Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Fri Apr 17 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
0200 UTC.

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

A surface trough extends from near the Panama/Colombia border at
07N78W to 09N100W to 03N124W. The ITCZ continues from 03N124W to
04N133W to 01N140W. Scattered moderate and isolated strong 
convection is noted from 01N to 08N between 85W and 96W, from 08N
to 10N between 98W and 100W, from 10N to 13N between 104W and
110W, from 01N to 06N between 112W and 115W, and from 00N to 05N
between 117W and 122W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Strong SW winds will affect the Gulf of California N of 30N 
tonight and more so on Fri night in response to a cold front 
passing through Fri evening. A High pressure ridge W of Baja 
California will weaken and shift SE through Sun in response to 
another cold front approaching from 30N140W. Otherwise, gentle to
moderate NW winds are expected west of Baja California, with 
light to gentle winds prevailing elsewhere. 

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

Winds will pulse to fresh to strong at night across the Papagayo
region through Fri night due to a high pres ridge N of the 
Caribbean. 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 pressure of 1025 mb centered just N of the area 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 high
shifts SE in advance of a cold front entering the NW corner of 
the discussion area. Gentle to moderate winds are expected 
elsewhere for the next several days.

Wave heights range between 6 and 7 ft between 05N and 20N and W 
of 120W, except up to 8 ft along and near 140W, and 4 to 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 pressure to the N to cause seas 
N of 10N and W of 130W to build to between 8 and 9 ft Mon and 
Tue.
