Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
1043 AM EDT Sat Aug 8 2026
.SYNOPSIS...
Troughing over our local waters this afternoon will lift northward
towards the Carolina coast as Atlantic high pressure centered near
Bermuda builds westward towards the Florida peninsula. Widespread
showers and thunderstorms are expected through late this afternoon,
with strong to isolated severe storms containing gusty winds,
frequent lightning strikes, and waterspouts possible. Elevated
seas this afternoon will then gradually diminish tonight and
Sunday. Atlantic high pressure will briefly build northward across
the northeast Florida waters on Sunday and Monday before this
feature weakens while sinking southward by midweek as troughing
develops over the southeastern states. Coverage of showers and
thunderstorms will gradually decrease through Monday across our
local waters, with unseasonably dry conditions then forecast for
much of next week as southwesterly winds prevail.
