Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
227 PM 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.
