Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1330 UTC Mon Apr 29 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

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

A trough extends from 09N84W to 05.5N93W. The ITCZ continues 
from 05.5N93W to 06N120W, then resumes from 05N128W to beyond 
02N140W. Scattered moderate isolated strong convection was noted
from 04N to 07N E of 87W. Scattered moderate isolated strong 
convection was noted within 150 nm N of the ITCZ between 97W and 
115W. Scattered moderate to strong convection was noted from 05N 
to 08N between 121W and 128W, and from 03N to 06N W of 128W. 

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 

High pressure extends SE to just west of the Revillagigedo 
Islands. The pressure gradient between the area of high pressure
and a surface trough across the Gulf of California is supporting 
gentle to moderate NW to N winds over the offshore waters of Baja
California with seas in the 4-5 ft range. These conditions will 
continue to prevail through the week.

Gulf of California: Fresh to strong S to SW winds across far 
north portions of the Gulf will prevail through early Tue before
diminishing. Light to gentle winds will then prevail across the
Gulf of California through the week. 

Gulf of Tehuantepec: Light to moderate winds and seas of 4 to 6 
ft will prevail through Fri night.

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

Gulf of Papagayo: Fresh to strong NE to E winds over the Gulf of 
Papagayo region will diminish Wed night.

Gulf of Panama: Fresh N winds over the Gulf of Panama will 
become light to moderate Tue afternoon. 

Ongoing agricultural burning, which are normally carried on 
during this time of year in SE Mexico and in Central America, is 
generating smoke leading to hazy conditions along and adjacent 
to the coast of Central America and the coast of SE Mexico, 
including the Gulf of Tehuantepec region. 

REMAINDER OF THE AREA...

High pressure prevails over the northern waters. The pressure
gradient between the area of high pressure and lower pressure in
the vicinity of the ITCZ is supporting moderate to fresh
tradewinds N of the ITCZ to near 20N and west of 120W. Combined
seas of 6-8 ft prevail over these waters in a mic of NW and SW 
swell. These conditions will prevail through the remainder of
the week. 

N swell is producing seas of 8 ft N of 29N between 123W and 132W.
Seas will subside below 8 ft by midweek. Cross- equatorial SW 
swell will propagate through much of the forecast area east of 
120W Thu afternoon through Sat. Combined seas of 8 ft or higher 
will generally be confined to the waters south of the 02S and 
west of 95W.
