A tropical wave is noted along 94W, extending from 05N into Southern Mexico, moving W at 10 kt. Scattered moderate convection has developed from 05N to 15N between 90W to 100W. A tropical wave has entered the Eastern Pacific extending from 06N into Panama, moving W at 10 to 15 kt. A 1008 mb low is observed E of the wave axis. Numerous moderate to strong convection is noted from 04N to the coast of Panama between 77W to 83W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from the coast of Colombia near 05N77W to a 1008 mb low pressure near 05N78W, then it continues west to 08N100W to T.D. Ten-E and SW to 15N115W. The monsoon trough resumes W of Hurricane Hilda near 13N123W to a 1008 mb low pressure near 12N127W, then the monsoon trough ends near 09N132W. Convection in the vicinity of the monsoon trough is primarily associated with features described in the Special Features and Tropical Wave sections above, except scattered moderate convection from 06N to 12N between 99W to 105W, and from 07N to 11N between 85W to 90W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... See Special Features section above for information on low pressure well south of southern Mexico that has a high chance of tropical formation in the next 48 hours. Surface ridge extends from a 1033 mb high near 37N146W southeastward to 17N124W. NE to N winds over the Gulf of Tehuantepec are fresh to strong. Elsewhere winds are moderate or weaker across the Mexican offshores and the Gulf of California. Seas are 4-6 ft across the Mexican offshores and 1-3 ft over the Gulf of California. For the forecast, high pressure over the Gulf of Mexico and lower pressure farther to the south will continue to support fresh to locally strong pulses of N gap winds across the Gulf of Tehuantepec this afternoon. Newly formed Tropical Depression Ten-E will bring strong winds and higher seas near its path to waters well offshore Michoacan, Colima, and Jalisco, as well as near the Revillagigedo Islands. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Fresh NE to E gap winds are occurring in the Papagayo region with winds moderate or weaker elsewhere. Seas are 4-6 ft across the Central American and equatorial offshore zones. For the forecast, fresh NE to E gap winds will continue today over the Papagayo region. Elsewhere, quiescent winds should prevail into late week. SW swell will build combined seas to 6-8 ft over the equatorial waters before relaxing on Mon. REMAINDER OF THE AREA... See the Special Features section above for details on newly- upgraded Hurricane Hilda and Tropical Depression Nine-E. Surface ridging extends from a 1033 mb high near 37N146W southeastward to 17N124W. NE trades south of the ridge and north of the monsoon trough are generally moderate or weaker, except in the vicinity of the two tropical cyclones with fresh winds. South of the monsoon trough S to SW winds are moderate or weaker. Seas are generally 4-6 ft, except for seas 6-8 ft south of the equator and east of 120W due to SW swell. Winds and seas over some sections of the area will be impacted by the two tropical cyclones detailed in the Special Features during the next several days. $$ Torres
