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
2000 UTC.

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

The monsoon trough extends from 08N78W to 08N84W to 06N90W. The 
ITCZ extends from 06N90W to 04N140W. Scattered moderate 
convection is noted from 04N to 08N between 94W and 111W, and 
from 03N to 09N between 132W and 140W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Strong to near- gale force winds, and seas to 11 ft prevail over
the Gulf of Tehuantepec. Gentle to moderate winds are noted off 
Baja California Norte, as well as the northern Gulf of
California. Light to gentle winds are noted elsewhere. Seas are 
in the 5-7 ft range over the open waters off Mexico, and 1-3 ft 
over the Gulf of California. 

For the forecast, strong to near-gale winds in the Gulf of 
Tehuantepec will diminish this weekend. A cold front will move 
across the Baja California Norte region enhancing winds and seas 
N of Punta Eugenia late this weekend through early next week.

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

Strong to near gale force NE-E gap winds prevail across the Gulf
of Papagayo region and Nicaragua offshore waters along with seas
of 8 to 11 ft. The strong winds reach as far west as 95W. 
Moderate to locally strong winds and seas of 8-10 ft associated 
with both the Papagayo and Tehuantepec gap wind events are 
affecting the Guatemala and El Salvador offshore waters. Fresh to
strong N to NE winds, and seas to 8 ft, are across the Gulf of 
Panama. Elsewhere, light to gentle winds and seas to 6 ft in SW 
swell prevail.

For the forecast, strong to occasionally near gale force NE 
winds over the Gulf of Papagayo region will prevail through the 
middle of next week. Strong N to NE winds in the Gulf of Panama 
will diminish to fresh speeds Sun evening and to moderate speeds 
Thu. Swell generated from the gale force gap wind event in the 
Gulf of Tehuantepec across the El Salvador and Guatemala offshore
waters will subside this weekend. 

REMAINDER OF THE AREA...

Surface ridging prevails across the waters of 20N. The pressure
gradient between this area of high pressure and lower pressure in
the vicinity of the ITCZ is supporting moderate to fresh winds N
of the ITCZ to 22N and W of 125W. Seas over this area are in the
8-9 ft range in a mix of NW swell and NE wind waves. Gentle to 
moderate winds and seas of 6-7 ft prevail elsewhere across the 
discussion waters.

For the forecast, NW swell will slowly subside through the 
weekend. A new set of NW swell propagate into the waters south 
of 30N Sun night into Mon. The moderate to fresh tradewinds will
continue through the middle of next week.
