Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
139 PM EDT Fri Jul 10 2026
.SYNOPSIS...
Atlantic high pressure will continue to extend its axis westward
across the Florida peninsula through Saturday morning, with this
weather pattern maintaining a prevailing southwesterly wind flow
during the overnight and morning hours, with southeast and southerly
winds then surging to Caution levels during the late afternoon and
evening hours as the Atlantic sea breeze shifts inland through
Saturday. Only isolated thunderstorms will be possible across the
near shore waters this afternoon, mainly from around St. Augustine
southward. Troughing will then develop over the southeastern states
by late Saturday and Sunday, with prevailing westerly winds forecast
and increasing chances for afternoon and evening thunderstorms,
especially by Sunday and Monday. A frontal boundary will then sink
into the southeastern states early next week, with this feature
likely stalling over the southeast Georgia waters by Tuesday before
weakening towards midweek. Numerous showers and thunderstorms are
forecast on Tuesday across our local waters, with coverage then
expected to gradually decrease by Wednesday and especially Thursday.
