Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1005 AM 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
through Monday, keeping a prevailing southerly wind flow across
our area. Afternoon sea breezes will increase wind speeds to near
Caution levels over the near shore waters late in the afternoon.
Showers and thunderstorms will impact our local waters during the
late afternoon and 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.
