Corrected Remainder of the Area section

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 
1545 UTC.

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

The monsoon trough extends from 15N95W to 10N115W to 09N130W. 
The ITCZ extends from 09N130W to beyond 06N140W. Scattered 
moderate convection is seen within 180 nm south of the trough 
between 97W and 101W, within 60 nm south of the trough between 
115W and 120W and within 30 nm of the ITCZ between 136W and 140W.

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

An overnight altimeter satellite pass indicated seas of 8 to 10 
ft offshore of Oaxaca in southern Mexico, beyond 90 nm from the 
coast. These combined seas are mostly due to long-period 
southwest swell lingering from southwest fresh to strong winds 
of the past few days. Deep-layer moisture remains abundant over 
the area, supporting scattered showers and thunderstorms along 
the coasts of the states of Guerrero and northern Michoacan. 
This activity reaches offshore for about 120 nm.

Scattered moderate to isolated strong that moved offshore 
Mexican coast during the overnight hours is weakening as it 
moves northwestward just offshore the coast between 17N and 
Manzanillo extending offshore for about 120 nm.

For the forecast, winds and seas will continue to improve today 
off the southern Mexico offshore waters. To the north, fresh 
northwest winds and rough seas are expected over the Baja 
California offshore waters through tonight. Conditions across 
the Mexico offshore waters will improve through the early part 
of next week. 

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

The broad low pressure over northern Central America has 
weakened and shifted northward, allowing winds and seas to 
diminish across the region. Seas to 8 ft persist in the offshore 
waters of Guatemala beyond 90 nm, associated with lingering SW 
swell caused by persistent fresh to strong SW winds. Elsewhere, 
gentle to moderate winds and mostly moderate combined seas 
persists. 

For the forecast, seas to 8 ft will linger off Guatemala today, 
then subside. Gentle to moderate winds and slight to moderate 
wave heights will persist elsewhere across the region through 
the early part of next week.

...REMAINDER OF THE AREA...Corrected

A broad surface ridge extends from strong high pressure of 1029 
mb that is located well NW of the area near 35N154W, 
southeastward to the Baja California offshore waters. The 
associated gradient is supporting generally gentle to moderate 
north to northeast winds west of about 110W, except for slightly 
higher fresh northeast winds north of 22N west of 137W as seen 
in overnight ASCAT satellite data passes over that part of the 
area. Seas with these winds are in the range of 4 to 6 ft, 
except for slightly higher seas of 5 to 7 ft north of 22N west 
of 137W. Gentle to moderate east to southeast winds are south of 
04N between 83W and 100W, and mostly gentle south to southwest 
winds are elsewhere south of the monsoon trough and mostly 
gentle east to southeast are south of the ITCZ. Seas with these 
winds are 5 to 7 ft, except for seas of 7 to 9 ft in long-period 
southwest swell south of the monsoon trough to 07N between 95W 
and 107W. 

For the forecast, monsoonal winds and seas east of 110W and 
north of 05N will gradually decrease today. Otherwise, little 
overall changes are expected through early next week.
