PMZ101-161000- Synopsis for the E Pacific within 250 nm of Central America, Colombia, and within 750 nm of Ecuador 247 PM PDT Sun Jun 15 2025 .SYNOPSIS...Large S to SW swell dominating the regional waters will slowly subside through early next week. Tropical Storm Dalila is weakening and will turn more W tonight through Tue, moving away from the Mexican coast and expected to dissipate Tue night. Low pressure offshore NW Costa Rica is expected to drift W to W-NW through the middle of next week. Environmental conditions appear conducive for gradual development of the low, and a tropical depression is likely to form by the middle of this coming week while moving westward to west-northwestward and just offshore of the coasts of El Salvador, Guatemala, and southeastern Mexico. Showers and thunderstorms are expected to remain active across the regional waters in association with this system. This system is being monitored for potential tropical development, and has a medium chance of formation through 48 hours, and a high chance through 7 days. $$ PMZ111-161000- Guatemala and El Salvador to 250 nm offshore- 247 PM PDT Sun Jun 15 2025 .TONIGHT...NE winds 10 to 15 kt.
