PMZ001-171945- Synopsis for the E Pacific within 250 nm of Mexico 1243 AM PDT Tue Oct 17 2023 .SYNOPSIS...Showers and thunderstorms associated with an area of low pressure located a few hundred miles offshore of the southwestern coast of Mexico are gradually becoming better organized. Environmental conditions are conducive for further development of this system, and a tropical depression is very likely to form today. This system is expected to move slowly west- northwestward and then turn northwestward or northward late in the week offshore of the coast of southwestern Mexico. This system has a high chance of tropical cyclone development in the next 48 hours. A gale warning is in effect for this system beginning this afternoon. Elsewhere, gale- force gap winds will prevail over the Gulf of Tehuantepec through Wed morning. Fresh to strong winds will continue to pulse over the Tehuantepec region through the remainder of the week. Rough to very rough seas can be expected over this area through Wed. Gentle to moderate winds west of the Baja California peninsula and over Gulf of California will continue through tonight before diminishing. Fresh to strong winds offshore Baja California may develop this weekend. Large NW swell is forecast to spread offshore Baja California by the end of the week into the weekend. $$ PMZ009-171945- Mexico Border S to 29N within 60 nm of shore- 1243 AM PDT Tue Oct 17 2023 .TODAY...W to NW winds 10 kt.
