The "probable" forecast path for Florence, a Category 4 hurricane, as of 5 a.m. Wednesday showed the storm shifting further toward the southern North Carolina coast and the northern half of the SC coast, with the forecast cone stretching into Georgia, western North Carolina and Tennessee, according to the National Hurricane Center.

"This will likely be the storm of a lifetime for portions of the Carolina coast, and that's saying a lot given the impacts we've seen from Hurricanes Diana, Hugo, Fran, Bonnie, Floyd and Matthew", it said.

As of 8 p.m. Wednesday, the storm was centered 335 miles southeast of Wilmington, North Carolina, moving northwest at 16 mph.

"It's possible it could be even higher than that depending on how quickly the storm moves to the coast, but we're kind of expecting it to slow down as it moves to the coast and would probably cut down the storm surge", AccuWeather hurricane expert Dan Kottlowski says. Catastrophic floods could follow if the storm stalls inland, it said.

In a video message on Twitter, President Trump added: "Hurricane Florence is fast approaching, it's going to be here in the next 48 hours and they say it is about as big as they have seen coming to this country and certainly to the east coast as they have ever said".

When it reaches the coastline, it could sit around for days, unloading life-threatening storm surge, risky winds and flooding rain.

Officials in several states have declared states of emergency, including in the Carolinas, Georgia, Virginia and Maryland, where coastal areas are still recovering from summer storms.

"A storm with the track of Florence is unprecedented".

Their entire neighborhood evacuated in Wilmington, North Carolina, David and Janelle Garrigus planned to ride out Florence at their daughter's one-bedroom apartment in Charlotte. "That means the more trees that could fall, the more power outages", National Hurricane Center Director Ken Graham said.

"We're going to stay tight and check on everybody", he said.
