Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
216 PM EDT Mon Apr 7 2025

.SYNOPSIS...

Gusty south to southwest winds will continue this afternoon as a
cold front approaches our area this afternoon, with Small Craft
Advisory conditions expected. Showers and thunderstorms will
overspread our local waters during the evening hours ahead of this
frontal passage, with isolated strong to severe thunderstorms
possible. Winds will shift to northwest in the wake of this
frontal passage during the overnight hours tonight and then north
on Tuesday as high pressure builds into the Ohio Valley. This high
pressure center will wedge down the southeastern seaboard from
Tuesday night through Wednesday night, creating strengthening
northeast winds and building seas. Another cold front will move
quickly southeastward towards our region on Friday afternoon and
evening, accompanied by showers and possibly a few thunderstorms.
High pressure will build Northwest of the region on Saturday.
