information is based on satellite imagery, weather observations,
radar, and meteorological analysis.
Based on 1800 UTC surface analysis and satellite imagery through
2000 UTC.
...TROPICAL WAVES...

west at around 10 kt. Scattered moderate and isolated strong
convection is noted from 04N-08N between 87W-95W.
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 07N-17N between 101W-109W.
The axis of a tropical wave is near 117W from 07N-15N, moving
westward at around 10 kt. Scattered moderate and isolated strong
convection is noted from 07N-15N between 118W-125W.
The axis of a tropical wave is near 128W from 05N-14N, moving
westward at around 10 kt. Scattered moderate and isolated strong
convection is noted from 09N-13N between 125W-129W.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough extends from coastal Panama near 08N78W to
10N124W. The ITCZ continues from 10N130W to 09N140W. Scattered
moderate and isolated strong convection is noted from north of
04N east of 83W, 04N-08N between 87W-95W, from 07N-17N between
101W-109W, from 07N-15N between 118W-125W, from 09N-13N between
125W-129W, and from 05N-12N west of 135W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Fresh N gap winds over the Gulf of Tehuantepec with seas 6-7 ft
are occurring this afternoon. Fresh to strong SE winds over the
N and central Gulf of California with seas 3-6 ft exist.
Elsewhere winds are gentle to moderate with seas 4-6 ft in mixed
swell over forecast waters.
For the forecast, a low pressure system over the SW United
States will maintain the 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 SE to SW winds are found
south of the monsoon trough. Seas are 5-7 ft in S to SW swell.
For the forecast, the 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 for the next few days. Moderate SW swell currently
impacting the equatorial zones should diminish on Sat. Looking
ahead, a resumption of the fresh E gap winds over the Gulf of
Papagayo region may occur starting Mon night.
...REMAINDER OF THE AREA...
A 1034 mb high is centered at 39N141W with a surface ridge
extending to 30N125W to 19N110W. 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 afternoon, before being enhanced again
starting Sat night.
