Corrected Offshore Waters Within 250 nm of Mexico 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
2145 UTC.

...SPECIAL FEATURES...

Post-Tropical Cyclone Flossie Gale Warning: The remnant low of 
of recent Tropical Storm Flossie is centered near 21N112W, or 
about 175 nm southwest of Cabo San Lucas, Mexico at 2100 UTC 
with a pressure of 1003 mb. It is moving northwestward at 9 kt. 
A recent scatterometer satellite data pass depicts gale-force 
winds of 30 to 35 kt within 60 nm of the low within 60 nm in 
the E semicircle and within 30 nm of the low in the NW quadrant.
Seas are 10 to 14 ft within about 60 nm of the center in the 
northern semicircle and 8 to 12 ft elsewhere within 120 nm of 
the center. Latest satellite imagery depicts the low as a 
swirl of low to mid-level type clouds covering the area from 
18N to 23N between 110W and 116W. satellite imagery shows that 
deep convection of the scattered moderate to isolated strong-
type intensity has recently formed within 60 nm of the low in 
the W quadrant. Scattered showers may be possible elsewhere 
underneath the observed clouds. The low is forecast to gradually 
weaken as it reaches near 22N114W late tonight, with winds 
easing to just below gale-force. Seas are forecast to subside to 
just below 12 ft at that time. Please read the latest High Seas 
Forecast issued by the National Hurricane Center at website 
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for further 
details. 

South of Southern Mexico:
A large area of disorganized showers and thunderstorms, partly
associated with a tropical wave that is along 97W as described
below is centered a few hundred miles south of southern Mexico.
Gradual development of this system is expected during the next
few days, and a tropical depression is likely to form over the
weekend or early next week while it moves generally west-
northwestward well off the coast of Mexico. This system has a
medium chance of tropical cyclone development during the next 48
hours. Please refer to the latest NHC Tropical Weather Outlook at
wwww.hurricanes.gov for more details.

...TROPICAL WAVES...

A tropical wave has its axis along 97W from 04N to 17N. Scattered 
moderate convection is within 60 nm either side of the wave
from 10N to 14N. 
 
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough axis extends from low pressure that is along 
northwest Colombia westward through southern Costa Rica to 
09N84W to 09N94W to 14N106W to 11N113W to 10N120W to 07N128W,
where it transitions to the ITCZ and continues to 07N137W and to
beyond 08N140W. Numerous moderate to strong convection is 
within 150 nm either side of the trough between 101W-105W. 
Scattered moderate convection is within 120 nm south of the 
trough between 110W-118W.

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

Please refer to the Special Features section above for details 
on a Gale Warning issued for Post-Tropical Cyclone Flossie, and 
on an upcoming tropical system.

Aside from the gale conditions associated to Post-Tropical 
Cyclone Flossie, the gradient related to high pressure over the 
offshore waters of Baja California is maintaining generally 
gentle to moderate northwest to north winds over these waters. 
Seas over these waters are 5 to 7 ft. The latest scatterometer 
satellite data pass indicated a patch of fresh to strong
southeast to south winds over the southern section of the 
Gulf of California. Moderate to fresh southerly winds are over 
the northern section of the Gulf and over a section of the 
central Gulf. Seas are in the range of 3 to 5 ft, except for 
higher seas of 5 to 7 ft at the entrance to the Gulf and over the
extreme southern part of the Gulf.

For the forecast, the Post-Tropical Cyclone Flossie low pressure
is forecast to gradually weaken as it reaches near 22N114W late 
tonight, with winds easing to just below gale-force and seas
lowering to just below 12 ft. Elsewhere, swell generated by 
Flossie will continue to affect portions of the coast of 
southwestern Mexico and the Baja California peninsula for another
day or so. Winds over the central part of the Gulf of California
are forecast to increase to fresh to strong speeds tonight while
similar winds continue over the southern section of the Gulf 
into Fri morning. Looking ahead, fresh, to at times, strong east 
to southeast winds and rough seas are possible off Oaxaca and 
Guerrero tonight through Fri as an area of low pressure moves to 
the west-northwestward and offshore of the coast of southern 
Mexico. This area of low pressure is the one described above 
under the Special Features section. 

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

Latest scatterometer satellite data passes indicate that moderate 
to fresh east to southeast winds are present to the southwest of 
Guatemala in the wake of the tropical wave this is along 97W 
from 10N to 12N between 93W and 97W. Seas are 6 to 8 ft with 
these winds. Fresh northeast to east winds are in the Gulf of 
Papagayo region. Meanwhile, gentle to moderate southerly winds 
and moderate seas are occurring south of 04N. Elsewhere, light 
to gentle winds and moderate seas prevail.

For the forecast, the fresh northeast to east winds in the 
Gulf of Papagayo region will diminish Fri afternoon as the
tropical wave along 97W continues westward away from the region.
Elsewhere, gentle to moderate winds and moderate seas in 
southerly swell are expected. Moderate to large cross-equatorial 
south to southwest swell will begin to propagate through the 
waters southwest of the Galapagos Islands starting Fri.
Moderate or weaker winds are forecast across the entire region 
over the weekend. 

...REMAINDER OF THE AREA...

Broad high pressure over this part of the region supports 
moderate to locally fresh north to northeast winds north of 20N,
along with seas of 6 to 8 ft. Cross-equatorial swell producing 
seas to 9 ft is expected to begin propagating through the 
waters south of about 01N between 102W and 115W starting 
tonight, with little change through Sat. Expect for increasing 
winds and seas over the far eastern part of the area during the 
next few days resulting from the Special Features area of 
disorganized showers and thunderstorms that is expected to 
undergo gradual development leading to a tropical depression late
this weekend or early next week as it generally tracks west- 
northwestward well off the coast of Mexico.
