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 0000 UTC surface analysis and satellite imagery through
0305 UTC.

...SPECIAL FEATURES...

Hurricane Marie is centered near 20.8N 119.0W at 05/0300 UTC,
moving northwest at 7 kt. Estimated minimum central pressure is
967 mb. Maximum sustained wind speed is 85 kt with gusts to 105
kt. Peak seas are near 36 ft. Numerous moderate to isolated 
strong convection is present from 18N to 24N and between 115W and
121W. A general NW motion is expected to continue for the next 
few days. A gradual weakening trend is expected to begin on Saturday 
and continue for the next several days. Swells generated by Marie
will continue to affect portions of the coast of southwest 
Mexico, the Baja California Peninsula, and Southern California 
for the next few days. These swells are likely to cause life-
threatening surf and rip current conditions. Please consult 
products from your local weather office.

Hurricane Center at website - 
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml and the latest 
Marie NHC Forecast/Advisory and Public Advisory at 
www.hurricanes.gov for more details.

Hurricane Karina is centered west of the area near 20.7N 141.9W 
at 05/0300 UTC, moving west at 8 kt. Estimated minimum central 
pressure is 982 mb. Maximum sustained wind speed is 70 kt with 
gusts to 85 kt. While the center of Karina and most of the wind 
and wave impacts are west of 140W, strong to near-gale force 
winds along with rough to very rough seas are noted from 18N to 
27N and west of 135W. Most of the convective activity is now west
of 140W. Karina will continue to move away from the Eastern
Pacific waters during the next several days, allowing winds and 
seas east of 140W to subside through late Sat.

...TROPICAL WAVES...
 
A tropical wave is along 105W, extending from SW Mexico to 04N, 
moving west at 10-15 kt. A few showers are noted near the trough
axis.

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

The monsoon trough extends from 10N85W to 08N95W to 11N111W. 
Scattered moderate to isolated strong convection is occurring 
from 03N to 14N and east of 115W and from 08N to 15N and west of
115W.

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

Please see the Special Features section for information on 
Hurricane Marie centered southwest of Baja California, Mexico.

Moderate to fresh cyclonic winds and rough to very rough seas 
are affecting the offshore waters of Baja California not directly
impacted by Hurricane Marie. The pressure gradient between this 
hurricane and the ridge to the north support moderate southerly 
winds and slight seas in the northern Gulf of California. 
Elsewhere, primarily light to gentle winds and moderate seas 
prevail.

For the forecast, Hurricane Marie is near 20.8N 119.0W at 8 PM
PDT, and is moving northwest at 7 kt. Maximum sustained winds 
are 85 kt with gusts to 105 kt, and the minimum central pressure 
is 967 mb. Marie will move to 21.5N 119.9W Sat morning, 22.4N 
121.0W Sat evening, 23.2N 122.0W Sun morning, weaken to a 
tropical storm near 23.9N 122.8W Sun evening, 24.5N 123.8W Mon 
morning, and 25.2N 125.1W Mon evening. Marie will change little 
in intensity as it moves to the 27.4N 127.2W late Tue Elsewhere, 
moderate to fresh NW winds and moderate seas are expected in the
offshore waters of Baja California early next week. Looking 
ahead, the next gap wind event in the Gulf of Tehuantepec may 
occur by the middle of next week.

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

The subtropical ridge centered north of the Caribbean Sea forces
moderate to fresh easterly trade winds and moderate seas across
the Gulf of Papagayo region. Farther south, moderate to locally
fresh southerly winds and moderate seas are found south of 04N. 
Elsewhere, light to gentle winds and 2-4 ft seas prevail. 

For the forecast, a moderate pressure gradient across Central 
America will sustain fresh E winds over the Gulf of Papagayo into
early next week. Thereafter, the gradient may tighten and strong
gap winds and rough seas may develop. Moderate to locally fresh 
southerly winds are expected in the waters between Ecuador and 
the Galapagos Islands over the next several days, decreasing
slightly Sun and Mon. Elsewhere, moderate or lighter winds will 
prevail.

...REMAINDER OF THE AREA...

Please see the Special Features section for information about
Hurricane Karina centered west of 140W, and Hurricane Marie 
located southwest of Baja California, Mexico.

Away from the impacts of Hurricanes Karina and Marie, a cross
equatorial swell region is producing seas to 9 ft south of 07N
and between 91W and 114W. This was confirmed by a recent
altimeter pass. Elsewhere, moderate or weaker winds with seas 
5-7 ft are prevalent across the remainder of the tropical 
eastern Pacific.

For the forecast, Hurricane Marie is near 20.8N 119.0W at 8 PM
PDT, and is moving northwest at 7 kt. Maximum sustained winds 
are 85 kt with gusts to 105 kt, and the minimum central pressure 
is 967 mb. Marie will move to 21.5N 119.9W Sat morning, 22.4N 
121.0W Sat evening, 23.2N 122.0W Sun morning, weaken to a 
tropical storm near 23.9N 122.8W Sun evening, 24.5N 123.8W Mon 
morning, and 25.2N 125.1W Mon evening. Marie will change little 
in intensity as it moves to the 27.4N 127.2W late Tue.

The cross equatorial swell region west of the Galapagos Islands is
expected to diminish below 8 ft Sat night. Meanwhile, an area of
low pressure may develop well offshore of southwestern Mexico 
early next week. Gradual development is possible, and a tropical 
depression could form around the middle of next week while it 
moves west-northwestward at 10 to 15 mph, remaining well offshore
of Mexico. This system has a medium chance of tropical formation
over the next 7 days.
