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 1800 UTC surface analysis and satellite imagery through
2030 UTC.

...TROPICAL WAVES...

A tropical wave is along 93W north of 04N, moving westward at 
10-15 kt. Scattered showers are noted along the wave axis.

A tropical wave is near 125W from 04N to 20N, moving westward at
10-15 kt. Scattered showers are noted along the wave axis.

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

The monsoon trough extends from 10N85W to 10N140W. Scattered 
moderate convection is active within 270 nm on either side of the
trough.
 
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface ridge north of 20N is maintaining moderate NW winds 
off Baja California, with light to gentle breezes elsewhere over 
Mexican offshore waters. Combined seas are 3 to 5 ft in open 
waters, and 1 to 3 ft over the Gulf of California.

For the forecast, a surface ridge will continue to dominate the
offshore forecast waters of Baja California through the middle
of the week, with little change in winds and seas. 

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

Scattered moderate convection prevails across portions of Costa
Rica and Panama due to the monsoon trough extending across the
area. In the Papagayo region, moderate NE winds and moderate 
seas prevail. Light to gentle winds prevail elsewhere across the 
area north of the monsoon trough with slight to moderate seas. 
South of the monsoon trough, moderate to fresh S to SW winds are 
ongoing with moderate seas to 7 ft, highest east of the Galapagos
Islands.

For the forecast, gentle to moderate winds and moderate seas 
will persist across the region into mid week.

...REMAINDER OF THE AREA...

A surface ridge dominates most of the waters north of 20N and 
west of 115W. Fresh NE winds and seas to 9 ft are noted from 10N
to 20N and west of 135W, while gentle to moderate anticyclonic 
flow and 5-7 ft seas prevail elsewhere. Moderate to fresh 
southerly winds are noted south of the monsoon trough. 
 
For the forecast, the surface ridge will continue to build 
across most of the forecast waters north of 15N and west of 110W 
through the next few days. Elsewhere, southerly winds south of 
the monsoon trough to the Equator will remain moderate through 
the week, with seas of 5 to 7 ft primarily in southerly swell.
