Astronomical effects including a full moon and upcoming lunar perigee combined to produce an elevated morning high tide. The level of the high tide was driven even higher by the presence of strong northeasterly winds along the coast due to strong surface high pressure centered between the Mid Atlantic states and New England. The high tide resulted in coastal flooding along the southeast Georgia coast including Savannah and Tybee Island.
