Tropical Weather Discussion
NWS National Hurricane Center Miami FL
017 UTC Thu Apr 9 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 0000 UTC surface analysis and satellite imagery through
0240 UTC.

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

A trough extends from 08N82W to 06N90W. The ITCZ continues from
06N90W to 04N124W to 05N140W. Scattered moderate isolated strong
convection was noted from 03N to 07N between 105W and 135W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure prevails west of the Baja California peninsula.
Fresh to strong winds prevail off Baja California Sur. Gentle to
moderate winds prevail off the coast of Baja California Norte.
Light to gentle winds prevail elsewhere. Seas are in the 5-7 ft
range over the open waters off Mexico, and 1-3 ft over the Gulf 
of California. 

High pressure will build west of the Baja California peninsula.
This will strengthen winds from Baja California Sur southward to
near Cabo Corrientes through the end of the week. Seas over this
area will build to 8 ft. Winds and seas will decrease by early
this weekend.

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

Fresh to strong winds prevail over the Gulf of Papagayo. Moderate
to fresh winds prevail over the Gulf of Panama. Elsewhere, light
to gentle winds prevail. Seas over the Gulf of Papagayo are in
the 6-7 ft range. Outside the Gulf of Papagayo, wave heights are
in the 5-6 ft range. Winds will diminish over the Gulf of
Papagayo. Thursday.

Moist southerly flow is expected to gradually increase over the
forecast waters as large scale conditions become favorable for
enhanced convection Thursday through the middle of next week. 
These ingredients appear favorable to possibly promote locally 
heavy rainfall over sections of southern Costa Rica, Panama, 
western Colombia and northwest Ecuador during this time period.

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 an area of fresh to 
strong northeast to east trades from about 08N to 16N and 
between 115W and 130W. Wave heights within this area of fresh to
strong winds are in the 8-10 ft range. Moderate to fresh 
northeast to east trades are elsewhere from 08N to 25N and west 
of 115W, where wave heights are in the 6-8 ft range. Elsewhere, 
trade winds are in the gentle to moderate range, with wave 
heights of 5-7 ft. Winds will start to diminish slightly Fri as 
the area of high pressure weakens slightly and loosens the 
pressure gradient.
