from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.
Based on 0000 UTC surface analysis and satellite imagery through
0200 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends from 08N84W to 06N104W. The ITCZ
continues from 06N104W to 06N115W. Another surface trough
extends from 09N117W to 04N120W. The ITCZ resumes from 04N121W to
03N140W. Scattered moderate convection is noted from 02N to 07N
and E of 95W, and from 02N to 09N between 110W and 125W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Moderate 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 7 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 6 ft. Light to gentle winds and moderate seas of 3 to 5 ft
in SW swell are noted elsewhere.
For the forecast, mainly gentle 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 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 130W due to fresh trade winds and
lingering swell into early next week. A weak frontal boundary
will approach the far NW waters Fri then dissipate over the
weekend.
