of
Baja Sur and near the coast near Punta Eugenia, and are also 
wrapping around the southern end of the Baja peninsula near Cabo 
San Lucas, and into the Gulf of California. Light to gentle winds
dominate the remainder of the waters between Puerto Angel and 
the Revillagigedo Islands. Moderate seas in northerly swell 
prevail offshore Baja California and W of 110W, while slight seas
elsewhere away from and downwind of the Gulf of Tehuantepec.

For the forecast, aside from the current strong Gulf of 
Tehuantepec gap wind event, broad low pressure is expected to 
persist across the waters of Baja California through Sun then 
drift NW and dissipate through Tue. Gentle to moderate winds 
will prevail across the majority of the waters through Wed, with 
moderate to locally fresh southerly winds developing in the 
northern Gulf of California. The pressure gradient will tighten 
thereafter, as high pressure gradually builds across the area 
from the NW late Wed through Fri. Winds offshore of Baja 
California are expected to increasing to moderate to fresh by Wed
night. Slight to moderate seas will prevail through Thu, with 
moderate cross-equatorial S swell moving into the Mexican waters
Thu night.

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

Fresh to strong NE to E winds prevail over the Papagayo region 
per recent ASCAT scatterometer data, and extend southwestward to
near 93W, where seas are 6-8 ft. In the Gulf of Panama, moderate
to fresh N-NE winds prevail, and extend downwind to 03.5N, where
seas are moderate in S swell. Winds are light to gentle 
elsewhere. Moderate seas prevail across the remaining waters.

For the forecast, fresh to strong NE to E winds will pulse in 
the Gulf of Papagayo downwind to near 92W through early Wed, then
become moderate to fresh thereafter. In the Gulf of Panama, N to NE
winds will continue to pulse through early Tue, building seas  
to rough at times. Rough to very rough seas in NW swell will 
continue to spread offshore Guatemala this afternoon through 
tonight due to the Gulf of Tehuantepec gale event. Slight to 
moderate seas will prevail otherwise through Tue night. Large SW 
swell will spread to the waters from offshore Ecuador to the 
Galapagos Islands Wed and build seas to 8-9 ft Thu.

...REMAINDER OF THE AREA...

Complex low pressure system remains centered NW of the local 
area, and extends a weak stationary front across the far NW 
waters along 137W. Gentle to moderate winds prevail across the 
open waters, except fresh from 03N to 13N and W of 110W per 
recent ASCAT scatterometer data. Fresh to strong NE to winds 
extend from a strong Gulf of Tehuantepec gap wind event, beyond 
100W, into the waters near 11N101W where seas are rough. Moderate
seas in mixed swell prevail across the remainder of the waters.

For the forecast, gentle to moderate winds will dominate the open
waters through the next several days, with weak high pressure 
across much of the area and broad low pressure across Baja 
California. A series of weak frontal boundaries will move into 
the NW waters and weaken W of 130W throughout the week. N to NE 
swell generated by a gale-force gap wind event in the Gulf of 
Tehuantepec will spread SW and impact the waters roughly N of 05N
and E of 107W through Mon evening. Fresh to strong winds will 
pulse across these waters as well extending downwind from 
Tehuantepec and into the trade wind zone east of 110W. Moderate 
seas will continue otherwise through the early part of the week. 
Large southerly swell will move into the waters S of the Equator 
mid-week and reach 10N by Thu.
