Life threatening, and widespread coastal flooding is expected with significant damage to coastal structures and roadways. Water may enter beachfront structures not elevated on pilings. Nearly all waterfront and coastal access roads will be closed, possibly for an extended period of time. Significant inundation of coastal, bayside, sound-side tributaries and tidal creeks is likely.

High astronomical tides along with heavy rainfall can create flooding along Ocean Blvd. in Holden Beach. In Sunset Beach, one mile inland on Clubhouse Rd. near Calabash Creek Bridge can flood with high astronomical tides and heavy rain.

Minor coastal flooding affects the southern shore of Bald Head Island along Bald Head Road, and the east end of Ocean Isle Beach. Minor flooding can also occur on roadways near tidal marshes and creeks.
