...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends from 09N84W to 07N102W. The ITCZ
continues from 07N102W to 08N118W. Another surface trough
extends from 10N120W to 05N120W. The ITCZ resumes from 05N123W
to 03N140W. Scattered moderate convection is noted S of 07N and
E of 88W, and from 04N to 10N between 110W and 124W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Moderate to fresh NW winds persist along the coast and offshore
waters of Baja California, between weak high pressure west of the
area and lower pressure over central Mexico. NW swell moving
through the regional waters is producing seas of 5 to 6 ft to the
Revillagigedo Islands while gradually subsiding. Gentle winds
and moderate seas persist elsewhere.
For the forecast, gentle to moderate winds winds and moderate
seas will persist through Sat. Looking ahead, fresh NW winds and
building swell will follow a weak cold front into the waters near
Guadalupe Island off Baja California Norte Sun and Mon.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR
Moderate N gap winds persist in the Gulf of Panama, with seas of
4 to 5 ft. Moderate S winds and seas to 6 ft prevail across the
waters W of Ecuador. Light to gentle winds and moderate seas in
SW swell are noted elsewhere.
For the forecast, gentle to moderate breezes will persist across
the region into early next week. Wave heights will be mostly 4
to 6 ft primarily in SW swell, building to 5 to 7 ft off Ecuador
Sat night.
...REMAINDER OF THE AREA...
Broad surface ridging persists N of 10N, supporting moderate to
fresh trade winds across the tropical Pacific W of 120W. Combined
seas are 8 to 9 ft in this area, in mainly shorter-period
easterly waves resulting from the trade wind flow. Light to
gentle breezes and moderate seas are evident elsewhere.
For the forecast, wave heights will slowly subside across the
region into the weekend, although an area of 8 ft seas will
persist from 08N to 12N W of 135W due to fresh trade winds and
lingering swell into early next week. A weak frontal boundary
will enter the far NW waters today then dissipate over the
weekend.
