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
0800 UTC.
...SPECIAL FEATURES...
Hurricane Genevieve is centered near 18.4N 118.4W at 29/0900
UTC, moving west-northwest at 8 kt. Estimated minimum central
pressure is 956 mb. Maximum sustained wind speed is 105 kt with
gusts to 130 kt. Peak seas are near 35 ft, or 11 m. Numerous
moderate convection is within 120 nm of the center, with numerous
moderate convection also extending from 12N to 16N between 112W
and 116W. Genevieve is moving toward the west- northwest, and
this general motion with a slight increase in forward speed is
expected during the next few days. Genevieve is now a category 3
hurricane on the Saffir- Simpson Hurricane Wind Scale. Some
fluctuations in intensity are possible over the next day or so,
and a weakening trend should begin thereafter. Swells generated
by Genevieve are affecting portions of the Baja California
Peninsula and will reach Southern California later today. These
swells are likely to persist for a few more days, and could cause
life- threatening surf and rip current conditions. Please
consult products from your local weather office.

Hurricane Center at website -

...TROPICAL WAVES...
A tropical wave is along 87W, extending southward from the Gulf
of Honduras, across Honduras and Nicaragua, and into the far
eastern Pacific to around 06N. This wave is moving W at around
10 kt. Scattered moderate convection has developed just offshore
El Salvador in association with this wave.
A tropical wave is along 107W, from 05N to 16N, moving W at
around 5 kt. Scattered moderate to isolated strong convection is
noted from 06N to 16N between 106W and 109W.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough extends from 10N81W to 06N93W to 09N107W. The
ITCZ has become defined from 10N130W to 08N140W. Numerous
moderate to isolated strong convection is noted from 01N to 17N
between 91W and 103W.
...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
now just beyond the 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.
For the forecast, Hurricane Genevieve is near 18.4N 118.4W at 2
AM PDT, and is moving west-northwest at 8 kt. Maximum sustained
winds are 105 kt with gusts to 130 kt, and the minimum central
pressure is 956 mb. Genevieve will move to 18.8N 119.8W this
afternoon, 19.5N 122.0W Thu morning, 20.2N 124.4W Thu afternoon,
and 21.0N 127.0W Fri morning. Genevieve will weaken to a tropical
storm near 21.8N 129.5W Fri afternoon, then be near 22.5N 132.3W
Sat morning. Genevieve will become post-tropical as it moves to
well west of Baja California Sur early Sun. Associated seas of
rough or greater will finally subside across the offshore waters
of Baja California 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.
...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 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 tonight 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, 1025 mb
high pressure centered near 33N140W dominates. 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 07N and west of 115W as well as
S of the Equator and W of 105W. Moderate or weaker winds are
elsewhere. Moderate seas dominate the waters away from Genevieve.
For the forecast, Hurricane Genevieve will move to 18.8N 119.8W
this afternoon, 19.5N 122.0W Thu morning, 20.2N 124.4W Thu
afternoon, and 21.0N 127.0W Fri morning. Genevieve will weaken to
a tropical storm near 21.8N 129.5W Fri afternoon, then be near
22.5N 132.3W Sat morning. 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.
