Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 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
0900 UTC.

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

The monsoon trough extends from 08N78W to 07N82W to 14N105W to 
07N123W. The ITCZ continues from 07N123W to 04N140W. Scattered 
moderate convection is noted from 02N to 08N between 81W and 
90W, and from 08N to 13N between 101W and 109W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A broad ridge associated with high pressure is west of the Baja 
California peninsula. The gradient between the ridge and low 
pressures over Mexico is supporting gentle to moderate NW winds 
near the Baja California peninsula, and light to gentle winds 
elsewhere over the waters off Mexico. Seas are 5 to 6 ft in a 
mix of west and southwest swell over the open waters off Mexico.

For the forecast, moderate to fresh NW to N winds will prevail 
west of Baja California through Mon. Fresh to strong winds will 
filter through Baja California passages into the northern and 
central Gulf of California Sun night. Large NW swell will build 
west of Baja California Sun and Mon. Tranquil marine conditions 
are expected across the region Tue and Wed. 

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

Scatterometer data indicates light to gentle winds prevail across
most the region. Seas are in the 5 to 6 ft range in lingering 
southerly swell.

For the forecast, light to gentle winds will prevail across most
of the region through Sun. Southerly winds will increase south 
of the monsoon trough axis Sun night and Mon. 

REMAINDER OF THE AREA...

A broad ridge associated with high pressure centered north of the
area dominates the forecast waters. The area of high pressure is
bisected by a weak stationary front that extends from 34N135W 
through 32N140W to 30N140W. The gradient between the high and 
lower pressures near the ITCZ is supporting moderate trade winds
north of the ITCZ, and 5 to 7 ft seas. Gentle to moderate winds 
and seas in the 5-6 ft range prevail elsewhere.

High pressure will continue north of the area through the  
weekend. Large northwest swell and fresh to strong northerly
winds will spread south of 30N between 120W and 130W Sun and 
Mon. Marine conditions will improve considerably Tue and Wed.
