Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
220 PM EDT Sun Jun 15 2025

.SYNOPSIS...

Atlantic high pressure centered to the southeast of Bermuda will
continue to extend its axis westward across the Florida peninsula
tonight and Monday, keeping a prevailing south southwesterly wind
flow across our area. Showers and thunderstorms will impact our
local waters during the afternoon and early evening hours, with a
few strong storms possible, bringing briefly gusty winds, frequent
lightning strikes, and torrential downpours. Atlantic high
pressure will then lift its axis northward towards our local
waters on Tuesday and Wednesday, likely resulting in less
afternoon and evening thunderstorm coverage as southeasterly winds
prevail. Atlantic high pressure will then shift its axis southward
across the Florida peninsula late this week as a cold front enters
the southeastern states, resulting in prevailing southwesterly
winds and increasing chances for late afternoon and evening
thunderstorms by Friday.
