Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Sat Mar 21 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 08N81W to 05N86W. The ITCZ extends
from 05N86W to beyond 04N140W. Scattered moderate convection is 
noted from 05N to 08N between 115W and 133W.

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

High pressure in eastern Mexico is beginning to weakening and
move east, relaxing the pressure gradient between it and the
equatorial trough. Thus, gales have ended in the Gulf of
Tehuantepec. However, strong NE gap winds continue. Moderate NW
winds have developed offshore Baja California as another high
pressure builds in from the N Pacific. Elsewhere, a weak 
pressure gradient is generating light to gentle winds. Moderate 
seas prevail over the open waters, with slight seas in the Gulf 
of California.

For the forecast, the strong gap winds in the Gulf of Tehuantepec
will diminish Sun. Moderate to locally fresh NW winds will 
dominate offshore Baja California. Moderate to locally fresh SE 
winds will pulse Sun night in the Gulf of California as low 
pressure deepens to the north. Otherwise, light to gentle winds 
will dominate the basin. Long period N swell will arrive Sun 
offshore Baja California Norte, and this will likely lead to 
rough seas there Sun late night into early next week. 

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

Fresh gap winds are ongoing in the Gulf of Papagayo and Gulf of 
Panama, with light to gentle winds elsewhere. Seas are 3 to 5 ft,
except for 5 to 7 ft seas offshore Guatemala due to gap winds N 
of the region in the Gulf of Tehuantepec as well as in the
Papagayo region.

For the forecast, strong winds will pulse nightly in the Gulf of
Papagayo through at least Mon night, with moderate to locally
fresh winds pulsing in the Gulf of Panama during this time. 
Gentle breezes and moderate seas will prevail elsewhere. 

...REMAINDER OF THE AREA...

The pressure gradient between high pressure centered N of the
area and the ITCZ is leading to gentle to moderate trades from 
the equator to 18N, with gentle trades to the S. Dominated by 
the ridge, waters N of 18N are experiencing gentle anticyclonic 
winds. Seas through the basin are 4 to 7 ft.

For the forecast, moderate or weaker winds and moderate seas 
will generally prevail across the region through the start of 
next week. N swell will build just S of 30N from off Baja 
California Norte Sun, leading to rough seas into Sun night.
