Synopsis for the coastal waters from Bonita Beach to Suwannee River-
258 PM EDT Tue Sep 24 2024

.SYNOPSIS...

Winds and seas will be quite for the rest of today. However
Tropical Storm Helene is expected to enter the southern Gulf of
Mexico by Wednesday as it starts to strengthen. We will see winds
and seas increase throughout the day on Wednesday. Helene will
start to push into our water on Thursday as a major hurricane. We
will see dangerous to life threatening boating conditions with
wave getting above 25 feet in our offshore waters with hurricane
force winds. By Friday Helene will be pushing into Georgia but
winds will stay gusty out of the southwest with gusts up to 30
knots. By the weekend winds look to subside to around 10 knots out
of the southwest.
