Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1230 AM EST Thu Mar 5 2026
.SYNOPSIS...
Dense sea fog at times will lead to difficult navigation conditions
across the waters through the rest of the week, especially during
overnight periods. There will be periods over the next few days
where fog lifts to stratus, but prevailing visibilities will
generally be low, especially within about 20 to 30nm from the coast.
Sea fog is likely to continue through the weekend as warm, moist air
is pushed across the water by southeasterly flow. Otherwise, surface
high pressure will remain fairly stationary, near Bermuda,
throughout the next week.
