Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1122 AM EST Wed Dec 18 2024
.SYNOPSIS...
Elevated seas will remain in place today, especially offshore.
Meanwhile, a persistent coastal trough will develop scattered
showers and isolated thunderstorms later this afternoon, mainly
across the northeast Florida waters. This trough will lift
northward this evening ahead of an approaching cold front. Dense
sea fog will likely redevelop before midnight across our local
waters, and may persist through the early morning hours on
Thursday before the front crosses our local waters. Northwesterly
winds will develop on Thursday in the wake of this front, with
winds then shifting to northerly by late Friday as a reinforcing
dry cold front pushes southward through our area. Strong high
pressure building over the Great Lakes region in the wake of this
reinforcing front will result in strengthening north-
northeasterly winds and building seas from Friday night through
the weekend, with Small Craft Advisory conditions expected
offshore and possibly near shore.
