Tropical Weather Discussion

NWS National Hurricane Center Miami FL

2205 UTC Wed Apr 23 2025



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

2130 UTC.



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



The monsoon trough enters the Pacific along the coast of Panama 

near 09N79W and extends to 09N84W to 05N101W. The ITCZ continues 

from 05N101W to 06N123W to beyond 02N140W. A second ITCZ has been

analyzed from 01S118W to beyond 06S140W. Widely scattered 

moderate convection is occurring from 04N to 07N east of 88W, and

from 03N to 09N between 107W and 140W. 



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



Locally fresh W to NW winds are pulsing off the southern tip of 

the Baja California Peninsula near Cabo San Lucas, along the 

southern end of a trough extending through the Gulf of 

California. Locally moderate S winds prevail in the northern Gulf

of California, with associated seas of 1 to 3 ft. Otherwise, 

recent scatterometer satellite data show gentle to moderate NW 

winds over the remainder of the waters offshore of Baja and 

southwestern Mexico, and seas of 4 to 7 ft.



For the forecast, fresh NW winds will pulse in the bays offshore

of Baja California and near Cabo San Lucas each night and 

morning into this weekend. Pulsing fresh to locally strong SW 

winds can also be expected in the northern Gulf of California. 

Looking ahead, fresh to locally strong NW winds are anticipated 

offshore of Baja this weekend as a tightening pressure gradient 

develops ahead of a cold front moving southward along the 

California coast. Locally rough seas may accompany the winds. 

Elsewhere, occasional fresh to strong N winds will develop in the

Gulf of Tehuantepec this weekend. 



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

AND WITHIN 750 NM OF ECUADOR...



Prevailing low pressure over the south-central Caribbean is 

supporting moderate to fresh E winds and seas of 5 to 7 ft in the

Gulf of Papagayo. Elsewhere, moderate or weaker winds and 

moderate seas in S to SW swell prevail over the remainder of the 

regional waters. 



For the forecast, fresh to locally strong E winds and locally 

rough seas are expected each night and morning in the Gulf of 

Papagayo through Fri morning, with winds pulsing to fresh speeds 

this weekend. Elsewhere, pulsing moderate to locally fresh N 

winds will be possible in the Gulf of Panama into early next 

week. Looking ahead, a long-period S to SW swell will move into 

the waters offshore of Ecuador this weekend, leading to locally 

rough seas near the Galapagos Islands. 



...REMAINDER OF THE AREA....



A 1029 mb high centered north of the area near 37N143W extends 

ridging through the eastern Pacific waters north of the monsoon 

trough and ITCZ. Recent scatterometer satellite data depict 

moderate to fresh NE to E winds between 05N to 20N west of 120W. 

Altimeter satellite data show wave heights over 8 ft in this 

region. Farther north, moderate N to E winds prevail on the 

periphery of the high pressure, and seas of 5 to 7 ft are noted 

in this region as seen from SOFAR buoy data. South of the ITCZ, a

long-period S to SW swell is promoting localized seas to 8 ft 

south of the equator and west of 115W.



For the forecast, moderate N to E winds will occur north of the 

ITCZ and monsoon trough through this weekend as high pressure 

prevails across the eastern Pacific. Winds will pulse to fresh 

speeds from 05N to 20N west of 120W through Fri, and rough seas 

will occur in tandem with these winds. Fresh winds will expand 

farther north to 30N this weekend as a weakening cold front 

drifts southward through the northern waters. Elsewhere, a long- 

period Southern Hemisphere swell will produce rough seas south of

the equator Thu night through Sat.
