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 1800 UTC surface analysis and satellite imagery through
2040 UTC.

...SPECIAL FEATURES...

Tropical Depression One-E is centered near 14.5N 116.9W at
25/2100 UTC moving NW at 6 kt. Estimated minimum central
pressure is 1006 mb. Maximum sustained wind speed is 30 kt with
gusts to 40 kt. Scattered moderate isolated strong convection is
noted within 150 nm S and 70 nm N semicircles. The depression is
forecast to continue on a NW track the next day or so with winds
to 30 kt. On Sunday, an increase in vertical wind shear and 
lower SST's is expected to lead to the weakening of the 
depression. See latest NHC forecast/advisory under AWIPS/WMO 
headers MIATCMEP1/WTPZ21 KNHC for more details.

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

A surface trough extends from 09N78W to 06N88W to 10N107W. The 
ITCZ extends from 07N120W to beyond 05N140W. Scattered moderate 
isolated strong convection is noted from 02N to 10N E of 111W. 
Scattered moderate convection was noted within 60 NM N of the 
ITCZ W of 122W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Light to gentle winds prevail over the forecast waters. Seas are
6-7 ft west of Baja California Norte and 4-6 ft elsewhere, 
except 2 ft or less over the Gulf of California. 

Weak surface troughing will prevail over the Baja California 
region through Mon. High pressure will start to build into the 
region from the west by the middle of next week. A pulse of 
fresh to strong northerly winds are likely in the Gulf of 
Tehuantepec Sun night into Monday morning. Fairly tranquil marine
conditions will prevail elsewhere through the middle of next 
week.

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

A weak pressure pattern is resulting in mostly light to gentle 
winds across the forecast waters. Seas are mainly 3 to 5 ft in a
mix of long period southerly and NW swell.

Fairly tranquil marine conditions are expected across most of 
the forecast area through Thu, except for the Papagayo region, 
where fresh to occasionally strong gap winds are possible.

REMAINDER OF THE AREA...

Please see special features above for more on TD One-E.

High pressure prevails north of the area. Outside of TD One-E, 
gentle to moderate winds prevail across the discussion area. 
Seas are in the 5-8 ft range.

Gentle to moderate winds will prevail over this area through the
beginning of next week. High pressure will start to build the 
beginning of next week which will help to freshen trade winds by 
mid-week. Long-period NW swell is expected to maintain combined 
seas of 6 to 8 ft west of 120W this weekend. S swell will support 
seas to 7-8 ft in the equatorial waters west of 100W through 
early Sun.
