000 FZPN27 KNHC 210857 OFFPZ7 Offshore Waters Forecast NWS National Hurricane Center Miami, FL 157 AM PDT Mon Aug 21 2023 Offshore Waters Forecast for the E Pacific within 250 nm of Mexico Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. PMZ001-212100- Synopsis for the E Pacific within 250 nm of Mexico 157 AM PDT Mon Aug 21 2023 .SYNOPSIS...Fresh to strong gap winds are active across the Gulf of Tehuantepec this morning, due in part to lower pressure over the tropical eastern Pacific. These northerly gap winds will pulse mainly at night across the Gulf of Tehuantepec through Fri. Farther north, winds and seas are diminishing over the northern Gulf of California and off the Baja California peninsula as the remnants of Hilary continue to move well north of the area and dissipate. Looking ahead, another area of low pressure may develop off southern Mexico through mid- week. Any tropical development of this system, if any, should be slow to occur while it moves slowly toward the northwest or north- northwest, possibly supporting fresh winds and rough seas off western Oaxaca and Guerrero by Fri. $$ PMZ009-212100- Mexico Border S to 29N within 60 nm of shore- 157 AM PDT Mon Aug 21 2023 .TODAY...SE to S winds 10 kt in the morning, becoming variable winds less than 5 kt.
