129 AM EDT Tue Oct 7 2025

.SYNOPSIS...

Small craft advisory combined seas will continue within the local
waters through mid-week as surface high pressure builds offshore of
the mid-Atlantic coast. A front approaches from the north late
Wednesday, then the front shifts south of the local waters Thursday
as high pressure builds northeast of the region and strengthens
southward. A return of strong northeast winds is expected Thursday
and winds are expected to further strengthen Friday into Saturday as
a surface low develops east of the southeast Atlantic coast. Strong
winds and building seas will once again bring Small Craft conditions
across all local waters with the potential for gusts to gale force.
A gale watch may be needed mid-week.
