Tropical Weather Discussion

NWS National Hurricane Center Miami FL

1605 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 1200 UTC surface analysis and satellite imagery through

1500 UTC.



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



A surface trough extends from 08N77W to 05N87W. The ITCZ 

stretches from 05N87W to beyond 04N140W. Scattered moderate 

convection is noted along the ITCZ and W of 115W. 



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



Fresh to strong northerly winds prevail in the Gulf of 

Tehuantepec. These winds are associated with a moderate pressure 

gradient between a 1020 mb ridge in the Gulf of America and 

lower pressures in the deep tropics. Moderate seas prevail in 

these waters. Elsewhere, a broad subtropical ridge located well 

northwest of the area supports 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 this morning. 

Moderate to fresh NW winds will dominate offshore Baja 

California. Moderate to 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 rough 

seas. Moderate to 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 fresh easterly winds and 

moderate seas from the ITCZ to 20N and west of 110W. Farther 

east, moderate to fresh easterly winds and moderate seas 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.
