information is based on satellite imagery, weather observations,
radar, and meteorological analysis.

Based on 1200 UTC surface analysis and satellite imagery through
1500 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is near 87W north of 08N, moving
west at around 10 kt. Scattered moderate and isolated strong
convection is noted from 04N-09N east of 90W.

The axis of a tropical wave is near 106W north of 08N, moving
westward at around 10 kt. Scattered moderate and isolated strong
convection is noted from 06N-16N between 100W-107W.

The axis of a tropical wave is near 116W from 07N-17N, moving
westward at around 10 kt. Scattered moderate and isolated strong
convection is noted from 07N-13N between 114W-120W.

The axis of a tropical wave is near 127W from 04N-15N, moving
westward at around 10 kt. Scattered moderate and isolated strong
convection is noted from 05N-13N between 120W-128W.

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

The monsoon trough extends from coastal Costa Rica near 10N86W
to 10N110W. The ITCZ continues from 10N110W to 10N115W, from
09N117W to 08N126W, and from 08N128W to beyond 06N140W.
Scattered moderate and isolated strong convection is noted from
04N-09N east of 90W, from 06N-16N between 100W-107W, from 07N-13N
between 114W-120W, from 05N-13N between 120W-128W, and from
05N-11N west of 135W.

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

Fresh to locally strong N gap winds over the Gulf of Tehuantepec
with seas 6-7 ft. Fresh to strong SE winds over the N and
central Gulf of California with seas 3-4 ft are occurring this
morning. Elsewhere winds are gentle to moderate with seas 4-6 ft
in mixed swell.

For the forecast, the fresh to locally strong N gap winds over
the Gulf of Tehuantepec will diminish this evening. Low pressure
over the SW United States will maintain fresh to strong SE winds
over the N and central Gulf of California through Sat morning.
Mainly gentle to moderate winds will prevail elsewhere through
early next week.

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

Gentle to moderate NE to E winds are occurring north of the
monsoon trough and gentle to moderate S to SW winds are found
south of the monsoon trough. Seas are 5-6 ft in S to SW swell.

For the forecast, moderate to fresh E gap winds will continue
across the Gulf of Papagayo region through Sat morning. Gentle to
moderate winds will prevail elsewhere over forecast waters.
Elsewhere, light to gentle winds will prevail. Moderate SW swell
currently impacting the equatorial zones should diminish on Sat.

...REMAINDER OF THE AREA...

A 1033 mb high is centered at 39N141W with a surface ridge
extending to 30N127W to 20N110W. The moderate pressure gradient
between the ridge and lower pressure over the ITCZ/monsoon trough
is producing only moderate to locally fresh winds across forecast
waters. south of 02N and west of 100W, seas are 8-10 ft in SE to
S swell. Elsewhere, seas are 5-7 ft in mixed swell.

For the forecast, little change to winds and wind waves are
expected for the next few days. The large SE to S swell will
diminish some by Fri night, before being enhanced again starting
Sun.
