Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Tue Mar 31 2026

Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.

Based on 1800 UTC surface analysis and satellite imagery through
1930 UTC.

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

A surface trough extends from 07N78W to 05N97W. The ITCZ extends
from 05N97W to 05N123W to beyond 05N140W. A second ITCZ extends 
from 03S88W to 03S102W to 03S120W. Scattered moderate isolated 
strong convection is noted from 02N to 08N between 130W and 
139W. Scattered moderate convection is noted from 03N to 06N 
between 86W and 93W and from 06N to 09N between 95W and 104W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Fresh S winds are increasing in the northernmost Gulf of
California, flowing into low pressure over southern California.
Elsewhere, mainly gentle winds dominate, although some moderate
NW winds are ongoing near Cabo Corrientes and Cabo San Lucas. 
Moderate seas prevail, except for slight seas in the Gulf of 
California. 

For the forecast, fresh S to SW winds in the northern Gulf of
California will increase to fresh to strong this evening, then
diminish by Wed morning. Moderate to fresh winds will continue
pulsing near Cabo Corrientes and Cabo San Lucas into Wed night. 
Fresh NW winds will dominate offshore Baja California Thu and 
Fri as high pressure builds W of the peninsula. NW swell will
bring locally rough seas off Baja California Norte Fri into Sat
night. 

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

Fresh to locally strong NE-E winds prevail over the Papagayo 
region, with seas building to around 7 ft. Moderate N-NE winds 
prevail from the Gulf of Panama southward to around 06N. Winds 
are light to gentle elsewhere. Slight seas are offshore 
Colombia, with moderate seas elsewhere.

For the forecast, fresh NE-E winds will pulse to strong across 
and downwind of the Papagayo region to near 90W tonight, with 
winds becoming moderate to fresh thereafter. Large S-SW swell 
will spread into the waters from offshore Ecuador to the 
Galapagos Islands by Wed morning, and reach the remaining area 
waters and Central American coasts Thu. This swell will build 
seas to rough from offshore Ecuador to the Galapagos Islands 
through Thu.

...REMAINDER OF THE AREA...

A stationary front extends from 31N131W to 21N140W. Weak high
pressure is centered just NW of the Revillagigedo Islands. An
overall modest pressure gradient between these two features and
the ITCZ to the south is leading to widespread light to gentle
winds through the basin, with mainly moderate seas. 

For the forecast, gentle to moderate winds will dominate the open
waters into Wed night as weak high pressure across much of the 
area slowly builds into the Baja California waters. A series of 
weak frontal boundaries will move into the NW waters and weaken W
of 130W throughout the week. Moderate seas generally will 
continue into late week, large southerly swell will move into 
the waters S of the Equator into Wed, reach 10N Thu, then 
gradually subside. The pressure gradient may tighten N of 05N and
W of 110W by the end of the week increasing trades to moderate 
to locally fresh, with seas building locally to rough as a 
result. Northerly swell may build seas to rough just S of 30N by 
late Thu night into the weekend.
