routinely monitor subsequent forecast issuances and updates for

Synopsis for the coastal waters from Bonita Beach to Suwannee River-
525 AM EDT Thu Sep 26 2024

.SYNOPSIS...

Tropical Storm and Hurricane Warnings are in effect for all waters
as Hurricane Helene moves northward. The hurricane will continue to
move northward today, with very dangerous marine conditions
continuing as it strengthens into a major hurricane. Helene will
make landfall around the Big Bend region later today or tonight with
elevated winds continuing into Friday before decreasing for the
weekend. Waves will continue to build for the rest of the day and
remain elevated through Friday before beginning to decrease.
However, a persistent southwesterly flow suggests that the sea
state will take longer than normal to settle.
