Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1030 UTC Sat Mar 14 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 0600 UTC surface analysis and satellite imagery through
0800 UTC.

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

A surface trough is located from 10N86W to 05N93W to 01N104W.
The ITCZ continues from 01N104W to 04N120W to 02N140W.
Scattered moderate convection is noted from 08N to 10N between 
120W and 123W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A low pressure trough is located from Baja California Norte SW
for approximately 300 nm. This trough will move E and weaken,
gradually dissipating later this morning, as high pressure 
builds over the region. Ahead of the trough, fresh S to SW winds 
will prevail across the far N Gulf of California will diminish 
later this morning. Moderate to fresh NW winds are expected 
through the weekend over the southern Gulf of California, 
southward to Cabo Corrientes. Winds will increase to fresh to  
strong while becoming SW in the northern Gulf of California Mon 
night ahead of another trough diminishing early Tue, with yet 
another round Wed night.

Elsewhere from Cabo Corrientes to Puerto Angel, tranquil marine 
conditions generally will prevail through the weekend.

Across the Gulf of Tehuantepec, variable winds and slight seas 
are expected through this evening before northerly gap winds 
spill across the Gulf late tonight into Sun morning, and peaking
near 30 kt. Similar conditions are possible late Sun night into 
Mon morning.

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

Fresh NE to E winds will continue across the Gulf of Papagayo 
region into next week, with nocturnal winds pulsing to around 25
kt across much of the area.

Fresh northerly winds will continue across the Gulf of Panama 
and downstream to 05N through early next week, briefly increasing
to strong Mon night.

REMAINDER OF THE AREA...

N of the ITCZ, moderate to occasionally fresh NE tradewinds will
prevail W of 120W and S of 17N through the weekend, with seas in
the area of 6 to 8 ft in N to NW swell.

Looking ahead, model guidance suggests a significant low 
pressure system will develop offshore of California over the 
weekend and dive southward to near 31N by mid week, producing a 
significant increase in northerly swell and the potential for 
gale force winds associated with low pressure sweeping into the 
NE waters late Wed or Thu.
