Tropical Weather Discussion for the eastern Pacific Ocean from
the Equator to 32N, east of 140W. The following information is
based on satellite imagery, weather observations, radar, and
meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through 
0845 UTC. 

...TROPICAL WAVES...

The axis of a tropical wave is near 85W, moving W at 15 kt. 
Scattered moderate isolated strong convection is from 07N to 11N 
between 82W and 88W.

The axis of a tropical wave is near 96W, moving W at 10 kt. 
Scattered moderate isolated strong convection is from 05N to 10N 
between 94W and 100W.

The axis of a tropical wave is near 105W, moving W at 10-15 kt. 
Scattered moderate isolated strong convection is from 07N to 13N 
between 104W and 111W. 

The axis of a tropical wave is near 125W, moving W at 10-15 kt. 
Scattered moderate isolated strong convection is from 05N to 11N 
between 123W and 132W.  

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

The monsoon trough extends from 09N83W to 10N100W to 12N108W to 
08N124W to 09N136W. The ITCZ begins near 09N136W and continues 
to 09N140W. Scattered moderate isolated strong convection is N 
of 03N E of 80W. For more information about convection, see the 
tropical waves section above. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 

A weak pressure pattern prevails over the forecast waters 
supporting light to gentle variable winds. Long period 
southwesterly swell continues to impact the region with seas in 
the 5-6 ft range. Long period swell will gradually subside 
through the end of the week. A surface trough along Baja 
California will deepen on Tue, resulting in moderate to fresh SE 
flow over the Gulf of California. Winds will strengthen to 
strong N of 29N on Tue night, and across the remainder gulf 
early on Wed, continuing through Wed evening. Northerly swell 
will propagate into the waters off Baja California Norte, with 
seas in the 6-8 ft range Tue and Wed before subsiding. 

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

The monsoon trough is positioned along 09N-10N across the 
Central American offshore waters. Latest scatterometer pass 
indicates moderate SW flow south of the trough, and moderate to 
fresh NE winds N of the monsoon trough. Winds will pulse to 
fresh to strong across the Gulf of Papagayo during the overnight 
hours through Fri. Long period southwest swell continues to 
impact the forecast waters, with seas in the 8-9 ft range 
prevailing over Colombia and Panama offshore waters. Seas will 
gradually subside through tonight.

REMAINDER OF THE AREA... 

The remnant low pressure of TD Four-E, is centered near 19N118W. 
An earlier scatterometer pass show moderate winds within 210 nm 
N semicircle of the low. This remnant low will dissipate today. 

High pressure is centered N of the forecast area near 32N136W.
The pressure gradient between the area of high pressure and 
lower pressure in the vicinity of the monsoon/ITCZ is supporting 
moderate to fresh tradewinds N of the monsoon/ITCZ to 20N and 
west of 123W. Seas over this area are in the 6-8 ft range.

Long period SW swell remains across much of the southern waters. 
The latest altimeter data indicates 8-9 ft seas cover much of 
the area south of 15N and east of 120W. Seas will gradually 
subside through Tue.
