Tropical Weather Discussion
NWS National Hurricane Center Miami FL
745 UTC Mon Apr 6 2020

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
0840 UTC.

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

A trough extends from 07N78W to 05N91W. The ITCZ continues from 
05N91W to 04N110W to 07N124W to beyond 05N140W. Scattered 
moderate isolated strong convection is noted from 03N to 06N 
between 86W and 98W. Scattered moderate isolated strong 
convection is noted from 04N to 06N between 112W and 118W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface ridge extends from west of the forecast area to just 
offshore of Baja California Sur. The pressure gradient between 
this ridge and a surface trough over the Gulf of California is 
supporting gentle to moderate N-NW winds off the Baja California.
Fresh to strong S to SW winds persist across northern portion of
the Gulf of California, while winds are light and variable 
across the remainder of the Gulf. Elsewhere, light to gentle NW 
to W winds prevail across the remaining Mexican waters from Cabo 
Corrientes to the Gulf of Tehuantepec. Seas of 4 to 5 ft prevail 
across the open waters off Baja California and SW Mexico.

A cold front will approach Baja California and the Gulf of 
California through Tue night. Fresh to locally strong SW winds 
will pulse across the northern Gulf of California ahead of the 
front tonight and Tue night, while winds off of Baja California 
Norte gradually shift W to SW. High pressure will build in the 
wake of the front midweek. 

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

Moderate to fresh winds re pulsing across the Gulf of Papagayo,
and gentle to moderate winds prevail over the Gulf of Panama.
Elsewhere, light to gentle winds prevail. SW swell is propagating
across the southern waters, with seas in the 6-7 ft range between
the Galapagos Islands and Ecuador. Seas in the 3-5 ft range 
prevail elsewhere. A western Caribbean high pressure ridge will 
build southward through Wed. The resultant pressure gradient will
support fresh to strong NE to E gap winds across the Gulf of 
Papagayo region. Long-period SW swell prevailing across the 
southern waters will subside through midweek. 

REMAINDER OF THE AREA...

A cold front is moving across the far northern waters. A narrow 
south of the front to just offshore of Baja California Sur. The 
pressure gradient between the ridge and lower pressure in the 
vicinity of the ITCZ is supporting mainly gentle to moderate 
tradewinds N of the ITCZ to 22N and W of 120W, where seas of 5-7
ft prevail.

The cold front will continue to move slowly ESE across the 
waters N of 25N through Tue, while a weak ridge will prevail S 
of the front. This setup will support gentle to moderate winds, 
and seas in the 4-7 ft range over the forecast waters N of the 
ITCZ through Tue. Fresh trade winds will return late Tue through 
mid week as high pressure builds in the wake of the front.
