Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Sun Mar 8 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
2015 UTC.

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

A surface trough extends from 08N85W to 04N92W to 03N102W. The 
ITCZ is analyzed from 02N104W to beyond 02N140W. Scattered 
moderate convection is noted along the trough and ITCZ mainly E 
of 120W.

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

Strong high pressure of 1034 mb is centered well to the NW of 
the forecast area near 37N144W. A broad ridge extends 
southeastward from the high toward the Revillagigedo Islands. 
Latest scatterometer satellite data and nearby surface 
observations suggest that a broad low of 1010 mb is centered near
28N118W, with trough extending from 30N118W to the low to 
25N118W. Fresh to strong winds and rough seas prevail across the
northern semicircle of the low, while light to gentle winds and 
moderate seas are elsewhere over the offshore forecast waters of
Baja California. Light winds and slight seas prevail across the 
Gulf of California. Elsewhere over the Mexican offshore waters, 
including the Gulf of Tehuantepec, light winds and moderate seas
in S to SW swell are present.

For the forecast, the aforementioned low will slowly move east- 
northeastward through early week while dissipating. The 
tightening pressure gradient between this low and the ridge to 
the W will induce fresh to strong winds and building seas to 
around 8 ft within 240 nm of the low center. Winds and seas will 
diminish by Mon night as the low moves inland Mexico. 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 89W, while
gentle to moderate N winds and moderate seas are in the Gulf of 
Panama and downstream to 05N. Light to gentle winds and moderate seas
in long-period S to SW swell 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 1034 mb is centered well to the NW of 
the region near 37N144W. Associated broad ridging covers the 
waters N of about 15N and W of 115W. The related pressure 
gradient is sustaining fresh N to NE winds N of 28N W of 130W. 
Rough seas 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.
