Synopsis for Flagler Beach to Jupiter Inlet out to 60 nm 237 AM 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 and night, some of which have the potential to become strong. Onshore flow strengthens into next week, leading to somewhat less favorable boating conditions.

GULF STREAM HAZARDS
None.
