Figure 26. Plot shows surface-water level at well clusters in Florida Bay and the Atlantic Ocean during passage of Hurricane Georges, September 24-26, 1998 (from Reich et al., 2002). Bay-water level dropped ~1 m and the ocean level rose ~0.5 m. The storm surge occurred during a low tide, minimizing flooding of the low-lying keys (highest natural elevation in the keys is ~5.5 m; Lidz and Shinn, 1991). Water-level data are referenced to the North American Vertical Datum of 1988 (NAVD88).
