Tropical Weather Discussion

NWS National Hurricane Center Miami FL

2205 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 1800 UTC surface analysis and satellite imagery through

2030 UTC.



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



A surface trough extends from 07N78W to 05N89W. The ITCZ 

stretches from 05N89W to beyond 04N140W. Scattered moderate 

convection is noted near and along the ITCZ and W of 118W. 



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



Moderate to fresh 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, moderate to fresh northerly winds and moderate

seas in the Gulf of Tehuantepec will diminish today. Moderate NW

winds will dominate offshore Baja California. Fresh 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 early on Mon. 

Otherwise, light to gentle winds will dominate the basin. The 

next gap wind event will arrive in the Gulf of Tehuantepec Mon 

night, with pulsing 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 moderate to

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 100W. Another area

of moderate to fresh winds is noted N of 27N and E of 135W.

Moderate seas prevail in this area. 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 continues to build N of the area today, 

leading to rough seas just W of Baja California Norte tonight.
