Synopsis for the E Pacific within 250 nm of Central America,
Colombia, and within 750 nm of Ecuador
332 PM PDT Wed Apr 8 2020

.SYNOPSIS...The pressure gradient between high pressure north of
the area and a surface trough over the equatorial waters will
support fresh to strong northeast to east gap winds across the
Gulf of Papagayo region through Thu, mainly during the overnight
hours. Deepening moist southerly flow south of the equatorial
trough in combination with an upper-level disturbance forecast
to move across the eastern Pacific during the next few days
could lead to increasing chances for scattered showers and
thunderstorms over the offshore waters primarily south of 09N.
