Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Mon Mar 9 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 0000 UTC surface analysis and satellite imagery through
0350 UTC.

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

A surface trough extends from 09N86W to 04N94W to 01N103W. The 
ITCZ is analyzed from 00N108W to 03S127W to 01N140W. Scattered 
moderate convection is noted from 01N to 06N between 80W and 99W. 

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

A 1008 mb low is over the outer offshore waters of Baja
California Norte near 27N119W with a trough extending NE to
30N118W and SW to 25N121W. To the west of the low, a broad
surface ridge prevails, which is tightening the pressure gradient
and supporting fresh to strong W to NW winds over the western
semicircle of the low, extending to approximately 125W from the
low center. Rough seas to 9 ft are within these winds. In the Gulf 
of California, winds are moderate or weaker from the S to SW due
to the presence of a surface trough. Moderate to locally fresh NW
winds are offshore Jalisco with moderate seas to 5 ft in NW
swell. Light to gentle winds and slight to moderate seas prevail
elsewhere.

For the forecast, the aforementioned low will slowly move east
and reach Punta Eugenia by Mon evening before dissipating over
the Gulf of California Mon night into Tue. Fresh to strong winds
and rough seas associated with this low will continue to affect 
the offshore waters between Cabo San Lazaro and Punta Eugenia 
through Mon night. By Tue, a ridge will rebuild toward Baja 
California as set of NW swell just crosses 30N near 120W. The 
pressure gradient between the ridge and lower pressure over 
Mexico will support fresh NW winds between Los Cabos and Cabo 
Corrientes, including Las Marias Islands Tue night into Wed. 
Strong winds across the Tehuantepec region will pulse on Mon 
morning and continue through the evening hours. The next gap wind
event in the Tehuantepec region may be possible on Thu, with 
winds increasing to gale force in the wake of a Gulf of America 
cold front. 

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

Fresh to strong NE to E winds and moderate seas are in the Gulf 
of Papagayo region and downwind from the Gulf to near 88W, while 
moderate to fresh N winds and slight to moderate seas are in the
Gulf of Panama and downstream to 06N. Light to gentle winds and 
slight seas are elsewhere.

For the forecast, fresh to strong winds are expected in the 
Papagayo region nightly and into the mornings through the week 
as high pressure remains N of the region. Gentle to moderate N 
winds are forecast in the Gulf of Panama this week. Mainly light
to gentle winds will prevail elsewhere through early next week. 
Cross-equatorial S to SW swell is expected to reach the offshore 
waters between Ecuador and the Galapagos Islands on Tue, 
building seas to rough, except in the lee of the Galapagos 
Islands. 

...REMAINDER OF THE AREA...

Strong high pressure of 1031 mb is centered well to the NW of 
the region near 37N146W. Associated broad ridging covers the 
waters N of about 20N and W of 124W. The related pressure 
gradient is sustaining moderate to fresh NE winds N of 07N W of 
130W. Rough seas to 9 ft prevail with these winds. Elsewhere, 
winds are of moderate or weaker speeds. Seas across the remainder
of the open waters are moderate in mixed swell, except for rough
seas in NE swell N of 08N and W of 130W.

For the forecast, the aforementioned strong high pressure will 
continue to dominate the majority of the western and central 
waters N of 15N and W of 120W through midweek while it weakens 
slightly. Ridging will rebuild toward Baja California by Tue as a
set of NW swell just crosses 30N between 120W and 130W.
