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
0430 UTC.

...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: North to northeast minimal
gale-force winds of 30 to 35 kt will begin across the Gulf of
Tehuantepec late tonight, 27/0600 UTC. Gales are forecast to 
continue through Wed afternoon, with fresh to strong winds 
prevailing across the region through Thu afternoon. Seas will 
build 8 to 10 ft late tonight through Wed night. Please read the
latest High Seas Forecast issued by the National Hurricane 
Center website: 
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. 

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

A surface trough extends from the coast of Costa Rica near 09N84W
to 09N99W to 08N115W. The ITCZ extends from 09N115W to 07N130W 
to beyond 06N140W. Scattered moderate convection is noted from 
03N to 10N and E of 100W and from 07N to 13N and W of 103W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Surface ridging continues to prevail west of the Baja 
California peninsula. The pressure gradient between the high 
pressure NW of the area and lower pressure over Mexico is 
supporting moderate NW to N winds off Baja California Norte. 
Light to gentle N winds prevail across Baja California Sur. Seas
mostly range 5 to 7 ft in long- period NW swell across the 
western offshore waters of Baja California. Seas of 8 to 9 ft 
are noted in the extreme northwest portions of the Baja 
offshores. Light to gentle winds and seas of 5 to 7 ft in mixed 
swell are noted across the S Mexico offshore waters. Gentle to 
moderate NW winds prevail across the Gulf of California. Seas are
up to 4 ft at the entrance of the Gulf of California, and 2 to 3
ft elsewhere in the Gulf. Patches of haze are possible offshore 
S Mexico due to nearby persistent agricultural fires. Thunderstorms
are also noted along the eastern coast of the Gulf of
Tehuantepec, north of 13N and E of 94W. 

For the forecast, gale- force northerly winds are expected 
across the Gulf of Tehuantepec late tonight through Wed 
afternoon. Fresh to strong northerly winds will continue through 
Thu afternoon in this region. Meanwhile, gentle to moderate 
northerly winds will prevail across the Baja California offshores
through Thu, increasing to fresh by Thu night. The long- period 
NW swell will prevail NW of Punta Eugenia through the end of the 
week.

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

Light to gentle mainly N winds prevail N of the surface trough,
with gentle to moderate S winds to the S. Seas of 4-6 ft are 
noted across the Central American offshores as well as the South
American offshores. These seas are within a moderate S to SW 
swell. Patches of haze are possible offshore of Guatemala and El 
Salvador due to nearby persistent agricultural fires. Scattered
moderate to isolated strong convection is moving off the coast of
Colombia from 02N to 07N and E of 78W. Isolated thunderstorms are
noted across the Central American coastline from Guatemala to
Panama. 

For the forecast, long-period moderate S to SW swell will persist
across the region through the week. Fresh easterly winds will 
begin near the Papagayo region and offshore Nicaragua on Wed 
afternoon, and increase to fresh to strong Wed night into early
Thu morning. Fresh winds will continue in that area on Thu and 
Fri. Patchy smoke from agricultural fires in southern Mexico and 
northern Central America may impact waters offshore Guatemala and
El Salvador at times.

REMAINDER OF THE AREA

The gradient between high pressure centered N of the area and
lower pressure along the ITCZ is supporting moderate to fresh NE
winds N of the ITCZ and W of 120W. Long- period NW to N swell 
throughout this area is producing seas of 8-10 ft. Gentle to 
moderate winds along with seas of 5-7 ft seas due to long-period 
S to SW swell are noted elsewhere.

For the forecast, the long-period NW to N swell will gradually 
decay through Tue night, which will allow for seas to subside
through Thu. The southerly swell should sustain 5-7 ft seas 
across the remainder of the basin through the forecast period.
