The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0550 UTC. ...TROPICAL WAVES... A tropical wave is just S of Tehuantepec with axis near 94W, extending from 05N to 16N, and moving westward at 10 kt. Scattered to isolated moderate convection from 03N to 15N between 92W and 103W. A tropical wave extends from 05N to 17N with axis near 111W, moving westward at 10-15 kt. Numerous moderate to strong convection is from 04N to 15N between 104W and 120W. A tropical wave extends from 06N to 17N with axis near 132W, moving westward at 15-20 kt. Scattered moderate to strong convection is from 02N to 16N between 120W and 138W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N83W to 09N96W. The ITCZ begins near 09N96W to 10N109W, then resumes near 09N115W to 09N129W, then resumes near 09N134W to 09N140W. For information on convection, see the Tropical Waves Section above. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Fresh to strong winds and moderate to locally rough seas are over the Gulf of Tehuantepec. Moderate or weaker winds, and moderate seas, prevail elsewhere, except in the Gulf of California where winds are light to gentle and seas are slight. For the forecast, fresh to strong gap winds and rough seas are expected across the Gulf of Tehuantepec into the weekend. Elsewhere, a moderate pressure gradient will support mostly gentle to moderate winds across the offshore waters of Mexico. The pressure gradient between high pressure NW of the area and lower pressure over the Colorado River Valley will support fresh southerly winds across the northern Gulf of California late this weekend into early next week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to near gale-force winds are across and downstream of the Gulf of Papagayo to nearly 89W. Seas of 7 to 8 ft accompany the plume of gap winds. In the Gulf of Panama, moderate to fresh N winds extends to 06N. Moderate seas in the 4 to 5 ft are over this region. Otherwise, moderate easterlies from the Papagayo gap wind event extends across the Guatemala and El Salvador outer offshores where seas are 5-6 ft. Elsewhere, light to gentle winds prevail along with moderate seas in SW swell. For the forecast, fresh to strong gap winds and occasional rough seas will pulse across the Gulf of Papagayo into early next week. Moderate or weaker winds and moderate seas in SW swell are expected across the remainder of the waters through the period, except for large SE to S swell near the Galapagos early next week. ...REMAINDER OF THE AREA... A 1027 mb high near 37N138W extends a ridge across the subtropical E Pacific waters to nearly 115W. The gradient of pressure between this area of high pressure and a tropical wave with axis near 132W is supporting moderate to fresh NE to E winds from 12N to 25N W of 130W. Seas over these waters are 7-8 ft. Rough seas to 8 ft are found over the waters S of 03N between 113W and 128W. Elsewhere, gentle to moderate winds and moderate seas prevail. For the forecast, seas to 8 ft in the western tradewind waters will subside by Sat. Farther south, southerly swell to 8 ft will impact the waters south of 05N and west of 100W through the weekend. Otherwise, showers and thunderstorms associated with the tropical wave near 132W may further organize, likely resulting in the development of a tropical depression early next week as this system moves westward toward the central Pacific. Also, an area of low pressure could form well offshore of the SW coast of Mexico early or into the middle of next week. Some gradual development of this system is possible thereafter as it moves generally west-northwestward. $$ Ramos --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC080401_C_KWBC_20260808040138_47448518-392-TWDEP.txt ****0000004394**** AXPZ20 KNHC 080401 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Sat Aug 8 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 0910 UTC. ...TROPICAL WAVES... A tropical wave is SW of Tehuantepec with axis near 97W, extending from 05N to 15N, and moving westward at 15-20 kt. Scattered to isolated moderate convection is from 03N to 11N between 92W and 100W. A tropical wave extends from 06N to 16N with axis near 114W, moving westward at 15 kt. Numerous moderate to strong convection is from 06N to 15N between 107W and 116W. A tropical wave extends from 01N to 18N with axis near 134W, moving westward at 15-20 kt. Scattered