...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... 

A surface trough extends from near the Panama-Colombia border
across 08N105W to 07N123W. An ITCZ continues from 07N123W to 
08N138W. Scattered moderate to isolated strong convection is 
present from 04N to 08N between 80W and 87W. Scattered moderate 
convection exist from 04N to 11N between 89W and 116W, and from
07N to 11N between 127W and 130W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A 1028 mb high centered northwest of the area at 33N135W is
sustaining moderate to fresh NW to N winds across the waters 
west and southwest of the Baja California peninsula. Seas of 6 to
8 ft in northwest swell are over these waters. Gentle to 
moderate NW to N winds and seas of 2 to 4 ft are evident in the 
central and southern Gulf of California. Gentle SW to W winds 
with 1 to 2 ft seas are found over the northern part of the Gulf.
Gentle to moderate SW to NW winds along with 4 to 6 ft seas are 
over the southern Mexican offshore waters, except for light and 
variable winds in the Gulf of Tehuantepec.

For the forecast, NW to N winds will remain moderate to fresh 
just off the coast of Baja California peninsula tonight and Sat 
evening, then become gentle to moderate by Sun. Pulses of fresh 
to strong SW to W winds are expected at northern Gulf of 
California and near Cabo San Lucas Sun night and Tue night. Long-
period moderate northwest swell will subside to light west of 
Baja California peninsula tonight. This swell should rise back to
moderate west of Baja California Norte Sun night, and west of 
Baja California Sur Wed night.

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

Fresh easterly winds along with seas of 5 to 6 ft are offshore 
from the Papagayo region and southern Nicaragua. Gentle to 
moderate with locally fresh S to SW and seas at 5 to 7 ft are 
between the west of coast of Colombia and Galapagos Islands. 
Light to gentle winds and seas of 4 to 6 ft in S to SW swell 
continue across the remainder of the offshore waters.

For the forecast, fresh northeast to east winds from offshore 
the Papagayo region to the southern Nicaragua will become gentle 
to moderate east to southeast winds late on Sat afternoon. Long- 
period moderate south to southwest swell across the much of the 
region will subside to light by Mon evening, before gradually 
build again after midweek.

REMAINDER OF THE AREA

A tight pressure gradient between a 1028 mb high pressure 
located northwest of the area near 33N135W and lower pressure in
the vicinity of the ITCZ is maintaining moderate to fresh 
NE to E trades from north of the ITCZ to 26N and west of about 
125W. Long-period primarily NE swell over this area is 
maintaining seas of 6 to 8 ft. Gentle to moderate E to SE winds 
along with seas of 5 to 7 ft in moderate long-period S to 
SW swell are noted elsewhere, except in mixed swell west of 
115W.

For the forecast, the aforementioned NW swell will begin to 
decay on Sun and through early next week, allowing for the 6 to 8
ft seas to diminish in coverage. Elsewhere, little change is 
expected through the middle of next week.
