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 0600 UTC surface analysis and satellite imagery through
0830 UTC.

...TROPICAL WAVES...

A tropical wave is analyzed along 84W to the north of 06N, 
moving westward at 10-15 kt. Any nearby convection is described 
in the monsoon trough/ITCZ section below.

A new tropical wave is analyzed along 107W, from 02N to 16N,
moving westward at 10-15 kt. Any nearby convection is described 
in the monsoon trough/ITCZ section below.

A tropical wave is analyzed along 131W from 02N to 16N, moving 
westward at around 10-15 kt. Any nearby convection is described 
in the monsoon trough/ITCZ section below.
 
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough axis extends from 09N78W to 09N85W to 07N90W.
The ITCZ extends from 07N90W to 07N105W, from 07N109W to 09N130W,  
and from 08N135W to 07N140W. Scattered moderate convection is 
active from 05N to 15N between 95W and 105W, from 05N to 10N 
between 115W and 125W, and from 08N to 12N between 130W and 140W.

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

Fresh to locally strong NW winds and 6-7 ft seas are observed in
recent satellite data 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 Gulf of Tehuantepec, with 5-7 ft seas. Gentle 
to moderate breezes and 4-6 ft seas are noted elsewhere, except 
1-3 ft seas across the Gulf of California. Thunderstorms are 
active inland from Jalisco to Sonora, and gusty winds may be 
occurring near the coast.

For the forecast, the ridging will persist off Baja California through mid
week, with lower pressure inland over northwest Mexico. This
pattern will support fresh to occasionally strong NW winds off
Baja California Norte through tonight, with rough seas in NW 
swell near Guadalupe Island into Thu. The 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. Looking ahead, lowering 
pressure across the tropical eastern Pacific will induce fresh to
strong winds and occasionally rough seas offshore southern 
Mexico by the weekend.

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

A recent scatterometer satellite pass indicated a pulse of fresh
to strong NE to E gap winds persist across the Papagayo region 
and Nicaragua, extending offshore to near 90W. Seas are estimated
to be 6-9 ft. Moderate to locally fresh winds are elsewhere to 
the N of 08N. Moderate N to NE winds are in the Gulf of Panama 
downwind to near 07N, with 4-6 ft seas. 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 
Wed, with seas peaking around 9 ft. Gentle to moderate breezes 
and slight to moderate seas will persist elsewhere. Looking 
ahead, lowering pressure across the tropical eastern Pacific will
induce fresh to strong winds and occasionally rough seas 
offshore El Salvador and Guatemala by Sun.  

...REMAINDER OF THE AREA...

A trough, the remnant of Douglas, is along 137W/138W from 23N to
29N. 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 ahead of the tropical wave near 131W, specifically from 10N to 
20N between 130W and 140W. 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 131W at it moves westward at 10-15 kt, 
reaching 135W by tonight, and 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.
