928 AXPZ20 KNHC 172100 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 1605 UTC Fri Apr 17 2026 Corrected Offshore Waters Within 250 nm of Mexico section 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 1545 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from northwest Colombia southwestward to the coast of Colombia near 07N77W, and continues to 08N86W to 05N96W to 06N108W to a 1012 mb low near 04N110W and to 02N114W. The ITCZ begins at 06N112W and continues to 04N124W to 05N130W and to beyond 04N140W. Scattered moderate convection is within 60 nm south of the trough between 97W-104W. Similar activity is within 120 nm north of the ITCZ between 131W-135W, also within 60 nm south of the ITCZ between 127W-130W, and within 30 nm of the ITCZ between 112W-115W. A southern- hemispheric ITCZ extends from 02S87W to 02S106W to 04S121W to 03S130W and to beyond 03S140W. Scattered moderate convection is within 60 nm north of the ITCZ between 87W-91W, within 30 nm of the ITCZ between 103W-107W, and within 30 nm of the ITCZ west of 136W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...Corrected A surface ridge extends from 30N125W to 20N117W to 15N108W. The related gradient is allowing for northwest moderate to fresh winds west of the Baja California peninsula. Southwest winds in the northern Gulf of California have diminished to fresh speeds. Elsewhere over the Pacific and the Gulf of California, winds are moderate or weaker in speeds. Seas are 5 to 7 ft in northwest swell over Pacific waters northwest of Cabo Corrientes, 5 to 6 ft in south swell over the Pacific to the southeast of Cabo Corrientes, 3 to 4 ft in the Gulf of California, except for seas of 4 to 6 ft in the southern section and slightly higher seas of 5 to 7 ft in long-period south swell at the entrance to the Gulf. No deep convection is occurring over the Mexican offshore waters. For the forecast, fresh to strong northwest winds will occur near Cabo San Lucas through early Sat. Additionally, large northwest swell will impact the Pacific waters west of Baja California Norte today through Sat. Elsewhere, quiescent conditions will remain over the Mexican offshores through the weekend. Looking ahead, high pressure building over the Gulf of America is expected to induce a strong to near gale Tehuantepec gap wind event beginning Sun night into Tue. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh northeast to east winds are in the Gulf of Papagayo region. These winds reach westward to near 89W as indicated in a recent scatterometer satellite data pass. Elsewhere, winds across the Central American and equatorial waters are moderate or weaker. Seas over the forecast waters are 5 to 6 ft in long-period south to southwest swell. Isolated moderate convection is observed from 03S to 07S between 85W and 89WW near the Galapagos Islands. For the forecast, rather tranquil conditions are expected to remain over the Central American and the equatorial waters through early next week. ...REMAINDER OF THE AREA... High pressure of 1025 mb is analyzed north of the area at 33N137W, with a ridge extending from it through 30N125W to 20N117W and to near 15N108W. The weak pressure gradient between the ridge and lower associated to the ITCZ is allowing for only moderate to locally fresh northeast trades over forecast waters. Seas are 5 to 7 ft in mixed swell. No additional deep convection is occurring away from the surface trough/ITCZ. For the forecast, little change is expected in the winds during the next few days. Large northwest swell will impact waters north of 28N and east of 125W today through Fri night. Otherwise, little change in the seas are also expected through the weekend. Looking ahead, a cold front is expected to reach the northwest part of the discussion our NW corner at 30N140W early on Sun. The frontal boundary should move eastward while gradually weakening, accompanied by large northwest to north swell. The swell should reach near 20N and west of 130W by Tue. $$ Aguirre  198 AXPZ20 KNHC 172124 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 1605 UTC Fri Apr 17 2026 Corrected Offshore Waters Within 250 nm of Mexico section 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.

A high pressure ridge axis extends from 30N128W to 24N120W and to near the Revillagigedo Islands. A dissipating cold front dropping southeastward is analyzed from a triple point located over the California/northern Baja border at 35.5N117W, south- southwest from there to 27N117W, to 24.5N122W and to near 26129W. No significant winds and convective activity is present with this front. The pressure gradient in place is allowing for northwest moderate to fresh winds west of the Baja California peninsula.
