Synopsis for Flagler Beach to Jupiter Inlet out to 60 nm 246 AM EDT Sat Jun 20 2026

SYNOPSIS
Generally favor boating conditions outside of offshore moving lightning storms. The ridge axis of the Atlantic high is forecast to be shunted over South Florida to the Straits of Florida, where it will remain through the period as low pressure systems pass to the north. Offshore (SW-SSW) winds shifting onshore (SSE-SE) in the afternoon to early overnight behind the sea breeze will continue through the weekend and most of next week. Primary hazard will be offshore moving showers and lightning storms in the afternoons and evenings, especially today and Sunday. Rain and storm chances over the Atlantic waters decrease going into the work week.

GULF STREAM HAZARDS
None.
