Tropical Weather Discussion
NWS National Hurricane Center Miami FL
114 UTC Mon Mar 30 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
0300 UTC.

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

A surface trough extends from 08N84W to 07N95W. The ITCZ 
continues from 07N95W to 06N120W to beyond 04N140W. No 
significant convection is noted at this time.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface ridge extends from the north-central Pacific toward the
offshore forecast waters of Baja California. The pressure gradient
between the ridge and low pressure over central Mexico supports 
an area of fresh to strong NW-N winds N of 26N E of 117W. These 
winds are expected to persist through tonigh with seas building 
to 8 ft. The high pressure will weaken through mid-week allowing
for winds off Baja California to diminish. Gentle west to northwest
winds will dominate the waters between Cabo Corrientes and the
Tehuantepec region through the period, except for a brief pulse 
of fresh to strong northerly winds across the Gulf of Tehunatepec 
early this morning.

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

High pressure north of the western Caribbean will maintain 
fresh to strong NE-E winds in the Gulf of Papagayo region this 
morning, with seas building to 8 ft. Similar marine conditions 
are expected tonight into Tue morning. Fresh northerly winds 
across the Gulf of Panama will continue through this morning. 
Light to gentle winds are expected elsewhere across the offshore 
waters through the middle of the week. 

REMAINDER OF THE AREA...

A broad ridge reaches from west to east north of 25N. This is
supporting a large area of fresh to strong trade wind flow from
about 08N to 20N west of 120W, as noted in various scatterometer
satellite passes and buoy data from the past several hours over 
the deep tropics. Concurrent altimeter satellite data showed 
seas of 8 to 12 ft in the area of fresh to strong winds. These 
are primarily shorter period wave related to the trade wind flow,
but also with components of longer period northerly swell. 
Farther east, light to moderate winds and 4 to 6 ft seas are 
noted over the tropical east Pacific. A surface trough persists 
along 135W near the ITCZ. Scattered showers and isolated 
thunderstorms are ongoing near this trough.

Little change is expected in this pattern through early next 
week. The ridge will weaken into the middle part of the week, 
allowing for winds to diminish and wave heights to subside west 
of 120W.
