JACKSONVILLE, Fla. — Between Oct. 9-11, coastal flooding occurred on the First Coast from southeast Georgia to Flagler Beach, due to the combination of king tides and a nor’easter. Most regions experienced water levels 1-3 feet above normal, though at certain places like the Matanzas Inlet, gauge readings showed over 4 feet above normal high ground during high tide.
First Coast News Weather Watchers shared the conditions in their neighborhood showing where flooding was and how it impacted their community.
