Tropical Weather Discussion

NWS National Hurricane Center Miami FL

0405 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 0000 UTC surface analysis and satellite imagery through

0200 UTC.



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



A surface trough extends from 08N79W to 05N93W. The ITCZ 

continues from 05N93W to beyond 05N140W. Scattered moderate 

convection is noted from 03N to 08N W of 122W. Scattered showers

are noted along the trough. 



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



A surface ridge extends from a high pressure centered well N of

the area to the Revillagigedo Islands. The pressure gradient 

between this area of high pressure and a trough western Mexico is

supporting gentle to moderate winds west of the Baja California 

peninsula. Light to gentle winds prevail elsewhere. Seas are in 

the 4-6 ft range over 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 locally freshen Thu and 

Fri. Fresh to strong gap winds will develop in the Gulf of 

Tehuantepec late tonight, and continue through Tue before 

diminishing. Seas will peak near 10 ft Mon night 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 the 

discussion waters.



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, building to 5 to 7 ft off Ecuador tonight.

Moderate to occasionally fresh gap winds will develop in the 

Gulf of Papagayo Tue, then continue through the week. 



...REMAINDER OF THE AREA...



A high pressure is centered well N of the area, with ridge 

extending SE to near the Revillagigedo Islands. 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 20N between 120W and 140W, where seas are in 

the 7-9 ft range. A surface trough is over the NW waters from 

30N133W to 26N139W. Moderate winds and seas of 6-7 ft are west 

of the frontal boundary. Gentle to moderate winds are noted N of 

28N between 120W and 128W where the pressure gradient is locally 

tighter between the ridge and trough over the Gulf of California.

Gentle winds are noted elsewhere across the discussion waters. 

Aside from the areas mentioned above, seas are in the 4-6 ft 

range. 



For the forecast, wind speeds and wave heights will remain 

similar into early this week, with an area of 8 ft seas 

persisting roughly from 08N to 12N W of 130W with N swell mixing 

with NE wind waves. The trough will dissipate tonight. Looking 

ahead, a weak surface low will enter the north-central portion of

our waters by mid-week enhancing winds/seas.
