based on satellite imagery, weather observations, radar, and
meteorological analysis.

Based on 1200 UTC surface analysis and satellite imagery through
1500 UTC.

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

A surface trough extends from 09N83W to 07N89W to 04N93W. The 
ITCZ continues from 04N93W to 05N111W to 03N125W to 04N140W.
Scattered moderate isolated strong convection was noted from 02N
to 07N E of 87W. Scattered moderate convection was noted from 02N
to 07N between 117W and 130W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge extends west of the Baja California peninsula. The
pressure gradient between the ridge and a trough over the Gulf of
California is supporting fresh to strong winds west of Baja
California Norte and moderate to fresh winds off Baja California
Sur. Moderate to locally fresh winds are funneling into the Gulf
of Tehuantepec. Light to gentle winds prevail elsewhere. Seas are
in the 5-8 ft range off the coast of Baja California, and 4-5 ft
over the remainder of the open waters off Mexico. Seas are in the
1-3 ft range over the Gulf of California. 

Moderate to fresh northerly winds will continue over the Gulf of
Tehuantepec through early in the afternoon. Moderate to fresh SW
to W winds are forecast over the Oaxaca adjacent waters Fri and 
Sat. Fresh to locally strong NW winds will prevail over the Baja 
California Norte offshore waters through Sat. NW swell will move 
into the waters off Baja California Norte Sat, with seas building
to 10-11 ft by Sat night.  

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

Fresh to strong winds, and seas of 5-7 ft prevail over the Gulf 
of Papagayo. Moderate to fresh winds, and seas of 5-6 ft, 
prevail over the Gulf of Panama. Light to gentle winds, and seas
of 4-5 ft, prevail elsewhere.

Fresh to strong NE to E winds in the Gulf of Papagayo region 
will diminish to moderate to fresh today and below moderate 
speeds on Wed. Moderate to fresh N to NE winds in and downstream 
of the Gulf of Panama will continue through early this evening 
before diminishing. Light to gentle winds will prevail across the
remainder of the region through the forecast period.

REMAINDER OF THE AREA...

A ridge of high pressure prevails over the northern waters east 
of 130W. A dissipating stationary front extends from 30N130W to 
21N140W. A weak pressure gradient prevails across the forecast 
waters, with gentle to moderate winds prevailing north of the 
ITCZ to near 20N and west of 120W. Gentle to moderate winds are 
also noted N of 20N between 115W and 125W. Light to gentle winds 
prevail elsewhere. Seas are in the 7-8 ft range over the waters N
of 20N and west of 130W in subsiding NW swell. Seas of 5-7 ft 
prevail elsewhere. 

A weak pressure gradient will continue over the area through the
end of the week with little change in winds expected. High
pressure will start to build over the northern waters later this
week, strengthening tradewinds north of the ITCZ to near 15N and
west of 130W Fri into Sat. The NW swell will subside below 8 ft 
today. Northerly swell will enter to northern forecast waters 
E of 125W Fri. Seas over this area will build to near 11 ft by 
Sat night.
