Synopsis for Flagler Beach to Jupiter Inlet out to 60 nm
1056 PM EDT Sat Jul 19 2025

.SYNOPSIS...High pressure ridge over the subtropical Atlantic will
remain across the Florida peninsula through Sunday, with
generally favorable albeit hot boating conditions and below normal
rain chances forecast. The ridge axis then gradually drops south
early next week as a frontal boundary stalls just north of the
waters, leading to a return of high rain and storm chances. There
is potential for a low pressure system to develop along this
boundary, leading to deteriorating boating conditions.

.GULF STREAM HAZARDS...None.

The approximate location of the west wall of the Gulf Stream based on
the Real Time Ocean Forecast System as of Saturday, July 19th, 2025.

48 nautical miles east of Ponce Inlet.
33 nautical miles east of Port Canaveral.
28 nautical miles east of Sebastian Inlet.
