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/MONSOON TROUGH...

A surface trough extends from 08N85W to 01N99W. The ITCZ extends 
from 01N99W to 03N135W. A surface trough is from 09N131W to 
02N138W. No significant convection is noted in connection with 
the ITCZ.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A large plume of mid-level moisture moving NE is producing 
widespread showers and a few embedded thunderstorms across Baja 
California and NW Mexico. A surface trough over Baja California 
Norte will continue to weaken today, then dissipate by tonight. 
Southerly winds will increase today over the northern Gulf of 
California ahead of a frontal trough that will move across the 
region tonight and Fri. A period of fresh to occasionally strong 
NW winds are expected this morning between the southern Gulf of 
California and Cabo Corrientes. Tranquil conditions are expected 
elsewhere through Sun night. 

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

Fresh NE to E winds will continue across the Gulf of Papagayo 
region through Sat, pulsing to locally strong at night. Seas in 
this area will gradually subside tonight through Fri night. No 
large swell is anticipated during the next several days.

REMAINDER OF THE AREA...

A 1015 mb surface low is centered near 30N122W, with a frontal 
trough extending southward to 20N129W. Fresh northerly winds 
associated with the front will diminish today. The low will 
drift E to SE over the next couple of days and weaken.

Gentle to moderate trade winds will prevail across most of the 
Eastern Pacific into the weekend, with seas generally 5-7 ft W 
of 115W. A large area of 8 ft seas from 06N to 11N between 94W 
and 102W originating from gap winds in Tehuantepec and Papagayo 
will diminish below 8 ft later today.
