Synopsis for the E Pacific within 250 nm of Mexico
138 AM PDT Fri Oct 22 2021

.SYNOPSIS...A gale warning is in effect for developing low
pressure centered approximately 220 nm south of Acapulco, Mexico.
Showers and thunderstorms near the low are becoming better
organized, and there is a high chance a tropical depression will
form over the next couple of days. Regardless of development,
mariners can expect gales and rough seas in the offshore waters from
western Oaxaca to Michoacan through Mon. Farther north, NW swell
in excess of 8 ft moving into the offshore waters of Baja 
California Norte will subside later today. However, another set 
of large NW swell will follow tonight, reach as far south as 
Socorro Island by Sun, then subside through late Mon. Looking 
ahead, a third round of NW swell may reach Baja California Norte 
waters Mon, reaching Socorro Island by Tue night.
