What the water does

National Weather Service impact statements for this gauge, in the Weather Service's own words.

5.5 ftMinor flooding of the prone low-lying coastal locations possible depending on winds and wave action.
6.0 ftAt Wrightsville Beach, Channel Avenue at Sweeney Avenue may begin to flood. Minor street flooding occurs on the sound-side of Carolina Beach, along Canal Drive from Starfish Lane northward. Water gets into yards along the sound, but the street flooding is mainly the result of salt water backing up through the storm drains. Heavy rain at the time of high tide exacerbates this problem.
8.0 ftOn Figure Eight Island, Oyster Catcher Road and Beach Road may be affected. At Wrightsville Beach, water reaches North Lumina Avenue. At Carolina Beach,Canal Drive from Starfish Lane northward may be impassable. At Carolina Beach State Park, water can reach the parking lot and building near the docks. Susceptible locations in Pender County are the south end of Topsail Beach, areas from Topsail Beach north of Jolly Roger Pier to the south end of Surf City, and the north end of Surf City near the county line.
10.0 ftLife 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.
