Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Sun Feb 7 2021

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
2100 UTC.

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

A surface trough extends from 07N78W to 05N80W to 04N94W. The 
ITCZ continues from 04N94W to 05N110W to 04N130W to 05N140W. 
Scattered moderate convection is from 02N to 05N E of 79W to the
coast of Colombia. Similar convection is near 02N83W, and within
60 nm N of the ITCZ between 131W and 136W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge dominates the offshore forecast waters of Baja California
producing gentle to moderate northerly winds and seas generally 
in the 4-6 ft range. These marine conditions will persist over 
the next several days. Fresh to strong gap winds are expected in 
the Gulf of Tehuantepec tonight into early Mon morning as high 
pressure builds across the western Gulf of Mexico in the wake of 
a cold front. Seas will remain below 8 ft. Elsewhere, gentle to 
moderate winds are expected through late in the week.

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

A weak pressure pattern prevails across the Pacific region south
of Central America. Light to gentle winds and seas of 3-5 ft
are noted in this area. Strong trade winds across the central and
SW Caribbean will support fresh to strong offshore winds across 
the Gulf of Papagayo tonight through early Tue, and then again
Tue night and Wed. Fresh north winds through the Gulf of Panama 
will begin tonight and continue through early on Wed. Light to 
gentle winds are expected elsewhere during the period. 

REMAINDER OF THE AREA...

High pressure well to the north of the forecast area extends a 
ridge southeastward deep into the tropics south of 20N and west 
of 110W. Moderate to locally fresh trades are noted N of the ITCZ
to about 15N and W of 125W based on latest scatterometer data. 
Wave heights within this area of winds are in the 8-10 ft range 
in NW swell. These wave heights will slowly subside over the next
couple of days. Otherwise, rather benign marine conditions are 
expected to continue across the rest of the discussion area 
through the forecast period. By Wed morning, expected increasing
winds and building seas near 30N140W ahead of a cold front 
approaching the far NW corner of the forecast region. The front
will reach from 30N137W to 27N140W by Wed night, and from 30N135W
to 26N140W on Thu.
