NWS National Hurricane Center Miami FL
2205 UTC Mon Mar 15 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...

Surface trough extends from 09N84W to 07N89W. The ITCZ extends 
from 07N89W to 02N114W to 05N140W. Scattered moderate convection
is noted from 03N to 08N between 90W and 108W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Moderate NW winds prevail west of Baja California, while gentle 
winds are occurring over the Gulf of California and elsewhere. 
Seas are 4 to 6 ft to the west of Baja California and over the 
southern Gulf of California extending south to Cabo Corrientes, 
with 3 to 5 ft seas elsewhere.

A weakening cold front will cross Baja California tonight into 
Tue. In the wake of the front, winds will strengthen to strong 
in the northern Gulf of California overnight into early Tue.

Looking ahead, gale force gap winds are likely to develop in the
Gulf of Tehuantepec by Fri night.

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

Moderate NE to E winds are noted within and downstream of the 
Papagayo region and Gulf of Panama. Light to gentle winds prevail
elsewhere. Sea heights are in the 5-7 ft range over and downwind
of both the Gulf of Papagayo and Gulf of Panama. Seas range
between 4 to 6 ft elsewhere. Fresh NE winds will continue to 
pulse across the Papagayo region through mid-week, with highest 
winds expected during the overnight hours. Seas associated with 
these winds will be 5 to 7 ft. Fresh north winds in the Gulf of 
Panama will pulse at night through Tue, with seas in the 5-7 ft 
range also. Light to gentle winds, with seas in the 3 to 6 ft 
range, will prevail elsewhere through mid week.

REMAINDER OF THE AREA...

Surface ridge prevails across the area. The pressure gradient 
in the area is supporting moderate to fresh winds north of the 
ITCZ to near 18N and west of 115W. Seas in this area are in the 
8-10 ft range. A cold front extends from 30N121W to 27N130W, then
becomes stationary to 27N140W. Fresh to strong northeasterly 
winds prevail northwest of the front. The front will continue 
moving east across the waters north of 25N through Tue while 
weakening. The front has ushered in a new set of large NW swell 
into the area, with seas peaking near 13 ft over the far NW 
waters. This swell will move through the northern waters into Tue
night while slowly subsiding subside. Another cold front will 
enter the NW waters on Wed. This front will usher in another set 
of NW swell into the NW waters, peaking near 13 ft once again on 
Thu.
