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.
 
...SPECIAL FEATURES...

Hurricane Genevieve is centered near 20.2N 122.1W at 30/0900
UTC, moving west-northwest at 10 kt. Estimated minimum central
pressure is 973 mb. Maximum sustained wind speed is 80 kt with
gusts to 100 kt. Peak seas are near 34 ft or 10.5 m. Numerous
moderate convection is within 150 nm in the NE semicircle and 30
nm in the SW semicircle. Genevieve is moving toward the west-
northwest. This general motion with a slight increase in forward 
speed is expected during the next several days. Gradual 
weakening is expected during the next couple of days, and 
Genevieve is forecast to become post-tropical this weekend. 
Swells generated by Genevieve are affecting portions of the Baja 
California Peninsula and Southern California. These swells will 
persist for the next several days, and are likely to cause life-
threatening surf and rip current conditions. Please consult 
products from your local weather office. Please read the latest 
HIGH SEAS FORECAST issued by the National Hurricane Center at 
website - https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml and the 
latest Genevieve NHC Forecast/Advisory and Public Advisory at 
www.hurricanes.gov for more details.

...TROPICAL WAVES...

A tropical wave is along 96W, extending from 02N to the Gulf of
Tehuantepec, moving W at around 15 kt. Scattered moderate 
convection is noted from 07N to 14N between 93W and 102W. 

A tropical wave is along 109W, from 03N to 18N, drifting W at
less than 5 kt. Scattered moderate to isolated strong convection
is noted from 09N to 18N between 102W and 112W. 

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

The monsoon trough extends from 10N82W to 09N96W to 13N114W.  
Nearby convection is primarily associated with the tropical waves
described in the above section.

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

Please refer to the Tropical Waves section above for information
about convection in the region.

Swells from Hurricane Genevieve, centered well W of the area and
moving away, are still bringing some rough seas to about 10 ft to
the outer offshore waters of Baja California Sur. Scattered
convection, likely inducing locally gusty winds, has moved off
the Sinaloan coast into the southern Gulf of California and
adjacent waters to the south. Locally fresh N gap winds have
developed in the Gulf of Tehuantepec. Elsewhere, moderate or 
weaker winds prevail. Seas are slight in the Gulf of California 
and moderate in the remaining offshore waters.

For the forecast, rough seas in the outer offshore waters W of 
Baja California will diminish today. Increasing NW swell may lead
to rough seas again offshore Baja California Norte Sun night and
Mon. Fresh to locally strong gap winds are likely in the Gulf of
Tehuantepec late tonight and are possible again Fri night. 
Moderate to fresh NW winds are expected to pulse tonight and Fri 
night nearshore Baja California as high pressure builds southward
W of the Peninsula. Elsewhere, Fresh SE to S winds may pulse 
nightly in the northern Gulf of California beginning Sat night.

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

Please refer to the Tropical Waves section above for information
about convection in the region. 

High pressure northeast of the area is forcing strong easterly 
gap winds and resultant seas of 7 to 9 ft across the Gulf of 
Papagayo region, with moderate to fresh northerly gap winds and 5
to 7 ft seas in the Gulf of Panama. Scattered moderate 
thunderstorms have moved offshore northern Colombia, likely 
accompanied by locally higher winds and waves. Elsewhere, light 
to gentle winds and moderate seas prevail. 

For the forecast, fresh to strong NE to E gap winds will pulse 
across the Papagayo region through Sun, with occasionally rough 
seas. Pulsing moderate to locally fresh N winds are expected in 
the Gulf of Panama tonight and Thu night. Southerly winds may 
freshen offshore southern Colombia and from Ecuador to the 
Galapagos Islands Thu night and Fri. Moderate or weaker winds and
moderate seas in SW swell are expected across the remainder of 
the waters through the period. 

...REMAINDER OF THE AREA...

Please refer to the Special Features section for information on
Hurricane Genevieve.

For waters not being impacted by Hurricane Genevieve, high
pressure is centered just northwest of the area. The pressure 
pattern between the high and Genevieve is supporting moderate to 
fresh NE trades to the north and west of Genevieve. Seas in this
region have built to 6 to 9 ft. Moderate to locally fresh SE 
winds are found south of the Equator and west of 100W. Moderate 
or weaker winds are elsewhere. Moderate seas dominate waters S of
13N.

Hurricane Genevieve is near 20.2N 122.1W at 2 AM PDT, and is
moving west-northwest at 10 kt. Maximum sustained winds are 80
kt with gusts to 100 kt, and the minimum central pressure is 973
mb. Genevieve will move to 20.7N 123.9W this afternoon, 21.5N
126.5W Fri morning, then weaken to a tropical storm near 22.1N 
129.1W Fri afternoon. Tropical Storm Genevieve will be near 
22.9N 131.8W Sat morning, 23.8N 135.0W Sat afternoon, and 24.5N 
138.0W Sun morning. Genevieve will weaken to a remnant low as it
moves into the Central Pacific basin early Mon.

Away from Genevieve, little change in marine conditions is 
forecast through the weekend. Fresh and rough northerly swell 
off California is likely to push southward into the waters off 
Baja California Norte north of 27N and east of 130W by the end of
the weekend into early next week.
