Individual waves may be more than twice the significant wave height. PMZ001-210430- Synopsis for the E Pacific within 250 nm of Mexico 924 AM PDT Fri Oct 20 2023 .SYNOPSIS...Hurricane Norma is near 19.4N 109.2W at 8 AM PDT, and is moving NNW at 7 kt. Maximum sustained winds are 95 kt with gusts to 115 kt, and the minimum central pressure is 960 mb. Norma will move to 20.6N 109.6W this evening, 22.1N 109.8W Sat morning, 23.3N 109.6W Sat evening, weaken to a tropical storm near 23.9N 109.1W Sun morning, 24.3N 108.3W Sun evening, and inland to 24.7N 107.4W Mon morning. Norma will weaken to a tropical depression while moving inland near 26.0N 106.0W by early Tue. Meanwhile, fresh to strong N winds will continue to pulse over the Tehuantepec region through Sat morning. Fresh to locally strong winds can be expected across the Baja California offshore waters this weekend. Large NW swell is forecast to continue to spread offshore Baja California into the weekend, resulting in confused and hazardous seas as it mixes with swells generated by Norma. Most of the swell will subside by Mon morning. A broad area of low pressure located well south of the Gulf of Tehuantepec is forecast to develop later this weekend, and a tropical depression will likely form by early next week. The system is forecast to meander during the next couple of days and then drift generally northward late this weekend and into early next week. This system has a medium chance of development in 48 hours and high chance in 7 days. $$ PMZ009-210430- Mexico Border S to 29N within 60 nm of shore- 924 AM PDT Fri Oct 20 2023 .TODAY...NW winds 15 to 20 kt in the afternoon.
