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

A surface trough extends from Panama near 08N82W to 10N103W to 
08N131W. The ITCZ extends from 08N131W to beyond 08N140W. 
Scattered moderate convection is noted from 05N to 13N between 
88W and 135W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Moderate NW winds are occurring NW of Punta Eugenia, along with 
seas of 8 to 9 ft. Gentle to moderate N winds prevail elsewhere 
W of Baja California, with seas of 5 to 7 ft in NW swell. Fresh
to strong winds are noted in the northern Gulf of California with
gentle winds occurring across the rest of the Gulf. Seas are up
to 4 ft in the northern Gulf with 2 to 3 ft elsewhere. Strong
winds continue across the Gulf of Tehuantepec with seas 8 to 10
ft. Elsewhere across the southern Mexican offshores, light to 
gentle winds prevail with seas 4 to 6 ft.

For the forecast, fresh to strong northerly winds continue 
through Thu afternoon in the Gulf of Tehuantepec. The strong
winds across the Gulf of California will diminish later tonight,
with moderate to locally fresh winds continuing through Fri
morning. Moderate northerly winds will prevail across the Baja 
California offshores through Thu, increasing to fresh to locally
strong by Thu night. The long- period NW swell will persist NW 
of Punta Eugenia through early next week. 

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

Light to gentle mainly NE winds prevail N of the surface trough,
with gentle to locally moderate S winds to the S of the trough. 
Fresh to strong winds are prevailing near the Papagayo region 
and offshore Nicaragua. Seas of 4 to 6 ft in S to SW swell are 
prevail across the waters, with the exception of 5 to 7 ft seas 
in mixed swell in the Papagayo region and near the Galapagos
Islands. Scattered moderate to isolated strong convection is
noted off the El Salvador coast, with scattered moderate 
convection continuing offshore Costa Rica and Panama. 

For the forecast, long-period moderate S to SW swell will persist
across the region through the week. The strong easterly winds 
will diminish across the Papagayo region and offshore Nicaragua 
by Thu morning. Expect pulsing moderate to fresh winds across
this region through Fri.

REMAINDER OF THE AREA

Moderate to fresh trades prevail N of the ITCZ and W of 115W. 
Long- period NW to N swell throughout this area is producing seas
of 8 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 continue
decaying today, which will allow for seas to subside through 
Thu. The southerly swell should sustain 5 to 7 ft seas across 
the remainder of the basin through the week. Seas in the far 
western forecast area, N of 09N and W of 125W, could see 
northerly swell with seas 8 to 10 ft return by the weekend.
