Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1537 UTC Thu Apr 16 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 1200 UTC surface analysis and satellite imagery through
1440 UTC.

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

A surface trough extends from 08N82W to 05N93W to 07N102W to 
03N112W to 04N120W to 01N126W. The ITCZ continues from 01N126W 
to 00N133W to beyond 01N140W. Scattered moderate and isolated
strong convection is noted from 02N to 07N between 87W and 120W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A High pressure ridge W of Baja California will weaken and shift
SE through Sun in response to a cold front approaching from the 
NW. A pulse of fresh N gap winds is expected in the Gulf of 
Tehuantepec this morning. Strong SW winds will affect the Gulf 
of California Fri night in response to a low pres trough over far
NW Sonora. Otherwise, gentle to moderate NW winds are expected 
west of Baja California, with light to gentle winds elsewhere.

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

A high pres ridge N of the Caribbean will cause moderate to 
fresh offshore winds to pulse at night across the Papagayo region
through Fri night. Winds in this region could be locally strong 
tonight. Light to gentle winds will prevail elsewhere. Scattered 
showers and isolated thunderstorms affecting the waters adjacent 
to Costa Rica and Panama will shift E over the waters adjacent to
Colombia by Fri. Boaters navigating the waters in these areas 
should refer to forecasts and statements issued by your local 
meteorological services.

REMAINDER OF THE AREA...

High pres centered near 34N139W will maintain moderate to fresh 
winds between 05N and 20N W of 125W until Sat, then winds in this
region will weaken as the ridge shifts SE in advance of a cold 
front entering the NW corner of teh discussion area. Gentle to 
moderate winds are expected elsewhere for the next several days. 
Wave heights are in the 6-7 ft range S of 20N and W of 115W, and 
4-6 ft elsewhere. Little change in seas is expected through Sun, 
then long period NW swell could combine with trade wind waves 
generated by strengthening high pres to the N to cause seas N of 
10N and W of 130W to build to between 8 and 9 ft Mon and Tue.
