--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-06-22 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC220403_C_KWBC_20260622040412_32440682-3504-TWDEP.txt ****0000004506**** AXPZ20 KNHC 220403 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Mon Jun 22 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 0350 UTC. ...TROPICAL WAVES... A tropical wave is along 90W, south of 16N, moving westward at 15-20 kt. Scattered moderate to isolated strong convection is present from 03N to 13N between 82W and 94W. A tropical wave is along 97W, south of 15N, drifting westward at 5-10 kt. Scattered moderate convection is active from 05N to 09N and between 94W and 100W. A tropical wave is along 106W, south of 16N, moving westward at 5-10 kt. Scattered moderate convection is observed from 07N to 13N between 100W and 110W. A tropical wave is along 122W, south of 17N, drifting westward at 5 kt. No significant convection is evident near this wave. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 13N110W to 09N125W. The ITCZ extends from 09N125W and beyond 08N140W. Aside from the convection associated with the tropical waves, scattered moderate convection is evident in the Gulf of Panama and from 07N to 12N between 109W and 118W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to fresh NW winds are across the Baja California offshore waters along with 5-7 ft seas. The strongest winds are N of Cabo San Lazaro. Elsewhere, light to gentle winds and slight to moderate seas prevail. For the forecast, ridging over the eastern Pacific will support moderate to fresh NW winds off Baja California through Mon night, and gentle to moderate breezes elsewhere. Winds off Baja California will diminish starting Tue as the high pressure weakens ahead of a trough moving into the area from off southern California. This pattern will also support moderate to fresh southerly winds across the Gulf of California Tue ahead of the trough. Looking ahead, expect fresh to strong northerly gap winds and rough seas across the Gulf of Tehuantepec by midweek, as pressure lowers farther south into the tropics. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... A small plume of 15 kt easterly gap winds and seas to 5 ft are evident across the Gulf of Papagayo region, extending downstream to 88W. Farther south, moderate southerly winds and moderate seas are occurring south of 03N. Elsewhere, light to gentle winds and slight to moderate seas prevail. For the forecast, moderate to fresh easterly trade winds and moderate seas are expected in the Papagayo region into early next week. Winds will reach fresh to strong speeds starting late Mon with seas building to 9 ft by late Tue. The gap winds in the Gulf of Tehuantepec will produce seas to 9 ft in the far offshore waters of Guatemala by midweek. Meanwhile, mainly moderate southerly winds and moderate to locally rough seas will prevail across the offshore waters between Ecuador and the Galapagos Islands through at least midweek. ...REMAINDER OF THE AREA... The subtropical ridge centered well north of our waters extends into the remainder of the tropical eastern Pacific north of 20N. Gentle to moderate NE to E winds and moderate seas are found north of 10N and west of 115W. Farther south, long period SW swell with wave heights of 7-9 ft are moving into the waters south of 02N between 106W and 120W. Elsewhere, moderate or weaker winds and moderate seas prevail. For the forecast, additional pulses of SW swell will continue to propagate across the forecast waters east of 125W generating moderate to locally rough seas. Otherwise, little changes are expected in winds and seas through early next week as a ridge remains in control of the weather pattern across the area. Looking ahead, a low pressure system is expected to form late this week several hundred miles offshore of the coast of southwestern Mexico. Some slow development of this system is possible after that time while it moves west-northwestward at 10 to 15 kt. $$ Ramos ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC220949_C_KWBC_20260622095003_9109880-6609-TWDEP.txt ****0000004883**** AXPZ20 KNHC 220949 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Mon Jun 22 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 0600 UTC surface analysis and satellite imagery through 0920 UTC. ...TROPICAL WAVES... A tropical wave is along 90W, south of 16N, moving westward at 15-20 kt. Scattered moderate to isolated strong convection is present from 03N to 14N between 83W and 94W. A tropical wave is along 97W, south of 15N, drifting westward at 5-10 kt. Scattered moderate convection is active from 06N to 11N and between 94W and 101W. A tropical wave is along 106W, south of 16N, moving westward at 5-10 kt. Scattered moderate convection is observed from 06N to 13N between 104W and 110W. A tropical wave is along 125W, south of 17N, drifting westward at 5 kt. No significant convection is evident near this wave. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 12N110W to 09N125W. The ITCZ extends from 09N125W and beyond 08N140W. Aside from the convection associated with the tropical waves, scattered moderate convection is evident offshore Panama and Colombia, from 07N to 14N between 110W and 118W, and from 04N to 10N W of 130W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to fresh NW winds are across the Baja California offshore waters along with 5-6 ft seas. The strongest winds are N of Cabo San Lazaro. In the southern Gulf of California, winds are gentle to moderate from the SE and seas are slight. Elsewhere, light to gentle winds and slight to moderate seas prevail. For the forecast, ridging over the eastern Pacific will support moderate to fresh NW winds off Baja California through tonight, and gentle to moderate breezes elsewhere. Winds off Baja California will diminish starting Tue as the high pressure weakens ahead of a trough moving into the area from off southern California. This pattern will also support moderate to fresh southerly winds across the Gulf of California Tue ahead of the trough. Looking ahead, expect fresh to strong northerly gap winds and rough seas across the Gulf of Tehuantepec by midweek, as pressure lowers farther south into the tropics. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh NE to E gap winds and seas to 5 ft are evident across the Gulf of Papagayo region, extending downstream to 90W. Farther south, gentle to moderate southerly winds and moderate seas are occurring between Ecuador and the Galapagos Islands. Elsewhere, light to gentle winds and slight to moderate seas prevail. For the forecast, moderate to fresh easterly trade winds and moderate seas are expected in the Papagayo region through today. Winds will reach fresh to strong speeds starting tonight with seas building to 9 ft by late Tue. The gap winds in the Gulf of Tehuantepec will produce seas to 9 ft in the far offshore waters of Guatemala by midweek. Meanwhile, mainly moderate southerly winds and moderate to locally rough seas will prevail across the offshore waters between Ecuador and the Galapagos Islands through Fri. ...REMAINDER OF THE AREA... The subtropical ridge centered well NW of our waters extends across the eastern Pacific waters north of 20N. Gentle to moderate NE to E winds and moderate seas are found from 10N to 20N west of 115W. Farther south, long period SW swell with wave heights of 7-9 ft are moving into the waters south of 03N between 101W and 120W. Elsewhere, moderate or weaker winds and moderate seas prevail. For the forecast, additional pulses of SW swell will continue to propagate across the forecast waters east of 125W generating moderate to locally rough seas. Otherwise, little changes are expected in winds and seas through early next week as a ridge remains in control of the weather pattern across the area. Looking ahead, a tropical wave a few hundred miles off the coast of southwestern Mexico is forecast to move westward at 10-15 kt across the central and western portion of the basin, and some slow development is possible toward the end of the week. Also, a low pressure system is expected to form late this week several hundred miles offshore of the coast of southwestern Mexico. Some slow development of this system is possible after that time while it moves west-northwestward at 10-15 kt. $$ Ramos ########################### END OF MESSAGE SET ############################
