NWS National Hurricane Center Miami FL
1005 UTC Wed Mar 20 2019

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.

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

A surface trough extends from 09N79W to 07N90W. The ITCZ 
continues from 07N90W to 03N110W to beyond 04N140W. Scattered 
moderate isolated strong convection is noted from 04N to 08N 
between 81W and 97W.

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...  

Gulf of Tehuantepec: Strong winds over the Gulf of Tehuantepec 
will pulse to near gale-force during the overnight hours through 
Fri night with the additional component of drainage flow. Seas 
will peak near 12 ft during the period of strongest winds.

Gulf of California: A weak cold front will approach the northern 
Gulf of California from today. S to SW gap winds will strengthen 
to around 20 kt with the passage of the front. 

Light to gentle winds prevail elsewhere over the open waters. NW 
swell will propagate into the waters off the Baja California 
Norte coast today, then spread southward across the rest of the 
Baja Peninsula, with seas greater than 8 ft or greater expected 
over this area by Thu, before starting to gradually subside. 

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

Gulf of Papagayo: Winds will pulse to strong during the overnight
hours across the Gulf of Papagayo through the forecast period.

Gulf of Panama: Northerly winds will freshen over the Gulf of 
Panama Thursday night through Sun night.

Between Ecuador and the Galapagos Islands, 5-7 ft seas in SW 
swell will persist through Thu. Elsewhere, light to moderate 
winds and 3-5 ft seas will prevail for the next several days. 

REMAINDER OF THE AREA... 

A cold front extending from 30N119W to 20N129W has ushered in a 
large set of NW swell into the area. Seas are currently peaking 
near 14 ft over NW waters. The swell will continue to propagate 
SE across the waters while subsiding the next couple of days. By 
Thu afternoon, seas 8 ft or greater will cover most of the area 
W of 110W.

Elsewhere, moderate to fresh trade winds prevail mainly S of 18N 
and west of 116W to the ITCZ. High pressure building behind the 
front will bring a slight increase to the trades today. Another 
cold front will approach from the northwest toward the end of 
the week, ushering in another set of large long period NW swell.
