--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-04-24 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC240251_C_KWBC_20260424025157_47448518-1816-TWDEP.txt ****0000002724**** AXPZ20 KNHC 240251 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Fri Apr 24 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 0000 UTC surface analysis and satellite imagery through 0240 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough axis extends from 09N78W to 06N90W to 07N100W, where it transitions to the ITCZ and continues to 09N115W to 03N140W. Scattered moderate to strong convection is from 10N to 12N between 115W and 125W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Broad ridging over the eastern Pacific west of Baja California is maintaining moderate to locally fresh NW winds along the coast of Baja California, gentle breezes across the Gulf of California and farther south off southern Mexico. Seas are 5-7 ft off Baja California, 1-3 ft over the Gulf of California, and 3-5 ft elsewhere. For the forecast, the high pressure over the region will generally maintain moderate to fresh northwest winds over the Baja California waters, with little change in conditions expected into early next week. Northwest swell offshore Baja California will subside a little tonight allowing for seas to lower to just below 8 ft. Elsewhere, mostly light to gentle west to northwest winds are expected through Mon. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle variable winds prevail north of the equator, with 2-4 ft seas. Moderate to fresh SE winds and 5-7 ft seas in S to SW swell prevail south of the equator. Little change is expected for the forecast through early next week. ...REMAINDER OF THE AREA... Broad high pressure north of 20N is supporting moderate to fresh NE winds from 05N to 15N west of 125W, where combined seas are 7-9 ft primarily in N swell. The pattern supports gentle to moderate winds and 4-6 ft seas elsewhere w of 110W, and light breezes with 4 ft combined seas in S to SW swell east of 110W. For the forecast, the rather weak high pressure across the region will generally maintain moderate to fresh trade winds from the ITCZ to 20N and west of 120W. Once the aforementioned north swell decays, seas will be in the range of 6 to 7 ft over the western part of the area through Sat, then 5 to 6 ft across the entire area into early next week. $$ Christensen ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC240811_C_KWBC_20260424081202_49676782-1848-TWDEP.txt ****0000002840**** AXPZ20 KNHC 240811 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Fri Apr 24 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 2145 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough axis extends from low pressure over western Colombia to the coast at 07N78W to 09N91W to 07N102W to 07N116W, where it transitions to the ITCZ to 07N126W to 05N135W to beyond 04N140W.

Broad ridging over the eastern Pacific west of Baja California is generally maintaining moderate to locally fresh northwest winds over the offshore waters of Baja California. Latest altimeter satellite data passes indicate seas of 4 to 6 ft in long-period northwest swell over these waters. Inside the Gulf of California, light to gentle southeast winds are over its northern portion while light and variable winds are elsewhere across the Gulf. Seas are 2 to 3 ft in the Gulf, except for slightly higher seas of 3 to 4 ft in the central portion and 3 to 5 ft in the southern portion due to a long-period south to southwest swell. For the forecast, the high pressure over the region will generally maintain moderate to fresh northwest winds over the Baja California waters well into next week. A tightening pressure gradient between high pressure northwest of the region shifting eastward, with a ridge extending southeastward across the Baja California offshore waters and low pressure over the western U.S. will induce fresh to strong southwest to west gap winds across the northern Gulf of California Sat night into Sun. Elsewhere, mostly light to gentle west to northwest winds are expected through early next week. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle variable winds prevail north of the equator along with seas of 3 to 4 ft. Moderate to fresh southeast winds along with seas of 5 to 7 ft in long-period south to southwest swell continue south of the equator. For the forecast, a light gradient will maintain rather tranquil conditions over the Central American and Colombian waters well into next week while moderate to fresh southeast winds and moderate long-period south to southwest swell remain offshore Ecuador. ...REMAINDER OF THE AREA... The gradient related to broad high pressure north of about 19N is generally supporting gentle to moderate trades from 05N to 15N west of 125W, where combined seas are 7 to 9 ft primarily in long-period north swell. Gentle to moderate north to northeast winds are north 09N between 115W and 122W, and gentle to moderate northeast to east winds are from 07N to 18N between 122W and 140W, except for an area of moderate to fresh northeast to east winds from 25N to 27N between 135W and 140W as seen in a recent scatterometer satellite data pass. The gradient is a bit tighter over this part of the area, where a trough is located near 135W. Seas of 8 ft in decaying north swell are over the area from 06N to 14N between 133W and 139W per an altimeter satellite data pass. Seas elsewhere are 4 to 6 ft primarily in northwest swell. Patches of light to moderate quickly moving eastward are noted north of 25N between 132W and 138W. For the forecast, the rather weak high pressure across the region will generally maintain moderate to fresh trade winds from the ITCZ to 20N and west of 120W. Once the aforementioned north swell decays tonight, seas will be in the range of 6 to 7 ft over the western part of the area through Sat, then 5 to 6 ft across the entire area into early next week. $$ Aguirre ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC242308CCA_C_KWBC_20260424230909_49676782-1888-TWDEP.txt ****0000004404**** AXPZ20 KNHC 242308 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 2205 UTC Fri Apr 24 2026 Corrected Remainder of the Area 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.
