The axis of a tropical wave is near 103W north of 05N, moving 
westward at around 15 kt. Numerous moderate to isolated strong 
convection is evident from 13N to 18N between 95W and 105W.

The axis of a tropical wave is near 114W north of 05N, moving 
westward 5 to 10 kt. Scattered moderate convection is evident 
from 12N to 14N between 111W and 113W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A recent scatterometer satellite pass confirmed fresh to strong
winds over the Gulf of Tehuantepec, although these winds have
likely diminished this afternoon. Moderate winds are elsewhere 
south of southern Mexico. Gentle to moderate winds are west of 
Baja California Norte, except for fresh NW winds funneling off 
Punta Eugenia. Light to gentle winds are elsewhere across the 
discussion waters. Seas are in the 4-6 ft range over the open 
waters off Mexico, and 1-3 ft in the Gulf of California.

For the forecast, fresh to strong winds in the Gulf of 
Tehuantepec will pulse overnight. Winds are forecast to 
strengthen in the northern Gulf of California Thu through Fri 
night as pressure lowers over the southern Colorado River valley.
Moderate to fresh winds will be offshore Baja California Norte 
through Thu night, locally strong tonight just S of Punta Baja. 
Mainly gentle to moderate winds will prevail elsewhere. Moderate 
seas will prevail across the open waters over the next several 
days. 

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

Moderate to fresh winds are over and downstream of the Gulf of 
Papagayo. Light to gentle winds are elsewhere N of 04N. S of 
04N, gentle to moderate winds prevail. Seas are in the 4-6 ft 
range, reaching 7 ft between Ecuador and the Galapagos Islands. 

For the forecast, moderate to fresh winds will pulse across the 
Gulf of Papagayo through late Fri. Gentle to moderate winds will 
prevail between Ecuador and the Galapagos Islands. Elsewhere, 
light to gentle winds will prevail. Moderate seas in S to SW 
swell will prevail over the regional waters during the period, 
except building to rough S of the Galapagos Islands by the end of
the week. Looking ahead, fresh to strong gap winds may return to
the Gulf of Papagayo early next week. 

...REMAINDER OF THE AREA...

High pressure prevails over the waters north of 20N. Gentle to 
moderate winds prevail across the discussion waters. Southerly
swell of 7 to 8 ft is evident south of 05N and west of 110W.
Elsewhere seas are mainly 4 to 6 ft across the open waters, 
except to 7 ft south of 15N and west of 135W.

For the forecast, cross equatorial, rough southerly swell will 
continue to move into and cover the waters S of 06N and W of 
100W through the end of the week, with a reinforcing set this 
weekend. Seas may build to near 8 ft in fresh N swell along 30N 
between 120W and 130W at the end of the week into the weekend. 
Winds will freshen S of the ITCZ today, persisting into the 
weekend.
