"There’s very high confidence that Florence will reach the southern coast of North Carolina on Thursday night as a very dangerous major hurricane. It now looks increasingly possible that Florence will stay near the coast (either inland or just offshore) for a day or longer, perhaps moving southwest along the coast. In this case, the coastline north of the center could experience storm surge during at least two 12-hour tidal cycles, rather than just one, and at least some surge could spread southwest with Florence. Florence’s track beyond Friday is still subject to major change as the weak steering currents evolve."

Can you imagine that thing staying just off the coast for 24 hours or more? What a battering that will be.
