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

.SYNOPSIS...

The Atlantic high pressure southeast of Bermuda will continue to
extend its axis westward across the Florida peninsula through
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.
