PMZ101-120900- Synopsis for the E Pacific within 250 nm of Central America, Colombia, and within 750 nm of Ecuador 155 PM PDT Tue Jun 11 2024 .SYNOPSIS...Monsoonal winds, associated seas and scattered to numerous thunderstorms will dominate the region this week. Low pressure is expected to develop across portions of the Yucatan Peninsula, the Bay of Campeche, and western portions of Central America Wed and Thu. This will induce the monsoon trough to lift farther northward toward the Gulf of Tehuantepec, with winds to the west of 90W increasing to fresh to locally strong, leading to building seas to 10 ft. Look for thunderstorm activity to also increase during this time. Fresh to strong SW winds are expected to develop south of Panama Fri and shift into the Gulf of Panama Fri night and Sat. Moderate southerly swell will reach the Galapagos Islands Thu night and the regional offshore waters Fri night. $$ PMZ111-120900- Guatemala and El Salvador to 250 nm offshore- 155 PM PDT Tue Jun 11 2024 .TONIGHT...S to SW winds 10 to 15 kt.
