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 0000 UTC surface analysis and satellite imagery through
0320 UTC.
Updated Forecast paragraph in the Offshore Waters section for
Central America, Colombia and near Ecuador
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A trough extends from 07N77W to a 1009 mb low near 06N78W
then extends southwestward to 02S104W. The ITCZ extends from
01S116W to 01S140W. Scattered moderate convection is depicted
from 07N to 05S between 82W and 96W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A broad surface ridge extends southeastward from a 1019 mb high
near 26N130W to the southeast of Revillagigedo Islands. This
ridge dominates the offshore waters of Baja California and
central Mexico, supporting gentle to moderate NW to N winds and 6
to 7 ft seas in moderate NW swell. Fresh to strong northerly gap
winds with seas around 6 ft are present over the Gulf of
Tehuantepec. Otherwise, light to gentle winds and seas of 4 to 6
ft in mixed moderate swells prevail for the rest of the southern
Mexico offshore waters. In the Gulf of California, light variable
winds and 1 to 3 ft seas prevail.
For the forecast, the aforementioned high pressure will sustain
gentle to moderate NW to N winds west of Baja California until
Wed. Moderate to fresh gap winds at the Gulf of Tehuantepec will
become strong to near-gale force tonight before subsiding on Wed
night. Residual NW swell is going to maintain moderate seas off
Baja California and near the Revillagigedo Islands through Fri.
Looking ahead, a new high pressure will build in the wake of a
cold front causing winds to increase to moderate to fresh speeds
with locally strong winds Thu and through the weekend west of
Baja California. Additionally, a new set of large NW swell
related to the aforementioned cold front is expected to cause
very rough seas in the same area by Fri night.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Moderate to fresh trade winds across the southwestern Caribbean
are sustaining fresh to strong NE to E winds along with 5 to 6
ft seas over the Papagayo region, and the far southwestern
offshore waters of Guatemala/El Salvador. Moderate to locally
fresh northerly winds and seas of 3 to 5 ft are noted in the
Gulf of Panama. Otherwise, mostly gentle NW to NE winds and seas
at 3 to 5 ft dominate offshores of Central America and Colombia.
Near the Galapagos Island and Ecuador, mainly gentle west winds
and 5 to 6 ft seas prevail.
For the forecast, moderate to fresh trades across the
southwestern Caribbean Sea will continue to support fresh to
strong NE to E winds at the Papagayo region through Fri,
especially during the nighttime hours. These winds will also
cause rough seas across the Papagayo regional offshore waters,
and over the far southwestern offshore waters of El Salvador. In
the Gulf of Panama, gentle to moderate with locally fresh
northerly winds will persist through Fri. In the long term,
trades at the southwestern Caribbean should subside on Sat which
will allow winds at the Papagayo region to decrease.
...REMAINDER OF THE AREA....
A cold front is approaching 30N139W from the west. Ahead of this
front, moderate to fresh SW winds prevail along with seas 8 to 10
ft. Otherwise, a broad surface ridge extends southeastward from
a 1019 mb high near 26N130W to the southeast of Revillagigedo
Islands. North of 20N and west of 120W, this feature is
supporting gentle to moderate variable winds. Seas in the region
are from 6 to 8 ft in moderate NW swell. From 20N southward to
near the ITCZ, moderate to locally fresh NE to E winds with 6 to
8 ft seas are seen west of 110W. Gentle to moderate NW to NE
winds with seas of 4 to 6 ft in mixed moderate swells are present
elsewhere.
For the forecast, the high pressure will gradually weaken while
the aforementioned cold front continues to move through the East
Pacific toward Baja California tonight through Fri. Large NW
swell associated with this front will cause seas north of 16N to
build and become very rough over the next several days. This
front will reach from 30N135W to 26N140W by Wed morning, and from
30N131W to 25N140W by Wed night. As this front gradually weakens
this weekend, decaying NW swell should allow seas to slowly
subside.
