...SPECIAL FEATURES...

Tropical Storm Dalila is centered near 15.9N 103.9W at 14/0900
UTC, moving northwest at 10 kt. Estimated minimum central
pressure is 999 mb. Maximum sustained wind speed is 45 kt with
gusts to 55 kt. Seas of 12 ft and greater extend outward to 135 
nm to the northeast, and near the Mexican coast, and up to 330 
nm across the southeast quadrant. Peak seas are estimated at 17 
ft. Numerous moderate to strong convection extend from 13N to 20N
between 97W and 108W, including along the Mexican coast. A 
northwest general motion is expected to continue through today. A
gradual turn toward the west is expected tonight and Sunday. On 
the forecast track, the center of Dalila is forecast to move 
parallel to, but offshore of, the southwestern coast of Mexico. 
Some additional strengthening is expected today. Weakening is 
forecast to begin Sunday. Please refer to the latest HIGH SEAS 
FORECAST issued by the National Hurricane Center at website - 
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml and the latest T.S.
Dalila NHC Forecast Advisory and Public Advisory at

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

The monsoon trough extends from 10N85W to 13N98W, then resumes 
west of T.S. Dalila near 12N111W to 06N136W. The ITCZ extends 
from 06N136W to beyond 06N140W. Aside from the convection 
associated with T.S. Dalila, scattered to numerous moderate to 
strong convection is noted from 06N to 12N between 81W and 91W, 
and from 06N to 11N between 108W and 124W. 

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

Please read the Special Features section for information on 
Tropical Storm Dalila, located a few hundred miles southwest of 
Acapulco, Mexico.

Broad cyclonic flow associated with Dalila dominates the SW
Mexican offshore waters. Elsewhere, a broad and weak ridge 
extends from a 1029 mb high centered well NW of the area near 
39N138W to just west of Guadalupe Island. This continue to 
support gentle to moderate NW winds across the offshore waters of
Baja California where seas are 5 to 7 ft in NW swell. Light to 
gentle winds are ongoing in the Gulf of California with seas less
than 3 ft, except in the entrance of the Gulf where seas are 3 
to 5 ft. Light to gentle winds are also across the Gulf of
Tehuantepec with seas to 10 ft in mixed swell. 

For the forecast, T.S. Dalila will move NW today and gradually 
strengthen to 55 kt. Dalila will move to 16.7N 105.0W this 
afternoon, 17.6N 107.1W Sun morning, 18.0N 109.3W Sun afternoon, 
18.1N 111.2W Mon morning, weaken to a remnant low near 18.0N 
113.0W Mon afternoon, and 17.8N 115.2W Tue morning. Dalila will 
dissipate early Wed. Moderate-sized cross-equatorial southerly 
swell will mix with seas generated from Dalila to impact the 
waters between Tehuantepec and Cabo Corrientes through Sun. 
Elsewhere, high pressure well northwest of the area will support 
generally moderate to locally fresh N-NW winds across the Baja 
California offshore waters through Wed. NW to N swell will build
into the Baja waters Sun through Wed.

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

A tropical wave moving from Honduras to Costa Rica is generating
heavy showers and tstms across the Nicaragua and Costa Rica
offshore waters, with gusty winds and rough seas likely ongoing.
Winds elsewhere are moderate or weaker. Seas across most of
Central America offshores are 7 to 10 ft in SW swell. Between
Ecuador and the Galapagos, seas 5 to 8 ft in SW swell.

For the forecast, large SW swell will persist through most of 
the weekend, then subside early next week. Tropical Storm Dalila
located southwest of Acapulco, Mexico will move NW through today
then turn more W-NW and weaken Sun into Mon. SW swell from this 
system will continue to impact the waters of El Salvador and 
Guatemala through today. Showers and thunderstorms are expected 
to remain active across the Central America waters over the 
weekend and into early next week. 

...REMAINDER OF THE AREA...

Please read the Special Features section for information on 
Tropical Storm Dalila, located a few hundred nautical miles 
southwest of Acapulco, Mexico.

Broad and weak ridging dominates the waters north of 13N, 
centered on a 1029 mb high near 39N138W. This pattern is 
supporting mostly moderate N to NE winds north of 10N and west 
of 120W, with 5 to 7 ft seas in a mix of N and S swell. Southerly
swell of 8 to 10 ft is gradually subsiding between 90W and 115W.
Elsewhere moderate to fresh SW winds persist south of the 
monsoon trough between 100W and 115W. Seas are 5 to 6 ft in S 
swell elsewhere west of 120W.

In the forecast, little change is expected west of 120W except
for increased NW swell north of 28N and east of 130W today 
through Wed. Conditions east of 120W and associated with T.S. 
Dalila are described in the Special Features section above, and 
will be dominated by large SW swell through tonight, and mixed E
to SE swell generated by Dalila. Dalila is forecast to die off by
Tue afternoon.
