Tropical Weather Discussion

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
2030 UTC.

...TROPICAL WAVES...

A tropical wave is analyzed along 86W to the north of 04N, 
moving westward at 10-15 kt. No significant convection is noted
at this time.

A tropical wave is analyzed along 109W, from 03N to 16N, moving 
westward at 10-15 kt. Scattered moderate convection is noted 
along the wave axis S of 13N.

A tropical wave is analyzed along 135W from 02N to 16N, moving 
westward at around 10-15 kt. Scattered moderate convection is 
noted from 10N to 14N between 131W and 138W.
 
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough extends from 08N78W to 04N124W. The ITCZ is 
from that point to 05N131W. Scattered moderate convection is 
active within 90 nm S of the monsoon trough and E of 83W, and
within 300 nm on either side of the boundaries and W of 94W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Fresh NW winds and 6-7 ft seas prevail off Baja California Norte
between high pressure west of the area and lower pressure over 
northwest Mexico. Farther south, fresh to strong N to NE gap 
winds are active across the Tehuantepec region, with 6-8 ft seas.
Gentle to moderate breezes and 4-6 ft seas are noted elsewhere, 
except 1-4 ft seas across the Gulf of California. 

For the forecast, fresh NW winds off Baja California Norte 
through tonight, with rough seas in NW swell near Guadalupe 
Island into Thu. These winds will diminish Thu, as low pressure 
moves off the Pacific into the lower Colorado River Valley. This 
will result in fresh to strong S winds and rough seas late Thu 
into Fri over the Gulf of California. Fresh to strong northerly 
gap winds will pulse in the Gulf of Tehuantepec through the week.
Lowering pressure across the tropical eastern Pacific will 
induce fresh to strong winds and rough seas offshore southern 
Mexico by the weekend.

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

Fresh NE to E gap winds persist across the Papagayo region and 
Nicaragua, extending offshore to near 90W. Seas are estimated to 
be 6-8 ft. Moderate to fresh winds are elsewhere to the N of 
08N. Gentle N to NE winds are in the Gulf of Panama downwind to 
near 07N, with seas to 5 ft. Moderate SE winds are across the 
offshore waters of the Galapagos Islands, where seas are 5-7 ft 
in SW swell. Light to gentle winds are across the remainder of 
the waters, along with 4-6 ft mainly in SW swell.

For the forecast, fresh to strong NE-E gap winds will pulse in the
Gulf of Papagayo region through late Sun, mainly at night and
into the morning hours. Cross equatorial SW swell will move 
through the waters off Ecuador and the Galapagos Islands
through tonight, with seas peaking around 9 ft. Gentle to 
moderate breezes and slight to moderate seas will persist 
elsewhere. Lowering pressure across the tropical eastern Pacific
will induce fresh to strong winds and rough seas offshore El 
Salvador and Guatemala by Sun. 

...REMAINDER OF THE AREA...

A surface trough, the remnant of Douglas, is along 140W from 24N
to 30N. Elsewhere, a broad ridge dominates the waters north of 
15N, supporting moderate NE winds and 5-7 ft seas in a mix of N 
and SW swell. Fresh NE winds and seas 7-8 ft are also noted 
farther S near the tropical wave near 135W. Gentle to moderate 
breezes are noted elsewhere. Long period SW swell to 8 ft is 
reaching 05N between 90W and 120W. Combined seas are mainly 5-7 
ft elsewhere.

For the forecast, strong winds and rough seas will accompany the
tropical wave near 135W at it moves westward at 10-15 kt, past 
140W by late Fri. Farther N, swell of 8-9 ft will persist north 
of 25N to the E of 125W through Fri. Farther S, large swell to 
7-8 ft will persist south of 05N or so between 95W and 120W 
through Fri.
