Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
802 AM EDT Wed Jul 15 2026
.SYNOPSIS...
A frontal boundary stalled over the Georgia waters will lift slowly
northward as a warm front this afternoon and tonight as it weakens.
Meanwhile, weak high pressure centered over south Florida will shift
slowly westward across the Gulf through Friday, creating a
prevailing northwesterly flow across our local waters, with a late
afternoon sea breeze developing today and then earlier in the
afternoon on Thursday that will shift winds to onshore over the near
shore waters. Scattered late afternoon and evening showers and
thunderstorms will be possible today and Thursday, mainly over
the near shore waters, followed by coverage decreasing to isolated
on Friday afternoon and evening. Troughing developing over the
southeastern states this weekend and early next week could bring
widely scattered, mainly late afternoon and evening thunderstorms
back to our local waters as southwesterly winds prevail.
