from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,

Based on 0600 UTC surface analysis and satellite imagery through

...SPECIAL FEATURES...

Tropical Storm Genevieve is centered near 21.7N 127.2W at
31/0900 UTC, moving west-northwest at 12 kt. Estimated minimum
central pressure is 993 mb. Maximum sustained wind speed is 55
kt with gusts to 65 kt. Peak seas are near 27 ft or 8.0 m.
Deep convection has rapidly diminished, with scattered moderate
convection within 120 nm SW semicircle of the system. Genevieve
is expected to maintain a steady weakening trend while continuing
on a west- northwest track through the weekend. The system is
forecast to become post- tropical late this weekend.

Swells generated by Genevieve are affecting portions of the
Baja California Peninsula and Southern California. These swells will
persist for the next day or so, and are likely to cause life-
threatening surf and rip current conditions. Please consult
products from your local weather office.

extends from 07N90W to 05N96W to 07.5N110W. A segment of the
central Pacific monsoon trough extends from southwest of
Genevieve near 14N131W to 10N140W. Scattered moderate and

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

Moderate to fresh N gap winds are 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, fresh to locally strong gap in the Gulf of
Tehuantepec will diminish today. Moderate to locally fresh NW
winds are expected to pulse tonight nearshore Baja California.
Fresh SE to S winds may pulse nightly in the northern Gulf of
California, possibly reaching strong speeds Sat night. NW swell
may lead to rough seas offshore Baja California Norte Sun night
and Mon.

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

Fresh to strong northeasterly gap winds and seas of 6 to 8 ft
are over and downstream the Gulf of Papagayo region. Moderate to
locally fresh gap wind are in the Gulf of Panama. Gentle to
moderate winds are noted between the Galapagos Islands and
Ecuador. 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. Moderate to fresh winds will then pulse thereafter.
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
Tropical Storm Genevieve.

For waters not being impacted by Genevieve, high pressure is
centered just northwest of the area. The pressure gradient
between the area of high pressure and Genevieve is supporting
moderate to fresh NE winds to the northwest of Genevieve. Seas
in this region are in the 7 to 9 ft range. Gentle to moderate
winds, and moderate seas, prevail over the remainder of the
discussion waters.

For the forecast, Tropical Storm Genevieve will move to 22.2N
129.1W this afternoon, 23.1N 132.1W Sat morning, 23.9N 134.9W Sat
afternoon, 24.7N 137.9W Sun morning, 25.5N 140.4W Sun afternoon,
and weaken to a remnant low near 26.6N 142.7W Mon morning. Away
from Genevieve, little change in marine conditions is forecast
through the weekend. 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. New large southerly swell may build south
of the Equator and west of 100W beginning Tue night.
