Tropical Weather Discussion

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 
0900 UTC.

...INTERTROPICAL CONVERGENCE ZONE... 

The ITCZ axis extends from 03N102W to 02N132W with no sizable 
areas of significant convection. 

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A cold front from SW Arizona across extreme northern part of the 
Gulf of California and northern Baja California will shift east 
across Baja California Norte and the northern Gulf of California 
today. High pressure behind the front will maintain fresh NW 
winds west of Baja California this morning. Strong high pressure 
building near 33N132W early next week will increase the coverage 
of strong northwest winds north of 25N off the coast of Baja 
California Norte early next week. Seas in the 6-8 ft range will 
prevail over this area through Monday. Northwesterly swell will 
propagate into the waters off Baja California Norte Monday, and 
peak near 12 ft early Tuesday morning. 

Gentle to moderate northerly winds and seas of 2-3 ft are 
expected across northern Gulf of California with the frontal 
passage. Winds are forecast to increase to 15-20 kt with seas 
building to 6 ft Tuesday and Wednesday as the above mentioned 
area of high pressure builds and tightens the pressure gradient 
over the area. Elsewhere, winds will generally be light to gentle
with seas in the 4-6 ft range through the middle of next week. 

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

Fresh NE winds are expected over the Gulf of Papagayo during the 
late night and early morning hours through Monday morning. Light 
to gentle winds and seas of 3-5 ft are expected elsewhere the 
next several days except in the Gulf of Panama, where winds will 
pulse to a fresh breeze at night. 

REMAINDER OF THE AREA...

A cold front extends across NE waters from 30N116W to 25N130W. 
High pressure behind the cold front extends a ridge SE to near 
the Revillagigedo Islands. On the southern periphery of the 
ridge, fresh to strong trades prevail from 07N to 19N W of 130W. 
Seas have built to 10-11 ft within the area of strongest trade 
winds based on altimeter data. This area of trades will persist 
through Monday, and the aerial extent of the fresh trades will 
increase by Monday night as high pressure located north of the 
area near 34N133W strengthens.
