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

A surface trough extends from Panama near 09N80W to 09N97W to 
09N112W. The ITCZ extends from 09N112W to 08N128W to beyond 
06N140W. Scattered moderate convection is from 05N to 12N and W 
of 102W and from 02N to 06N E of 80W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A weakening cold front is beginning to approach from the NW.
Ahead of the front, mainly gentle winds prevail across the
Mexican offshore waters. Seas are 4 to 6 ft, except 6 to 8 ft
offshore Baja California Norte and 1 to 3 ft in the Gulf of
California. Patches of haze are possible offshore S Mexico due 
to nearby persistent agricultural fires. 

For the forecast, gale-force northerly winds are expected across the 
Gulf of Tehuantepec late tonight through Wed morning. Fresh to 
strong northerly winds will continue through Thu afternoon in this 
region. Meanwhile, gentle to moderate northerly winds will prevail 
across the Baja California offshores through Thu, increasing to 
fresh by Thu night. The long- period NW swell will prevail NW of 
Punta Eugenia through the end of the week.

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

Light to gentle mainly N winds prevail N of the surface trough,
with gentle to moderate S winds to the S. Seas of 4-6 ft are 
noted across the Central American offshores as well as the South
American offshores. These seas are within a moderate S to SW 
swell. Patches of haze are possible offshore of Guatemala and El 
Salvador due to nearby persistent agricultural fires. 

For the forecast, long-period moderate S to SW swell will 
persist across the region through the week. Fresh easterly winds 
will begin near the Papagayo region and offshore Nicaragua on Wed
afternoon, and increase to fresh to strong Wed night into early 
Thu morning. Fresh winds will continue in that area on Thu and 
Fri.

REMAINDER OF THE AREA

Moderate to fresh trades prevail N of the ITCZ and W of 125W.  
Long- period NW to N swell throughout this area is producing seas
of 8-10 ft. Gentle to moderate winds along with seas of 5-7 ft 
seas due to long-period S to SW swell are noted elsewhere.

For the forecast, the long-period NW to N swell will gradually 
decay through tonight, which will allow for seas to subside 
through Thu. The southerly swell should sustain 5-7 ft seas 
across the remainder of the basin through the forecast period.
