Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
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 1200 UTC surface analysis and satellite imagery through
1520 UTC.

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

A surface trough extends from Colombia near 10N75W to 04N83W to 
03N113W. The ITCZ extends from 03N113W to 05N134W to beyond 
06.5N140W. Scattered moderate convection is noted from 00N to 03N
between 91.5W and 103W, and from 04N to 09N between 115W and
136W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A surface ridge extends from strong high pressure across the NE 
Pacific south and southeastward through 30N133W to near 24N117W.
Across the Baja offshore waters north of 22N, N winds are gentle
to moderate, and seas are 4 to 6 ft in NW swell. To the S of 
22N, winds are light to gentle and seas are 3 to 6 ft. Inside 
the Gulf of California, NNW winds continue to gradually 
diminish, and are moderate across central and southern portions,
where seas of 4 to 6 ft persist.

Gentle to moderate winds will prevail area wide into late week. 
A weak cold front will move down the Gulf of California Thu
afternoon through Thu night and bring strong winds to the Gulf 
behind it Thu night into Sat. Seas will build to 8 ft and higher. 
Looking ahead, strong gales will develop in the Gulf of 
Tehuantepec Sat and continue through the weekend.

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

Moderate to locally fresh E winds are noted across the Papagayo 
region, with moderate N to NE winds in the Gulf of Panama. 
Elsewhere, winds are light to gentle with seas of 3 to 5 ft.

Gap winds across the Papagayo region will diminish into tonight.
N to NE winds in the Gulf of Panama will become light to gentle 
the remainder of the week. Mainly gentle winds will prevail 
elsewhere. Fresh to strong gap winds will return to Papagayo Sun 
evening. 

REMAINDER OF THE AREA

High pressure across the NE Pacific is sinking southward and
weakening. The latest surface analysis shows a 1031 mb high 
now centered near 39N136W with a broad ridge extending south
between 115W and 145W. The pressure gradient south of the ridge
is supporting widespread mainly fresh NE to E winds between the 
ITCZ and 20N, to the W of 120W, with gentle to moderate Nto NE 
winds to the N. Seas are 8 to 11 ft in mixed swell across the
trade wind zone, and 6 to 8 ft elsewehre W of 120W. To the S of 
the ITCZ, gentle to moderate E to SE winds prevail with seas of 5
to 7 ft.

The pressure gradient S of 25N and W of 122W will support fresh 
trades and seas of 8 to 10 ft most of the week. Winds and seas 
will diminish by the weekend as a cold front approaches far NW 
portions of the discussion area.
