The National Hurricane Center's (NHC) latest update reads: "On the forecast track, the centre of Florence will move over the southwestern Atlantic Ocean between Bermuda and the Bahamas through Wednesday, and approach the coast of North Carolina or SC on Thursday".
The South Carolina governor ordered the state's entire coastline to be evacuated starting at noon Tuesday and predicted that 1 million people would flee. "It's going to destroy homes", said Jeff Byard, an official at the Federal Emergency Management Agency.
"Isaac is a small hurricane and uncertainty in the forecast is greater than normal", the National Hurricane Center reported Monday at 11 a.m. Although Olivia is expected to move over the islands as a tropical storm, it could still bring worse impacts than recent Hurricane Lane to some areas, the center said.
As of Monday night, there are three hurricanes in the Atlantic Ocean.
The NHC said the vast storm had maximum sustained winds of 85 miles per hour, reaching up to 125 miles from its centre, as it tracked west-northwestward across the western Atlantic.

Hurricanes Florence, Isaac and Helene are all gaining strength as they churn through warm waters in the Atlantic Ocean towards eastern U.S. states and Caribbean islands.
"Life-threatening freshwater flooding is likely from a prolonged and exceptionally heavy rainfall event, which may extend inland over the Carolinas and Mid Atlantic for hundreds of miles as Florence is expected to slow down as it approaches the coast and moves inland".
Three People Missing After Colorado River Boat Collision
Rescuers abandoned the search until Sunday morning because of the danger to divers working in the fast-flowing water after dark. The Mohave County Sheriff's Office said it will continue to patrol the Colorado River until all passengers are accounted for.
Trump has declared states of emergency for North and SC and Virginia, and canceled campaign events Thursday and Friday in anticipation of the storm.
The storm's coastal surge could leave the eastern tip of North Carolina under more than 9 feet of water in spots, projections showed.
SC and North Carolina have ordered evacuations for people living in vulnerable areas along the coast.
We'll just have to wait and see where all of them go.
In the village of Buxton, Liz Browning Fox plans to ride the storm out in her house on top of a ridge.
Florence is a major Category 4 hurricane with winds of 140 miles per hour.
But, she added, she's not sure whether going inland would be much safer: "I don't know where to go from here". Florence is heading towards Virginia and the Carolinas, where a state of emergency has been declared, and Helene appears to be heading north, well away from land. "There is no way to be completely safe".
