Shown on a topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the shores of St. Andrews Bay, Mobile Bay, and Bon Secour Bay from Fort Morgan eastward to about four miles east of Gasque, Ala. The storm tide went completely across the land between the beach and Mobile Bay throughout much of the area. Most homes on the beach side of Alabama State Highway 180 were completely destroyed, and the highway was washed out in several places. Damage to homes and other structures on the bay side was not as great. Storm-tide frequency and records of annual maximum tides at Mobile, Ala., since 1772, are presented. Offshore winds reached about 160 miles per hour. A wind-velocity of about 145 miles per hour was recorded near Dauphin Island, Ala.
