Hurricane Matthew has been downgraded to a Category 1 hurricane.
In an advisory the US National Hurricane Centre said Matthew had maximum sustaining winds of 85mph as it headed towards South Carolina.
Matthew - which was a category 5 storm when it hit Haiti last week killing nearly 900 people - made landfall in the States on Friday.
As Hurricane Matthew approaches Florida, its 140-mile-an-hour winds have already left behind a trail of destruction in Haiti.
Residents told to fully prepare for the arrival of the hurricane with warnings its impact could be "devastating".
