The combination of favorable winds and increased astronomical factors produced major coastal flooding along portions of the southeast South Carolina coast with the evening high tide cycle. Tidal departures were driven strongly positive thanks to multiple days of strong northeasterly winds and the occurrence of the new moon cycle on 5/19/23. Flooding was reported across coastal portions of Charleston and Colleton counties.