moderate to strong convection is from 01N to 16N between 123W and 139W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N84W to 08N90W to 09N93W. The ITCZ begins near 09N96W to 10N103W to 10N110W, then resumes near 09N114W to 08N130W. Aside from the convection associated with the tropical waves, scattered moderate convection is from 05N to 18N between 100W and 107W, and from 06N to 15N between 117W and 125W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... An earlier scatterometer pass confirmed fresh to strong NNE winds in the Gulf of Tehuantepec, reaching about 13N. Rough seas in the 8-9 ft range are present with the strongest winds. Moderate easterlies are ongoing S of 13N, in the Tehuantepec and Oaxaca outer offshore waters along with moderate seas to 7 ft. High pressure of 1027 mb near 38N139W extends a ridge SE to the Baja California offshore waters, which is supporting gentle to moderate NW winds off the Baja Peninsula along with 4-5 ft seas. Light to gentle winds prevail elsewhere with slight seas, except moderate seas in SW swell over the remainder SW offshores. For the forecast, fresh to strong gap winds and rough seas are expected across the Gulf of Tehuantepec through late Sun. The pressure gradient between high pressure NW of the area and lower pressure over the Colorado River Valley will support fresh to locally strong southerly winds across the southern and northern Gulf of California Sat night into Mon. Elsewhere, a moderate pressure gradient will support mostly gentle to moderate winds across the remainder offshore waters of Mexico. Looking ahead, a tropical wave currently SW of Tehuantepec will move west and reach the Revillagigedo Islands adjacent waters Mon evening through Wed evening, bringing fresh winds and shower activity to the region. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong NE to E winds are across and downstream of the Gulf of Papagayo to nearly 90W. Seas of 7 to 8 ft accompany the plume of gap winds. In the Gulf of Panama, moderate to locally fresh N winds extends to 06N. Moderate seas in the 4 to 5 ft are over this region. Otherwise, moderate easterlies from the Papagayo gap wind event extends across the Guatemala and El Salvador outer offshores where seas are 5-6 ft. Moderate southerly winds are also across the Ecuador offshores with moderate seas to 5 ft. Light to gentle winds prevail elsewhere along with moderate seas in SW swell. For the forecast, fresh to strong NE to E gap winds will prevail in the Papagayo region through Wed, reaching near gale-force briefly tonight through late Sun as the Bermuda High shift southward E of the area, thus increasing the pressure gradient over the SW Caribbean. The gap wind event will produce a fetch of moderate to locally fresh easterlies across the outer offshore waters of Guatemala and El Salvador. Moderate or weaker southerly winds and moderate seas will continue across the offshores between Ecuador and the Galapagos through the forecast period. Moderate northerly winds will pulse in the Gulf of Panama at night through Tue evening. Light to gentle winds and moderate seas in SW swell are forecast elsewhere through Wed night. ...REMAINDER OF THE AREA... A 1027 mb high near 37N139W extends a ridge across the subtropical E Pacific waters to nearly 115W. The gradient of pressure between this area of high pressure and a tropical wave with axis near 134W is supporting moderate to fresh NE to E winds from 09N to 20N W of 130W. Seas over these waters are 7-8 ft. Rough seas to 8 ft are found over the waters S of 02N between 120W and 128W. Elsewhere, gentle to moderate winds and moderate seas prevail. For the forecast, seas to 8 ft in the western tradewind waters will subside today. Farther south, southerly swell to 8 ft will impact the waters south of 02N and west of 120W through the weekend. Otherwise, showers and thunderstorms associated with the tropical wave near 134W may further organize, likely resulting in the development of a tropical depression early next week as this system moves westward toward the central Pacific. Also, an area of low pressure could form well offshore of the southwestern coast of Mexico early or into the middle of next week. Some gradual development of this system is possible thereafter as it moves generally west-northwestward. $$ Ramos ########################### END OF MESSAGE SET ############################
