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...

The ITCZ extends from 06N89W to 01N106W to 05N124W to beyond 
04N140W. Scattered moderate convection is noted from 00N to 05N 
between 89W and 106W, and from 02N to 06N between 130W and 140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Moderate to fresh NW winds prevail west of Baja California Norte
while fresh to strong winds are noted west of Baja California 
Sur. Light to gentle winds are noted over the northern Gulf of 
California, with fresh to strong winds over the southern part of 
the Gulf of California. Mainly light to gentle winds are noted 
elsewhere. Seas are 6 to 7 west of Baja California Norte and 7 to
9 ft west of Baja California. Over the northern Gulf of 
California, seas are 2 ft or less ft, with seas in the 5 to 8 ft
range over the southern Gulf of California. Seas are in the 4 to
6 ft range elsewhere.

Winds in the southern half of the Gulf of California will
continue in the fresh to strong range through tonight. Strong
winds near Cabo Corrientes will gradually today. Gentle to 
moderate winds will prevail elsewhere over the offshore waters 
west of southern Mexico. A weakening cold front will cross Baja 
California Mon into Tue. In the wake of this front, strong winds 
are possible in the northern Gulf of California.

Looking ahead, gale force gap winds are forecast to develop in 
the Gulf of Tehuantepec later this week.

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

Fresh to strong NE to E winds are noted within and downstream of 
the Papagayo region. Moderate to fresh winds are in and 
downstream of the Gulf of Panama. Light to gentle winds prevail 
elsewhere. Sea heights are generally 3 to 5 ft, except 6 to 7 ft
downwind from the Gulf of Papagayo. Fresh to strong NE winds 
will continue to pulse across the Papagayo region into Tue, with 
highest winds expected during the overnight hours. Seas 
associated with these winds will be 6 to 8 ft. Fresh north winds 
in the Gulf of Panama will pulse at night into Tue. Light to 
gentle winds, with seas in the 3 to 6 ft range, will prevail 
elsewhere into mid week.

REMAINDER OF THE AREA...

High pressure of 1028 mb is centered near 30N125W. The pressure 
gradient between this area of high pressure and lower pressure in
the vicinity of the ITCZ is supporting moderate to fresh winds 
north of the ITCZ to near 20N. Seas in this area are in the 8-11
ft range. A cold front has moved into the NW waters, from 30N135W
to 27N140W. Fresh to strong northeasterly winds are noted west 
of the front with moderate to fresh southwesterly winds ahead of 
the front. The front will shift across the waters north of 25N 
through early this week before weakening. The front has ushered 
in a new set of large NW swell into the area, with seas reaching 
near 14 ft over the far NW waters this morning. This swell will 
move through the northern waters through Tue, peaking near 15 ft 
over the NW waters today.
