PMZ001-152130- Synopsis for the E Pacific within 250 nm of Mexico 227 AM PDT Tue Aug 15 2023 .SYNOPSIS...Moderate to fresh NW winds are expected offshore the coast of Baja California from Punta Eugenia to Cabo San Lazaro mainly at night through the next few days. Fresh to strong gap winds in the Gulf of Tehuantepec will spread southwestward this morning merging with the cyclonic circulation associated with the potential tropical cyclone EP90. This system is producing widespread showers and thunderstorms off the southern coasts of Mexico, Guatemala, and El Salvador. Environmental conditions appear conducive for development, and a tropical depression is expected to form within the next two days or so, while the system moves west-northwestward, roughly parallel to the coast of southern and southwestern Mexico. Looking ahead, another area of low pressure could form south of the Gulf of Tehuantepec over the weekend. Some gradual development of this system is possible thereafter while it moves generally westward. $$ PMZ009-152130- Mexico Border S to 29N within 60 nm of shore- 227 AM PDT Tue Aug 15 2023 .TODAY...NW winds 10 to 15 kt.
