Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1151 AM EDT Mon Aug 31 2026
.SYNOPSIS...
High pressure will remain centered over the southern Appalachians
through midweek, with coastal troughing remaining situated over our
near shore Atlantic waters. This weather pattern will create
breezy onshore winds this afternoon, but Small Craft Advisory
conditions are not expected this week. Showers and thunderstorms
impacting the Georgia waters late this morning will diminish early
this afternoon as activity develops inland. Additional rounds of
showers and embedded thunderstorms will be possible across our
local waters tonight and Tuesday, mainly from the evening through
the overnight and morning hours, with decreasing coverage during
the afternoon hours as activity shifts inland. Showers and
thunderstorms will then increase in coverage throughout our local
waters on Thursday and Friday as another trough progresses
westward from the Atlantic waters across our region. Onshore winds
will prevail through Saturday, followed by winds shifting to
westerly by Saturday night and Sunday as a frontal boundary enters
the southeastern states. Several rounds of showers and
thunderstorms are possible during the upcoming weekend ahead of
this frontal boundary.
