One of the highest tides of the year, called a king tide, caused flooding on the Georgia coast this week. Volunteers are collecting data about it, to be better prepared next time.
The only higher tides ever recorded at the tidal gauge at Fort Pulaski near Savannah were during hurricanes. The bridge connecting Tybee Island to the mainland was submerged, and homes and streets on the island were flooded.
Scientists knew it was going to be a really high tide, but wind pushed it even higher than predicted, said Mark Risse, director of University of Georgia's Marine Extension.
