GMZ005-242300- Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas 1248 PM EDT Tue Sep 24 2024 .SYNOPSIS...Moderate to fresh east to southeasterly breezes will continue to slowly increase through the afternoon. This will be in response to a high pressure building along the Eastern Seaboard, and Tropical Storm Helene in the northwestern Caribbean Sea. Tropical Storm Helene is expected to continue moving slowly northwestward through Wednesday morning before turning more north and then north northeastward while accelerating Wednesday afternoon through Thursday. The closest pass from Helene to the Florida Keys coastal waters is expected to be Wednesday evening through Thursday morning when the peak southeasterly wind and highest seas is expected to occur. As the storm passes, breezes will shift to the south to southwest while gradually diminishing with seas gradually subsiding Thursday night through Friday. Winds further diminish heading through the weekend.
