Synopsis for Flagler Beach to Jupiter Inlet out to 60 nm
917 AM EDT Sat Oct 17 2026
.SYNOPSIS...A cold front pushing through the local Atlantic
waters, deep high pressure over the eastern United States, and a
low developing off the eastern seaboard will lead to rapidly
developing hazardous to dangerous boating conditions today. The
front is forecast to stall south of the area while the low and
high pressure areas become nearly stationary, causing unsafe
conditions to persist into early next week. High coverage of
showers and embedded storms continue along and ahead of the front,
and then gusty scattered showers will push toward the coast and
onshore behind the front through early next week.
.GULF STREAM HAZARDS...Conditions rapidly deteriorate today, with
northerly winds increasing to 20 to 30 knots through this afternoon
into tonight, with occasional to frequent gusts to gale force.
Seas build to 6 to 9 feet this afternoon and up to 10 to 13 feet
tonight.
