Synopsis for Flagler Beach to Jupiter Inlet out to 60 nm 830 PM EDT Sun Apr 12 2026

SYNOPSIS
Poor to hazardous marine conditions persist tonight and into early week. A moderate to fresh easterly breeze continues as high pressure builds over the eastern seaboard and western Atlantic, keeping seas elevated. Winds finally ease early this week as high pressure shifts offshore into the subtropical Atlantic, allowing seas to subside. Flow remains onshore as the ridge axis stays anchored over North to Central Florida.

GULF STREAM HAZARDS
East winds 15 to 20 knots and seas 5 to 7 feet.
