The center of the hurricane was to move between Bermuda and Bahamas on Tuesday and Wednesday and approach the southeastern coast of the United States on Thursday as a Category 3 or higher storm, according to the Hurricane Center.
"Florence should quickly turn into a massive hurricane Monday night and should remain an extremely dangerous hurricane until Thursday," said the National Hurricane Center.
The big waves generated by Florence already affect Bermuda and parts of the East Coast and will continue this week, said the hurricane center.
"These waves are likely to cause deadly surf and tear currents," said the National Hurricane Center.
East Coast Trail
CNN chief meteorologist Dave Hennen said Sunday that computer models agreed that Florence was about to land in the Carolinas.
It would be the first category 3 or higher storm to hit the east coast since Jeanne hit Florida in 2004.
According to Hennen, most computer models predict that Florence will slow down as it moves inland, which could worsen heavy rains and potential floods.
Virginia, North Carolina and South Carolina are already on alert. Their governors declared the state of emergency Friday and Saturday.
"We are preparing for the worst and hope everything will be fine," said South Carolina Governor Henry McMaster, adding that his statement would allow state agencies to quickly deploy resources on the coast.
McMaster said Sunday that he had asked President Trump a federal disaster declaration. This would make the state and local agencies eligible for reimbursement of certain costs by FEMA.
Cooper also urged people to learn the escape routes to take and put fuel in their vehicles in case they would be ordered to leave.
"Today's action can avoid losses due to Florence," he said.
Ships at sea
The US Navy said Saturday that it may be necessary to send ships to the Norfolk area of Virginia due to the upcoming storm. The Navy put them on the Condition Bravo exit, which means that the destruction time is 48 hours.
In a press release, the Navy said the ships could better manage the destructive weather at sea and that "the current ships made them ready and available to meet all national tasks, including the storm has passed. "
High season
The preparations for Hurricane Florence arrive as the Atlantic Hurricane strikes its apogee. Two other storms also occur in the Atlantic.
Hurricane Helene and Hurricane Isaac should not touch the American continent.
Monday is the climatological peak date of the hurricane season, at the height of the eight-week period during which the most powerful storms are forming, said CNN meteorologist Pedram Javaheri.
The Atlantic hurricane season officially began on June 1, but the cooler waters and wind shear – winds blowing at different speeds and directions – at the start of the season are less than ideal for the tropical systems are gaining and maintaining their strength.
Storms increase in frequency and intensity between mid-August and September, as temperatures in the Atlantic reach their highest level, said Javaheri.
"Between mid-August and mid-October, this period represents 87% of category 1 and 2 hurricanes and 96% of" big "hurricane days (categories 3, 4 and 5)," he said. . "At the end of October, the wind shear increases again and the cooler air of the fall stops further south, allowing the waters to begin their inevitable cooling process.
CNN meteorologist Gene Norman compared the conditions with boiling water on a stove, the water taking a while to react to an increase and then a decrease in the temperature of the element below.
"Even though the season starts in June, the Earth is just starting to warm up in the summer sun, and in mid-August temperatures are approaching their peak, like the pot on the fire that's starting to boil," he said. declared. "However, just as it takes a while to heat the ocean, it takes a while for the stored latent heat to dissipate, like that pot on the stove. That's why there may be some strong storms in October. "
