...SPECIAL FEATURES...

Hurricane Genevieve is centered near 19.6N 120.8W at 30/0300
UTC, moving west-northwest at 8 kt. Estimated minimum central
pressure is 970 mb. Maximum sustained wind speed is 85 kt with
gusts to 105 kt. Peak seas are near 35 ft or 10.5 m. Numerous
moderate convection is within 150 nm of the center. Genevieve is
moving toward the west-northwest. This general motion with a 
slight increase in forward speed is expected during the next 
several days. Steady 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

...TROPICAL WAVES...

A tropical wave is along 94W, extending from just NW of the
Galapagos Islands to the Guatemala-Mexico border, moving west at
15 to 20 kt. Scattered moderate convection is noted from 10N to
13N between 93W and 96W. 

A tropical wave is along 109W, from 03N to 18N, drifting W at
around 5 kt. Scattered moderate convection is noted from 10N to
18N between 102W and 112W. 

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

The monsoon trough extends from 10N80W to 09N89W to 09N104W to
14N114W. The ITCZ extends from 11N123W to beyond 08N140W. 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 sections above for 
information about convection in the region.

Hurricane Genevieve is well west of the Revillagigedo Islands 
moving away from the region. Associated rough seas impacting the
far western offshore waters of Baja California will subside Thu. 
Elsewhere, moderate or weaker winds prevail. Seas are slight in 
the Gulf of California and moderate in the remaining offshore 
waters.

For the forecast, fresh northerly winds are likely in the Gulf 
of Tehunatepec Thu and Fri nights. Elsewhere, areas of fresh 
mainly westerly gap winds are expected through Thu night 
nearshore Baja California as high pressure builds southward to 
the west of the Baja California Peninsula. Moderate to locally 
fresh SE to S winds may pulse in the northern Gulf of California 
beginning this weekend. Looking ahead, rough northerly seas may 
briefly build south of 30N into the waters off Baja California 
Norte by the end of the weekend into early next week. 

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

Please refer to the Tropical Wave sections above for information
about convection in the region. 

High pressure northeast of the area is forcing fresh to strong 
easterly gap winds and resultant seas of 5 to 7 ft across the 
Gulf of Papagayo region, with moderate to locally fresh northerly
gap winds in the Gulf of Panama. 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 from offshore southern California SW to about
12N140W. 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 the the remaining waters away from Genevieve.

Hurricane Genevieve is near 19.6N 120.8W at 8 PM PDT, and is 
moving west-northwest at 8 kt. Maximum sustained winds are 85 kt 
with gusts to 105 kt, and the minimum central pressure is 970 mb.
For the forecast, Genevieve will move to 20.1N 122.6W Thu 
morning, 20.8N 125.0W Thu evening, then weaken to a tropical 
storm near 21.6N 127.5W Fri morning. Tropical Storm Genevieve 
22.3N 130.3W Fri evening, 23.1N 133.0W Sat morning, and 23.9N 
135.9W Sat evening. Genevieve will become post-tropical as it 
moves into the Central Pacific basin late Sun.

Away from Genevieve, little change in marine conditions is 
forecast into the weekend. Fresh and rough northerly swell off 
California may 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.
