Gulf of Tehuantepec Gale Warning: Strong high pressure ridging
building behind a frontal boundary in the Gulf of Mexico will
continue to support a gap wind event with gale force winds to 40
kt in the Tehuantepec region. These conditions will continue
through Sun night, allowing for seas to build up to 14 ft at
times. For more information on this event, see the latest East

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends off the coast of Colombia near 07N77W
to 06N100W. The ITCZ begins W of a pair of troughs near 09N121W
to 06N140W. Scattered moderate convection is noted within 100 nm
on either side of the trough and ITCZ.
OFFSHORE WATERS WITHIN 250 NM OF MEXICO
Please refer to the Special Features section above for details
on the Gale Warning for the Gulf of Tehuantepec.
Gentle to moderate N to NW winds are off the Baja peninsula and
the Gulf of California with seas to 3 ft in the gulf and 3 to 5
ft elsewhere off Baja California. Gale force winds continue in

Otherwise, light to gentle variable winds are elsewhere across
the SW Mexican offshores with seas to 5 ft.
For the forecast, gale-force winds will continue across the Gulf
of Tehuantepec through Sun night with seas building to 14 ft.
A weak cold front will move into the northern Gulf of California
and off of Baja California Norte on Sat. Fresh to strong winds
can be expected in the northern Gulf on Sat morning with seas to
4 ft. The front will stall and dissipate over Baja California
Sur and the southern Gulf of California Sun morning.
OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and
WITHIN 750 NM OF ECUADOR
Strong high pressure over the W Atlantic extending to the
northern Caribbean continue to support fresh to strong NE to E
gap winds across the Papagayo region with seas to 6 ft. Light to
gentle variable winds with seas to 6 ft are elsewhere, except for
moderate SW winds off the coast of Colombia and Ecuador.
For the forecast, fresh to strong NE to E gap winds will pulse
across the Papagayo region through the middle of next week with
seas building to 9 ft over the weekend. Winds will pulse
moderate to fresh across the Gulf of Panama tonight through
early next week. Elsewhere, winds should remain tranquil for the
next several days. Large NW to N swell from the Gulf of
Tehuantepec will impact the Guatemala and El Salvador offshore
waters Sat night through Sun night.
REMAINDER OF THE AREA
A 1008 mb low is near 24N141W. Fresh to strong winds are noted
north of the low in latest scatterometer data where seas are in
the 8 to 14 ft range. There is no convection associated with the
low in the area. This system is expected to continue moving westward
into hostile environmental conditions and development into a
subtropical or tropical cyclone is not expected.
For the forecast, high pressure building N of the low pressure
will continue to support a large area of fresh to strong E winds
tonight. As the low moves west, it will substantially weaken.
Winds and seas are expected to diminish by tomorrow morning.
