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

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

A surface trough extends from 07N78W to 05N85W to low pressure 
near 10N108W to 06N115W. The ITCZ continues from 06N115W to 
04N130W to 04N130W. Scattered moderate isolated strong 
convection is noted from 00N to 10N between 85W and 99W.
Scattered moderate isolated strong convection is noted from 10N
to 15N between 102W and 110W. Scattered moderate convection is
noted from 01N to 06N between 112W and 126W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure extends west of the offshore waters of Baja
California. Light to gentle winds prevail across the forecast
waters, except to moderate over the northern Gulf of California.
Seas are in the 3-5 ft range over the open waters, 4-5 ft over 
the northern Gulf of California, and 1-2 ft over the remainder of
the Gulf of California. 

Strong SW winds will affect the Gulf of California N of 30N 
tonight into early Sat in response to a cold front passing 
through this evening. A high pressure ridge W of Baja California 
will weaken and shift SE through Sun. Gentle to moderate NW 
winds are expected W of Baja California, with light to gentle 
winds prevailing elsewhere into early next week. NW winds W of 
Baja California will increase to moderate to fresh Tue and Tue 
night as high pressure builds in from the NW. Seas over this area
will build to between 7 and 9 ft.

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. Gentle to
moderate winds prevail elsewhere. Seas are in the 6-8 ft range
over the Gulf of Papagayo, and 2-4 ft elsewhere. 

Winds will pulse to fresh to strong across the Papagayo region 
tonight due to a high pres ridge N of the Caribbean. Light to 
gentle winds will prevail elsewhere. 

REMAINDER OF THE AREA...

A ridge extends from high pressure of 1023 mb centered near
29N142W to near 21N116W. The pressure gradient between this area
of high pressure and lower pressure in the vicinity of the ITCZ
is supporting moderate to fresh winds N of the ITCZ to 20N and
west of 125W. Light to gentle winds prevail elsewhere. Seas are
in the 5-8 ft range N of 05N and W of 120W, and 4-5 ft elsewhere. 

The area of high pressure will maintain moderate to fresh winds 
from 06N to 22N W of 125W until Sat. The high will then weaken,
which will diminish winds in this region. Gentle to moderate 
winds are expected elsewhere for the next several days.

Little change in seas is expected through Sun. Long period NW 
swell will combine with NE wind waves building seas N of 10N and
W of 130W to 8-9 ft Mon. These seas will expand eastward to 120W
on Tue.
