PMZ001-041600- Synopsis for the E Pacific within 250 nm of Mexico 900 PM PDT Fri Oct 3 2025 .SYNOPSIS...Showers and thunderstorms continue to become better organized in association with a broad low pressure system located a few hundred miles off the coast of southwestern Mexico. Additional development is expected, and a tropical depression will likely form later tonight or tomorrow. The system is forecast to move very slowly west-northwestward, parallel to but offshore of the southwestern coast of Mexico for the next several days. This system has a high chance for tropical cyclone formation within the next 48 hours. Regardless of development, a gale warning is ongoing in association with this system. Increasing winds and building seas are expected over these waters. Elsewhere, a ridge will continue to dominate the offshore forecast waters of Baja California this weekend supporting moderate to fresh NW to N winds N of Cabo San Lazaro, and gentle to moderate winds between Cabo San Lazaro and Cabo San Lucas. Long period NW swell off Baja California will support moderate to rough seas in the outer waters through late Sat night. Fresh to strong N to NE winds are expected in the Gulf of Tehuantepec tonight into Sat morning. $$ PMZ009-041600- Mexico Border S to 30N within 60 nm of shore- 900 PM PDT Fri Oct 3 2025 .TONIGHT...NW winds 15 to 20 kt N of 31N, and NW to N 15 to 20 kt S of 31N.
