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 1800 UTC surface analysis and satellite imagery through
2020 UTC.

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

A surface trough extends from Colombia near 10N75W to 04N82W to 
03N113W. The ITCZ extends from 03N113W to 05N134W to beyond 
07N140W. Scattered moderate convection is noted from 00N to 04N 
between 92W and 104W, and from 04N to 07.5N between 113W and 
133W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A surface ridge continues to extend from strong high pressure 
across the NE Pacific south and southeastward through 30N134W to
near 19N116W. Across the Baja offshore waters north of 21N, N 
winds are gentle to moderate, and seas are 4 to 6 ft in NW swell.
To the S of 21N, winds are light to gentle and seas are 3 to 5 
ft. Inside the Gulf of California, NNW winds continue to 
gradually diminish, and are gentle to moderate across central 
and southern portions, where seas are 3 to 5 ft.

Gentle to moderate winds are expected to 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 evening 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 and
produce a large area of seas 12 ft and higher extending well
offshore.

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

Moderate E winds prevail across the Papagayo region and extend
well offshore to near 92W. Gentle N to NE winds prevail across 
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 has settle southward during
the past 24 hours, and is now centered near 37N135W and analyzed
at 1031 mb. A broad ridge extends southward 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 118W, with gentle to moderate N to NE winds to the 
N. Seas are 8 to 10 ft in mixed swell across the trade wind 
zone, and 5 to 8 ft elsewhere W of 118W. 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 125W 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.
