The National Hurricane Center said the storm was expected to continuing growing in strength through the day. The advice has been that anyone living along the coast of Georgia, South Carolina, North Carolina, and Virginia should be monitoring the forecast.
Florence is located approximately 750 miles southeast of Bermuda.
The storm is 685 miles southeast of Bermuda, moving westward at 7 mph with maximum-sustained winds of 90 mph - and it's strengthening as it heads toward the East Coast.
Although it is quite a distance away, swells generated by Florence will begin to impact the southeastern United States, including Florida, today and through much of next week.
"Tropical-storm-force winds extend outward up to 60 miles from the centre". Northern coastal counties will likely all see more than nine inches, experts predict.
Swells generated by Florence could cause unsafe rip currents and coastal flooding Saturday in areas including coastal DE and New Jersey, the National Weather Service said.

Helene - now just southeast of the Cabo Verde islands off the African coast - had winds of 85 miles per hour, and was expected to turn northwest and then north into the open Atlantic by midweek, the NHC said.
Maximum sustained winds have increased to near 40 miles per hour (65 kilometres per hour) with higher gusts. The rapidly intensifying storm could strike a direct and risky blow anywhere from the Carolinas to the Mid-Atlantic region later this week, possibly as a fearsome category 4.
The hurricane center projects that Helene will strengthen Monday but "weakening is forecast to commence Wednesday morning".
From there, Helene is expected to curve to the north and remain out to sea. Based on the current forecast, Isaac will be near the Lesser Antilles in four to five days, the NHC said.
Interests in the Lesser Antilles should monitor the progress of Isaac for updates.
As at least three storms churn their way towards the Caribbean and North America, Evan Thompson, director of the Meteorological Service Division, is warning that, statistically, the peak of the hurricane is now here. It was moving west at 10 km/h. Florence is expected to remain an extremely risky major hurricane through Thursday.
