Hurricane Florence may become only the fourth Category 4 hurricane to make landfall along the US East Coast north of the state of Georgia, with the others being Hugo (1989), Gracie (1959), and Hazel (1954), according to the National Oceanic and Atmospheric Administration's historic database.
"As we have seen with hurricanes in most recent years, such as Lane in Hawaii earlier this summer and Harvey last year in Texas, feet of rain can fall when these tropical storms stall", Sosnowski said.
USC Athletics sends its thoughts and prayers to those preparing for the storm and hope that you will be safe and careful during this time.
The UK Foreign Office (FCO) said in its travel advisory: "Hurricane Florence is forecast to bring life-threatening weather conditions to North Carolina and SC, with potential effects in coastal Georgia and Virginia".
He said: "We here in North Carolina are bracing for a hard hit".
Florence was producing large swells expected to reach from the northern Caribbean to the southern coasts of Canada's maritime provinces.
South Carolina's governor ordered the state's entire coastline to be evacuated starting at noon on Tuesday.
A warm ocean is the fuel that powers hurricanes, and Florence will be moving over waters where temperatures are peaking near 85 degrees (30 Celsius), he wrote. Category 4 is one level below the most severe storm, and the center warned that Florence would remain an "extremely unsafe major hurricane through Thursday night".
Vice President Mike Pence added: "We are with the great people of SC and North Carolina as they brace for Hurricane Florence". Governor of North Carolina, Roy Cooper, said: "The time to prepare is nearly over, Disaster is at the doorstep and it's coming in".
By noon on Monday, Florence had top sustained winds of 130mph.
As of 2 p.m. EDT today (Sept. 12), Florence was a Category 3 hurricane with winds of 125 mph (205 km/h) at its location about 435 miles (700 kilometers) southeast of Wilmington, North Carolina, according to the National Hurricane Center in Miami.
Hurricane Helene, heading north in the Atlantic, isn't expected to cause the USA any issues, the NHC said.
In such winds, downed trees and power outages are common, and well-built homes can suffer heavy damage, the NHC says.
Long-duration hurricane-force winds of 74 miles per hour or higher could cause tremendous damage and widespread power outages. The governors of both states declared states of emergency.
"The centre of Florence will move over the southwestern Atlantic Ocean between Bermuda and the Bahamas Tuesday and Wednesday, and approach the southeastern coast of the USA on Thursday", the NHC said. NASA cameras also captured the storm earlier in September as it churned across the North Atlantic. The space agency described the footage as "a stark and sobering" view of the storm, as it moved with wind speeds of 130 miles per hour. McMaster estimated about 1 million residents would be fleeing the coast before Florence's arrival.
"Get prepared on the East Coast, this is a no-kidding nightmare coming for you", Gerst said.
Northam's decision comes after costal communities in North Carolina ordered mandatory evacuations and SC officials ordered an evacuation of their entire coast line.
The Category 4 storm's approach led to a series of schedule adjustments Tuesday for teams in the Carolinas and Virginia.
