Synopsis for Flagler Beach to Jupiter Inlet out to 60 nm
301 PM EDT Thu Sep 10 2026

.SYNOPSIS...Generally favorable boating conditions prevail through
the weekend, as the Atlantic ridge axis strengthens over the local
waters. Light southerly flow becomes southeasterly and increases
to around 10 knots in the afternoons as the sea breeze develops.
Scattered to occasionally numerous showers and lightning storms
will remain a hazard each day/night (some of which have the
potential to become strong). Onshore flow strengthens into next
week which will lead to somewhat less favorable boating
conditions.

.GULF STREAM HAZARDS...None.

The approximate location of the west wall of the Gulf Stream based on

41 nautical miles east of Ponce Inlet.
