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
1500 UTC.
...SPECIAL FEATURES...
Gulf of Tehuantepec Gale Warning: The pressure gradient induced
by broad high pressure extending southwestward across the Gulf
of America is slowly lessening, as the high pressure continues to
drift slowly E-NE. Gale-force N to NE gap winds across the Gulf
of Tehuantepec overnight have diminished to below gale force this
morning, with strong gap winds 20 to 30 kt extending from the
coast of Tehuantepec offshore to near 13N, and are expected to
steadily diminish to less than 20 kt by late afternoon today.
Seas across this area are currently 8 to 11 ft, and will also
subside steadily throughout the day. Gale force conditions are
not expected across the area throughout the remainder of the
week.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends from 10N76W to 02N84W to 04.5N93W to
03.5N104W. The ITCZ extends from 04.5N105W to 06N137W to beyond
05.5N140W. Scattered moderate convection is noted from 02N to 05W
east of 81.5W, from 02.5N to 06.5N between 85W and 106W, and from
02.5N to 07N between 110W and 137W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Please see SPECIAL FEATURES above for more information on the
Gulf of Tehuantepec gale-force gap wind event. Fresh to strong N
to NE winds extend well offshore of Tehuantepec to near
12.5N97W, where NE swell is maintaining seas to 8 ft.
Beyond the Tehuantepec region, weak high pressure remains W of
the area, while broad low pressure persists from offshore of Baja
Norte southward across the waters well offshore waters of Baja
Sur along 120W. This weak pressure pattern is producing light to gentle
cyclonic winds across the near and offshore waters of Baja
California, with moderate NW winds along the coast near Cabo San
Lucas. Gentle to moderate southerly winds are occurring across
northern portions of the Gulf of California. Light to gentle
winds dominate the remainder of the waters between Puerto Angel
and the Revillagigedo Islands. Slight to moderate seas of 4 to 5
ft in NW swell prevail offshore Baja California and W of 105W.
For the forecast, aside from the current Gulf of Tehuantepec gap
wind event, broad low pressure is expected to persist across the
waters of Baja California through today then drift NW and
dissipate through Tue. Gentle to moderate winds will prevail
across the majority of the waters through Wed, with moderate to
fresh southerly winds developing in the northern Gulf of
California. The pressure gradient will tighten thereafter, as
high pressure gradually builds across the area from the NW late
Wed through Fri. Winds offshore of Baja California are expected
to increasing to moderate to fresh by Thu. Slight to moderate
seas will prevail through Thu, with moderate cross-equatorial S
swell moving into the Mexican waters Thu afternoon and night.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Fresh to strong NE to E winds prevail over the Papagayo region,
and extend southwestward to near 92W, where seas are 6-9 ft.
Across the Gulf of Panama, moderate to fresh N to NE winds
prevail, and extend downwind to 03.5N, where moderate seas to 6
ft in S swell prevail. Winds are light to gentle elsewhere.
Moderate seas prevail across the remaining waters.
For the forecast, fresh to strong NE to E winds will pulse across
and downwind of the Papagayo region to near 92W through early
Wed, then become moderate to fresh thereafter. In the Gulf of
Panama, fresh N to NE winds will continue to pulse through early
Tue, building seas to rough at times. Rough seas in NW swell will
continue to spread offshore Guatemala this morning due to the
recent Gulf of Tehuantepec gale event. Slight to moderate seas
will prevail otherwise through Tue night. Large SW swell will
spread to the waters from offshore Ecuador to the Galapagos
Islands Wed and build seas to 8-9 ft Thu.
...REMAINDER OF THE AREA...
Complex low pressure system remains centered NW of the local
area, and continues to weaken this morning. A weak cold front
extends across the far NW waters along 136W, with moderate S-SW
just ahead of the front, and moderate W winds behind the front.
Gentle to moderate anticyclonic winds prevail across the open
waters N of 20N, while moderate to fresh easterly winds are
noted from 05N to 16N and W of 108W. Fresh NE to E winds extend
from the Gulf of Tehuantepec gap wind event beyond 100W, into the
waters along 108W. Moderate seas in mixed swell prevail across
the remainder of the waters.
For the forecast, gentle to moderate winds will dominate the open
waters through the next several days, with weak high pressure
across much of the area and broad low pressure across Baja
California. A series of weak frontal boundaries will move into
the NW waters and weaken W of 130W throughout the week. N to NE
swell generated by a gale-force gap wind event in the Gulf of
Tehuantepec will spread SW and impact the waters roughly N of 05N
and E of 110W through this evening. Fresh to strong winds will
pulse across these waters as well extending downwind from
Tehuantepec and into the trade wind zone east of 110W. Moderate
seas will continue otherwise through the early part of the week.
Large southerly swell will move into the waters S of the Equator
mid-week and reach 10N by Thu.
