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
1300 UTC.
 
...SPECIAL FEATURES...

Hurricane Genevieve is centered near 18.8N 119.2W at 29/1500
UTC, moving west-northwest at 7 kt. Estimated minimum central
pressure is 960 mb. Maximum sustained wind speed is 100 kt with
gusts to 120 kt. Peak seas are near 37 to 38 ft, or 11 m. 
Numerous moderate isolated strong convection is within 120 nm in 
the NE semicircle and 75 nm in the SW semicircle. Scattered to 
numerous moderate convection is noted elsewhere within about 180 
nm in the E semicircle and 90 nm in the W 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. Genevieve is a category 3 hurricane on the Saffir-
Simpson Hurricane Wind Scale. Steady weakening is expected during
the next few days, but Genevieve is forecast to remain a 
hurricane through Thu night. Swells generated by Genevieve are 
affecting portions of the Baja California Peninsula and will 
reach Southern California today. 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. A depiction of rip current risk for 
the United States can be found at:

...TROPICAL WAVES...

A tropical wave is along 88.5W, extending southward from the far
NW Caribbean Sea southward along the coast of Belize to across
portions of western Honduras and eastern El Salvador and into 
the eastern Pacific to around 03N. This wave is moving W at 
around 15 kt. Any nearby convection is described below with the 
ITCZ/monsoon trough.

A tropical wave is along 107W, from 03N to 18N, moving very
slowly W at around 5 kt. Any nearby convection is described 
below with the ITCZ/monsoon trough. 

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

The monsoon trough extends from 1008 mb low pressure over
northern Colombia at 09.5N75W to 08.5N84W to 05N92W to 13N115W.
The ITCZ extends from 11N123W to beyond 07N140W. Scattered
moderate isolated strong convection is noted from 02.5N to 07N 
between 77W and 81W, from 02.5N to 08N between 91W and 112W, from
from 08N to 18.5N between 99W and 104W, from 12N to 25N between 
105W and 109W, from 09N to 14N between 114W and 124W, and within 
120 nm to 240 nm either side of the ITCZ between 124W and 140W.

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

Please refer to the Special Features section for information on
Hurricane Genevieve with tropical storm force or greater winds 
just beyond the Baja California Sur offshore waters. Please 
refer to the Tropical Waves and Monsoon Trough/ITCZ sections 
above for information about additional convection in the region.

Away from the impacts of Genevieve, moderate to locally fresh NW
winds associated with high pressure building in from the 
northwest are impacting waters N and W of Guadalupe Island. This
same high is leading to moderate to locally fresh winds
just offshore Cabo San Lucas and in portions of the far southern
Gulf of California. Elsewhere, moderate or weaker winds prevail.
Seas are slight in the Gulf of California and moderate in the 
remaining offshore waters, except rough to very rough west of
110W and offshore Baja California due to Genevieve.

For the forecast, Hurricane Genevieve will move to 19.2N 120.7W
this evening, 19.9N 123.1W Thu morning, 20.6N 125.5W Thu 
evening, weaken to a tropical storm near 21.4N 128.0W Fri 
morning, 22.1N 130.7W Fri evening, and 23.0N 133.5W Sat morning. 
Genevieve will become post-tropical as it moves to 24.7N 139.1W
early Sun. Associated seas of rough or greater will finally 
subside across the offshore waters of Baja California through the
day Thu. Elsewhere, fresh to locally strong northerly winds are 
likely in the Gulf of Tehunatepec Thu and Fri nights. Otherwise, 
areas of fresh mainly westerly gap winds are expected through 
tonight nearshore Baja California as high pressure builds 
southward to the west of the Baja California Peninsula. Looking 
ahead, rough northerly seas may 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 Monsoon Trough/ITCZ and Tropical Wave
sections above for information about convection in the region. 

High pressure northeast of the area is forcing fresh to locally
strong easterly gap winds and seas of 5 to 7 ft across the Gulf 
of Papagayo region, with moderate 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 the weekend, with occasionally
rough seas. Pulsing moderate to locally fresh N winds are 
expected in the Gulf of Panama tonight. 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
Major 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 around the 
periphery of the ridge including from 20N to 30N and west of 
120W, and from 10N to 20N and west of 130W. Moderate to locally 
fresh SE winds are found south of 06N and west of 110W. Moderate
or weaker winds are elsewhere. Moderate seas dominate the waters
away from Genevieve.

For the forecast, Hurricane Genevieve will move to 19.2N 120.7W 
this evening, 19.9N 123.1W Thu morning, 20.6N 125.5W Thu evening,
weaken to a tropical storm near 21.4N 128.0W Fri morning, 22.1N 
130.7W Fri evening, and 23.0N 133.5W Sat morning. Genevieve will 
become post-tropical as it moves to 24.7N 139.1W early Sun. Away
from Genevieve, little change in marine conditions is forecast 
across the remainder of the waters into next weekend. Looking 
ahead, 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 this weekend into early next week.
