 CHANGES WITH THIS ADVISORY: The Government of Mexico has issued a Tropical Storm Watch for the

 east coast of the Yucatan Peninsula from Tulum to Cabo Catoche. Subtropical Storm Alberto – the first named storm of the 2018 hurricane season – roiled parts of coastal Mexico and Cuba with rip currents and dangerous surf before plodding northward Saturday. On the foreast track,

 Alberto is expected to pass near the eastern coast of the Yucatan

 peninsula tonight, be near the western tip of Cuba Saturday morning,

 emerge over the southeastern Gulf of Mexico by Saturday night, and

 approach the north-central Gulf Coast on Monday. "Environmental conditions are forecast to become more conducive for development through early next week, and a subtropical or tropical depression is likely to form by late Saturday over the southeastern Gulf of Mexico. "In addition, the threat of rip currents will steadily increase along the Gulf coast from Florida westward to Louisiana over Memorial Day weekend.”
Subtropical Storm Alberto becomes the first named storm of the 2018 Atlantic hurricane season. It formed at the western Caribbean Sea and is expected to move north of the Gulf of Mexico later in the weekend.
