Tropical Weather Discussion

NWS National Hurricane Center Miami FL

2205 UTC Mon Apr 22 2024



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

2000 UTC.



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



A surface trough extends from 08N78W to 06N91W. The ITCZ 

continues from 06N91W to 06N115W to beyond 02N140W. Scattered 

moderate convection is noted from 03N to 09N E of 88W, and from 

05N to 10N between 110W and 130W. 



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



A surface ridge extends W of the Baja California peninsula to

near the Revillagigedo Islands. The pressure gradient between 

this area of high pressure and a trough over the Gulf of

California is supporting gentle to locally moderate winds west 

of the Baja California peninsula. The pressure gradient between 

high pressure over the eastern slopes of Mexico and the 

equatorial trough is supporting fresh to strong winds in the 

Gulf of Tehuantepec. Light to gentle winds prevail elsewhere. 

Seas are in the 7-9 ft range in the Gulf of Tehuantepec, 4-6 ft 

over the remainder of the open waters off Mexico, and 3 ft or 

less over the Gulf of California.



For the forecast, gentle to moderate winds winds and moderate 

seas will persist west of the Baja California peninsula through 

the middle of this week. Winds will then freshen Thu and Fri. 

Fresh to strong gap winds in the Gulf of Tehuantepec will 

continue through Tue before diminishing. Seas will peak near 10 

ft tonight with the gap winds. Elsewhere, light to gentle winds 

and moderate seas will prevail. 



...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, 

AND WITHIN 750 NM OF ECUADOR



Light to gentle winds and seas of 4-6 ft prevail across most of 

the discussion waters except off Ecuador, where seas are peaking 

near 7 ft.



For the forecast, light to gentle breezes will persist across 

the region through the week. Wave heights will be mostly 4 to 6 

ft primarily in SW swell, except 6 to 7 ft off Ecuador through 

tonight. Moderate to occasionally fresh gap winds will develop in

the Gulf of Papagayo Tue, then continue through the week. 



...REMAINDER OF THE AREA...



High pressure prevails over the waters N of 20N. The pressure 

gradient between the area of high pressure and lower pressure in 

the vicinity of the ITCZ is supporting moderate to fresh trade 

winds from 05N to 15N between 120W and 140W, where seas are in 

the 7-9 ft range. Elsewhere gentle to locally moderate winds are

noted across the discussion waters. Aside from the seas in the

tradewind zone mentioned above, seas are in the 4-6 ft range. 



For the forecast, wind speeds and wave heights will remain 

similar through the week, with an area of 7-9 ft seas persisting

roughly from 08N to 12N W of 130W. A weak surface low will enter

the north- central portion of the discussion waters by mid- week

locally enhancing winds/seas.
