Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
225 AM EDT Tue Jun 30 2026
.SYNOPSIS...
A backdoor front will push into the southeast Georgia waters this
morning and shift south of the northeast Florida waters later this
afternoon. A surge of northeasterly winds develop in the wake of the
front and continues into Wednesday. The onshore flow will keep
thunderstorm activity mainly on land through the middle of the week.
The front lifts back northward into the area as remnant inverted
trough on Thursday resulting in an increase in rain and storm
chances. As surface high pressure builds to the south, a weak
southwesterly flow will develop into the Independence Day holiday
weekend and increase chances for thunderstorms.
