Tropical Weather Discussion

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 1200 UTC surface analysis and satellite imagery through
1400 UTC.

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

A surface trough is analyzed from 06N77W to 03.4S83.5W. The ITCZ
extends from 03.4S110W to 03.4S117W. Another ITCZ extends from
03N132W to beyond 03N140W. Scattered moderate isolated strong 
convection is noted within 75 nm of the coast of Colombia and
Ecuador, and from 02N to 05.5N between 132W and 140W. 

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Strong winds and seas of 7 to 9 ft prevail over the Gulf of 
Tehuantepec. High pressure is starting to build SE toward Baja
California, causing moderate to fresh NW winds offshore Baja
California Norte. Elsewhere, a weak pressure gradient is leading
to light to gentle winds. Moderate seas prevail over the open 
waters off Mexico, with slight seas over the Gulf of California.

For the forecast, a tightening pressure gradient offshore Baja
California will increase winds to fresh to locally strong through
tonight N of Cabo San Lazaro. The pressure gradient between high
pressure over NE Mexico and the equatorial trough will support
strong gap winds in the Gulf of Tehunatepec tonight and Tue
night. High pressure will build over the waters N of Punta 
Eugenia by mid-week. This will further tighten the pressure 
gradient to support fresh to strong NW winds and building seas
off Baja California.

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

Strong gap winds are in the Papagayo region, and also in the 
Gulf of Panama, with seas in both areas at 5 to 7 ft. Elsewhere, 
winds are mainly light to gentle with slight to moderate seas. 
Scattered moderate convection has moved offshore Ecuador and 
Colombia and is impacting nearshore waters. 

For the forecast, pulsing fresh to strong winds are expected in 
the Papagayo area through through the week. Winds will increase 
to 30 kt late tonight into Tue morning with seas building to 8 
to 9 ft downwind of the Papagayo region to near 90W. Fresh N gap
winds and moderate seas will pulse in the Gulf of Panama and 
just S of the Azuero Peninsula, except fresh to strong trough Tue
night.

...REMAINDER OF THE AREA...

High pressure centered just N of the region is dominating much 
of the waters N of 10N. This is leading to mainly moderate or 
weaker NE to E winds N of the Equator along with moderate seas, 
except to fresh from 05N to 22N and W of 135W with seas to rough.
A surface trough is analyzed from 06N123W to 00N120W with
scattered moderate convection noted from 01N to 08N between 117W
and 125W.

For the forecast, little change in marine conditions is expected
into mid week. High pressure will build over the area Wed and 
Thu, tightening the pressure gradient. As this occurs, areas of 
locally strong winds and rough seas are possible N of 15N and W
of 115W for the latter half of the week.
