Expect fresh to strong winds along the Baja California coast and parts of the Gulf of California through Mon night as the pressure gradient tightens along the peninsula. Low pressure is centered about 270 nm southwest of Puerto Angel, Oaxaca, and conditions are forecast to be conducive for gradual development. A tropical depression is expected to form by the middle of the week as the system moves W to WNW, well S of mainland Mexico.

There is a medium chance of tropical formation within 48 hours, but a high chance within in the next 7 days. $$ PMZ009-040400- Mexico Border S to 29N within 60 nm of shore- 851 AM PDT Sun Sep 3 2023 .TODAY...NW winds 10 to 15 kt.
