Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

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

A surface trough extends from 07N78W to 04N102W. The ITCZ 
extends from 04N102W to 05N126W to beyond 04N140W. A second ITCZ
extends from 03S87W to 03S100W to 03S111W. Scattered moderate 
isolated strong convection is noted from 02N to 08N between 130W 
and 139W and from 02S to 03.4S between 89W and 99W. 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...

Moderate to fresh gap winds are diminishing in the Gulf of
Tehuantepec. Moderate S winds have developed in the northern-most
Gulf of California, flowing toward low pressure over southern
California. Elsewhere, mainly gentle winds dominate. Moderate
seas prevail, except for slight seas in the Gulf of California. 

For the forecast, moderate to fresh SW winds in the northern 
Gulf of California will increase to fresh to strong by this 
evening before diminishing by early Wed. Moderate to fresh winds 
will pulse near Cabo San Lucas and near Cabo Corrientes at times 
through mid-week. Moderate to fresh NW winds will dominate 
offshore Baja California by the end of the week as high pressure 
builds W of the peninsula. Moderate seas will dominate the 
offshore through the remainder of the week, except building 
locally to rough off Baja California Norte Fri through 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 8 ft. Moderate N-NE winds 
prevail from the Gulf of Panama southward to around 04N. 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 92W through early Wed
with locally rough seas, with winds becoming moderate to fresh 
thereafter. In the Gulf of Panama, moderate N-NE winds will 
continue to pulse to fresh into tonight. 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 stalling cold front is noted from 31N131W to 21N140W. This
front has has disrupted the usual pressure gradient over the
basin, and thus winds are mainly light to gentle across regional
waters. Seas are generally moderate.

For the forecast, gentle to moderate winds will dominate the open
waters through Wed 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 will continue otherwise 
through mid-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.
