Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2104 UTC Sun Apr 12 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 1800 UTC surface analysis and satellite imagery through
2045 UTC.

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

A surface trough extends from 07N78W to 06N102W to 02N123W. The 
ITCZ extends from 02N124W to 02N135W to 02N140W. Scattered 
moderate to strong convection is noted from 02N TO 10N east of 
99W. Scattered moderate convection is south of the equator
between 87W and 100W, and from 02N to 09N between 101W and 124W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Latest scatterometer data show a gentle to moderate NNW breeze
along the offshore waters of Baja California, the southern half
of the Gulf of California to the adjacent waters of Manzanillo,
Mexico. Seas across these waters range between 4 to 7 ft except
for the central and southern Gulf of California where seas are up
to 4 ft. Surface ridging west of Baja California will continue to 
support these conditions through Wed with winds reaching fresh
speed at night over the coastal waters off the Baja peninsula.
The pressure gradient in the region will weaken afterwards and 
will support mainly light to locally moderate winds west of Baja
California through Fri. A surface trough will move across the 
northern Gulf of California tonight supporting moderate to fresh 
SW winds with seas to 5 ft. Otherwise, light to gentle winds, 
and seas to 7 ft will prevail over the remainder of the open 
waters off SW and southern Mexico through Fri.

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

Gentle to moderate gap winds continue in the Gulf of Papagayo 
and the Gulf of Panama with seas ranging between 4 to 6 ft. 
Light to gentle winds prevail elsewhere with seas to 5 ft.

Moist S to SW flow will gradually increase over the forecast 
area through the middle of next week, and large scale 
atmospheric conditions will be favorable for enhanced widespread
convection. Conditions will be favorable for locally heavy 
rainfall to persist over the waters near the equatorial trough 
axis, and shift eastward into southern Costa Rica, Panama, 
western Colombia and northwest Ecuador during the next several 
days. Please refer to forecasts and statements issued by your 
local meteorological services.

Fresh to strong winds are expected to pulse at night in the Gulf
of Papagayo beginning Mon night and continuing through Fri
morning. Gentle to locally moderate southerlies will remain 
across the remainder offshore waters through Fri. Otherwise, long
period cross-equatorial S-SW swell will move continue to move into
the regional waters through Thu.

REMAINDER OF THE AREA...

A strong surface ridge continue to dominate the Pacific open
waters N of 10N. The most recent scatterometer data show mainly
moderate to locally fresh NE to E winds north of the equatorial 
trough and the ITCZ to 20N and west of 110W. Latest altimeter
data show seas in this region range between 4 to 7 ft. The
surface ridge will prevail through the end of the upcoming week,
thus supporting similar conditions. 

Otherwise, widespread active convection occurring along and 
north of the equatorial trough will continue through the middle
of the week, as large scale conditions are favorable for deep 
convection across much of the tropical northeast Pacific E of 
120W.
