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.

...SPECIAL FEATURES... 

Gulf of Tehuantepec Gale Warning: A cold front moving off the 
Texas coast this morning will push into the SW Gulf tonight. 
Strong winds behind the front will funnel across the Isthmus of 
Tehuantepec, with winds expected increase to gale force over the 
Gulf of Tehuantepec late Thu night. Gales are likely to persist 
through Sun night with strongest pulses during the overnight and 
early morning hours in conjunction with nocturnal drainage flow. 
Refer to the latest High Seas Forecast FZPN03 KNHC/HSFEP2 issued 
by the National Hurricane Center, and the website

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

A surface trough extends from 03N78W to 03N86W. the ITCZ 
continues from 03N86W to 06N99W to 04N106W to 07N114W to 06N128W 
to 08N140W. Scattered moderate convection is noted from 04N to 
07N between 95W and 100W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Deep layer moisture is streaming NE, east of a mid to upper-
level trough along 110W. The moisture south of the southern tip 
of Baja California into north-central Mexico could bring a few 
showers into the region.

NW winds west of Baja California will continue to diminish today 
as high pressure builds eastward. NW swell will continue in the 
waters off Baja California through mid-week. A relatively light 
wind regime prevails farther south off central and southern 
Mexico, and altimeter passes from that area show seas of 4-6 ft. 

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

Strong to near gale force winds will prevail over the Papagayo 
region through Sun night. A large area of fresh to strong NE to 
E winds is forecast to extend downwind of the source region to 
near 93W or 94W by Sat. Swell generated by the Tehuantepec and 
Papagayo gap wind events are expected to impact the offshore 
waters off Guatemala and El Salvador. 

Fresh N winds pulsing over and downwind of the Gulf of Panama 
during the overnight and early morning hours will become strong 
Sat night.

REMAINDER OF THE AREA...

Low pressure near the Hawaiian Islands has begun to weaken, and 
the gradient between the low and high pressure over the eastern 
N Pacific will relax. This will allow winds to decrease N of the 
ITCZ over the trade wind belt W of 120W during the next few days.
