...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: A strong high pressure system
centered over the central United States continues to support
strong to gale-force N winds and rough seas in the Gulf of
Tehuantepec. Winds will diminish below gale force early tonight.
Winds and seas will further diminish Sat as the high pressure
north of the area shifts eastward and the pressure gradient
loosens. Please refer to the latest NHC High Seas Forecast at
website https://www.hurricanes.gov/text/MIAHSFEP2.shtml for more
details.

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

The monsoon trough extends from 08N84W to 06N93W to 10N110W to
10N117W. The ITCZ stretches from 10N117W to beyond 06N140W.
Scattered moderate and isolated strong convection is observed
from 03N to 09N and east of 93W, and from 07N to 20N and between
100W and 115W. Similar convection is found from 04N to 10N and
west of 129W.

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

Please refer to the Special Features section for details on an
ongoing Gale Warning in the Gulf of Tehuantepec.

Outside of the Gulf of Tehuantepec, the Mexican offshore waters
are dominated by a subtropical ridge located west of southern
California. Moderate northerly winds and moderate seas are
occurring from the southern Gulf of California to off Cabo
Corrientes and south of Cabo San Lazaro to the Revillagigedo
Islands. Elsewhere, light to gentle winds and slight to moderate
seas prevail.

For the forecast, high pressure north of the Gulf of Tehuantepec
will continue to support gale force gap winds and rough seas through
early tonight. Fresh to strong winds will then persist in the
Gulf of Tehuantepec into early next week before diminishing. A
surface trough may impact the waters near the Revillagigedo
Islands this weekend, with fresh to locally strong winds and
rough seas possible this weekend into Mon. No significant swell
events are forecast through the upcoming weekend.

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

A strong ridge positioned well north of the area supports fresh
to strong easterly trade winds across the Gulf of Papagayo and
downstream to 92W. This was confirmed by satellite-derived wind
data a few hours ago. Seas in these waters are 6-8 ft. Farther
west, moderate N winds and rough seas are occurring in the far
offshore waters of Guatemala due to the gale-force winds in the
Gulf of Tehuantepec. Meanwhile, moderate southerly winds and
moderate seas are found south of 05N. Elsewhere, light to gentle
winds and slight to moderate seas are prevalent.

For the forecast, fresh to strong NE winds and rough seas will
prevail in the Papagayo region through Sun. Rough seas in the
Guatemala offshore waters will dimish Sat as the Tehuantepec gap
event weakens. Moderate or lighter winds are forecast elsewhere
through the forecast period.

...REMAINDER OF THE AREA...

A subtropical ridge centered north of the remainder of the
tropical eastern Pacific and lower pressure in the deep tropics
support moderate to fresh easterly trade winds north of the
monsoon trough and ITCZ to 20N. Seas in these waters are 6-8 ft.
In the eastern waters, moderate to fresh easterly winds and seas
of 6-8 ft are noted north of 10N and east of 102W due to gap wind
event ongoing in Tehuantepec. South of the monsoon trough and ITCZ,
moderate to locally fresh southerly winds and moderate seas are
prevalent. Elsewhere, moderate or weaker winds and moderate seas
prevail.

For the forecast, moderate to locally fresh trade winds and
locally rough seas will persist in the western waters through
Sat. Meanwhile, a new set of NW swell with rough seas is
approaching the NW waters and will persist into weekend north of
25N with seas to 10 ft. Another large set of NW swell may arrive
to the NW waters by the end of the weekend and into early next
week.
