Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Tue Mar 3 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
1400 UTC.

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

A surface trough is noted from 01S81.5W to 03.4S84W and
continuing S of the area, then to 02S109W. The ITCZ extends from
00N111W to 02N125W to beyond 01N140W. Scattered moderate
convection is noted from 00.5S to 03.4S between 92W and 103W, and
from 04N to 06.5N between 122W and 134W.

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

Strong winds and seas of 6 to 8 ft prevail over the Gulf of
Tehuantepec. High pressure is building SE toward Baja
California, causing fresh to locally strong NW winds offshore
Baja California Norte. Elsewhere, a weak pressure gradient is
leading to light to gentle winds, except gentle to moderate in
the northern Gulf of California due to the high pressure.
Moderate seas prevail elsewhere over the open waters off Mexico,
with slight seas over the Gulf of California.

For the forecast, the pressure gradient between high pressure
over NE Mexico and the equatorial trough will support strong gap
winds in the Gulf of Tehunatepec early this morning and again
tonight, then moderate to fresh Wed night and Sat night. High
pressure will build and tighten over the waters N of Punta
Eugenia by Wed, tightening the pressure gradient and supporting
fresh to strong NW winds and building seas off Baja California.
Rough to very rough seas will then persist there through the end
of the week and into the weekend.

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

Strong gap winds are in the Papagayo region, with fresh to strong
gap winds also ongoing in the Gulf of Panama, extending southward
to 03N. Seas in these areas are 5 to 8 ft. Elsewhere, winds are
light to gentle with slight to moderate seas. Scattered moderate
convection is noted SW of the Galapagos Islands and near the
coasts of Ecuador and Colombia.

For the forecast, pulsing fresh to strong winds are expected in
the Papagayo area through through the week and into the weekend.
Winds will increase to tonight into Wed morning, with seas
building to 8 to 9 ft downwind of the Papagayo region to near
90W. Fresh N gap winds and moderate seas will pulse in the Gulf
of Panama and just S of the Azuero Peninsula. Looking ahead, a
significant southerly swell event with rough seas may approach
the waters offshore Ecuador to the Galapagos Islands early next
week.

...REMAINDER OF THE AREA...

High pressure centered just N of the region is dominating much
of the waters N of 10N. This is leading to mainly moderate or
weaker NE to E winds N of the Equator along with moderate seas.

For the forecast, high pressure will build southward over the
area through mid-week, tightening the pressure gradient and
increasing winds. Fresh to locally strong NE winds and rough
seas are likely over NW waters N of 05N and W of 115W starting
late Wed and continuing into the weekend.
