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

A trough extends from 08N79W to 05N90W to 04N100W. The ITCZ

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A 1021 mb high is centered W of Baja California near 27N119W. A 
cold front is advancing eastward from 30N127W. Light to gentle 
winds are in the vicinity of the high over the waters west of 
Baja California Norte as well as to the west of the northern part
of Baja California Sur. Wave heights with these winds are in the
range of about 4-5 ft. Slightly stronger northerly winds, in the
gentle to moderate range, are over the rest of the offshore 
waters to west of Baja California Sur, with slighter higher wave 
heights in the range of 5-7 ft. These conditions are forecast to 
continue through the weekend. A 1010 mb low is to the north of 
the area near 33N131W will move ENE to southern California Mon.

The tightening pressure gradient associated with the approaching
cold front will produce fresh breeze winds along the w coast of
Baja California Mon with wave heights of 5-6 ft. Similar winds 
are expected along and to within about 60 nm of the Mexican coast
during the night time and early morning hours from Manzanillo to
Cabo Corrientes through Sun afternoon.
 
Looking ahead, the cold front will weaken as it moves across the
waters west of the northern part of Baja California Norte Sat
evening. Another cold front will reach 30N128W Sat evening.

A developing trough over the Bay of Campeche this weekend will 
lead to a narrow plume of fresh to strong north winds across the
Gulf of Tehuantepec beginning Sat evening through Sun evening 
before winds diminish to moderate to fresh speeds. These winds 
are expected to peak at a range of 20-30 kt early Sun morning 
over most of the Tehuantepec area, with 8-9 ft wave heights.

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

Strong high pressure over the northern Caribbean will maintain
the pattern of fresh to strong northeast to east winds pulsing at 
night and into the morning hours over the Gulf of Papagayo 
region and at fresh speeds during the rest of the mornings and 
during the afternoons through early next week. Wave heights are 
forecast to peak to 8 or 9 ft with these winds at night. 

Expect gentle to moderate winds to remain elsewhere across the 
offshore waters through early next week.
