12 Flooding of historic proportions in Shell Point and Live Oak Island. Water will be up to 9 ft deep in some areas. Further inland, homes south of US-98 near Wakulla Beach Road flood. Portions of US-98 east of Spring Creek Highway flood at this level.
9 Catastrophic flooding at Shell Point and Live Oak Island. Much of the area is flooded up to 6 feet deep. Any structures not elevated will suffer significant damage and possible destruction due to wave action.
6 Significant flooding at Shell Point and Live Oak Island. Access to the area becomes impossible. Water covers the area up to 3 feet deep in places. Structures not elevated suffer significant damage.
5 Much of Shell Point and Live Oak Island are flooded by water 1 to 2 feet deep. Structures not elevated flood at this level.
