Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
227 PM EDT Mon Apr 27 2026
.SYNOPSIS...
Strong high pressure centered over the Mid-Atlantic states will
continue to push a frontal boundary southward down the Florida
peninsula. Strong northeasterly winds will persist across our local
waters through early this evening, creating Small Craft Advisory
conditions throughout the northeast Florida and offshore waters
adjacent to southeast Georgia through late this evening. High
pressure will then weaken as it slides southeastward on Tuesday,
becoming positioned off the southeastern seaboard, allowing for
onshore winds and seas to gradually subside through Tuesday night. A
cold front will then enter the southeastern states on Wednesday,
possibly bringing a few showers and thunderstorms to the Georgia
waters during the afternoon and evening hours. This front will then
slowly move across the rest of our local waters on Thursday and
Thursday evening, accompanied by showers and thunderstorms. This
front will briefly shift south of our region on Friday before a wave
of low pressure develops over the Gulf this weekend, likely
spreading additional showers and thunderstorms across our local
waters during the upcoming weekend.
