As of Sunday night, hurricane-force winds extended outward up to 25 miles from Florence's center, while tropical storm winds extended up to 125 miles.
German astronaut Alexander Gerst posted photos of the massive hurricane, which is now a category four storm on the five-step Saffir-Simpson scale, online from space.
Tropical storm force winds are in the 39 miles per hour to 73 miles per hour range, says NOAA.
If the latest forecast holds, Florence will strike farther north on the East Coast than any other Category 4 hurricane in history.
During a press conference on Saturday, the governor issued an executive order declaring a State of Emergency for the state of sc. It's possible that a storm surge between one and three feet may impact coastal Chesapeake Bay areas.
The cone "is trying to take in some of the uncertainty and show all areas of risk", Joel Cline, a meteorologist and tropical storm coordinator with the National Oceanic and Atmospheric Administration (NOAA), told Fox News on Tuesday.
A state of emergency has been declared in three USA states, as the east coast braces for the arrival of category five storm Florence.
Decreasing modestly in strength but expanding in size, Category 3 Hurricane Florence is less than 48 hours away from making landfall on the Southeast American coast with catastrophic impacts, from damaging winds to flash flooding to widespread power outages.
Experts say this could be the strongest storm to hit the Carolina coast in more than 60 years. Rather than pushing up toward western Virginia, the storm's center is now predicted to move across the middle of SC. He told The Chronicle Sunday that once Florence hits land, destructive winds and vast rainfall flooding may take hold of the area. This will lead to widespread and unsafe flooding, inundation of roads and damaged infrastructure.
At the moment, the hurricane is set to hit North Carolina, South Carolina, and parts of Georgia and Virginia.
Hugo in 1989 was the last major hurricane to hit the SC coast.
