Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Sun Mar 22 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 0600 UTC surface analysis and satellite imagery through
0855 UTC.

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

A surface trough extends from 08N82W to 05N92W. The ITCZ 
stretches from 05N92W to 03N120W and beyond 04N140W. Scattered 
moderate convection is observed from 05N to 10N and west of 
110W.

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

A recent scatterometer satellite pass captured fresh to strong
northerly winds in the Gulf of Tehuantepec. These winds are
associated with a moderate pressure gradient between a 1019 mb
ridge in the Gulf of America and lower pressures in the deep
tropics. Seas in these waters are 5-8 ft. Elsewhere, a broad 
subtropical ridge located well northwest of the area support 
moderate to fresh northerly winds and moderate seas in the 
offshore waters of Baja California. In the remainder of the 
basin, moderate or weaker winds and slight to moderate seas 
prevail.

For the forecast, the strong northerly winds and rough seas in
the Gulf of Tehuantepec will diminish quickly today. Moderate to
locally fresh NW winds will dominate offshore Baja California. 
Moderate to locally strong SE winds will pulse tonight into Mon 
in the Gulf of California as low pressure deepens to the north. 
Seas will increase to 8 ft west of Guadalupe Island tonight and 
diminish Mon. Otherwise, light to gentle winds will dominate the 
basin. The next gap wind event will arrive in the Gulf of 
Tehuantepec Mon night, supporting strong to near gale N winds 
and rough seas into late this week.

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

A broad subtropical ridge centered north of the Caribbean Sea 
supports fresh to strong easterly trade winds and moderate seas 
across the Gulf of Papagayo, extending downstream to 90W. 
Farther east, a tight pressure gradient forces fresh northerly 
winds and moderate seas across the Gulf of Panama, extending 
south to 03N. Elsewhere, light to gentle winds and moderate seas
are prevalent.

For the forecast, strong NE-E winds will pulse nightly in the 
Gulf of Papagayo through much of the week, along with locally 
rough seas. Moderate to locally fresh N winds will pulse in the 
Gulf of Panama during this time. Gentle breezes and moderate seas
will prevail elsewhere. 

...REMAINDER OF THE AREA...

The broad high pressure positioned north of the tropical eastern
Pacific waters supports moderate to locally fresh easterly winds
and moderate seas from the ITCZ to 20N and west of 110W. Farther
east, moderate to locally fresh easterly winds and seas of 5-7 
ft are noted north of the ITCZ and east of 105W. Elsewhere, 
moderate or weaker winds and moderate seas prevail.

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 today, leading to rough seas into tonight.
