Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
225 PM EDT Wed May 13 2026
.SYNOPSIS...
A weak wave of low pressure located near the Gulf Stream waters
adjacent to coastal Georgia will shift eastward through tonight as a
slow moving frontal boundary pushes south of the northeast Florida
waters. Scattered showers and isolated thunderstorms will remain
possible through around sunset this evening across our local waters.
Winds will shift to northwesterly later tonight, allowing seas to
gradually subside. A dry cold front will then approach our region
from the northwest on Thursday morning, followed by weak high
pressure building over the southeastern states on Thursday night and
Friday. This high pressure center will then shift offshore of the
southeastern seaboard this weekend, with southeasterly winds
gradually increasing and becoming breezy across our local waters
through the early portions of next week, especially during the
afternoon and evening hours.
