The hurricane will weaken as it moves over cooler water, and is expected to be downgraded from hurricane to tropical storm status before making the transition to post-tropical storm on Sunday.
While Hurricane Florence continues barreling toward the Carolina coast, the Caribbean got some good news Wednesday: Isaac appears to be weakening.
Alachua County Emergency Management Director John Shaw said he and others at the county Emergency Operations Center are monitoring Florence's track, along with other tropical systems, like Tropical Storm Isaac.
- Isaac is now a strong tropical storm over the Central Tropical Atlantic.
As Florence nears the east coast, meteorologists are focused on two key factors: ocean temperatures and wind sheer (the difference in speeds at the upper and lower parts of the storm).

He accused Democrats of inflating the official death toll to "make me look as bad as possible". Mr Trump said people who died for any reason - "like old age" - had been added to the total.
"We do not anticipate experiencing any tropical storm or hurricane force winds, but we could experience rain and will be placed under a flash flood watch", said Governor Kenneth Mapp in a release issued late Thursday.
The National Hurricane Center is predicting the storm will produce "catastrophic flash flooding and significant river flooding". When Isaac reaches the west-central Caribbean Sea in a couple of days, the shear may relax somewhat and the global models suggest that there will be an increase in mid-level moisture. Landfall is expected early Friday.
Still closer to Africa than North America, Hurricane Helene is predicted to head northeast in the Atlantic, then veer toward Europe, the center said. Earlier forecasts showed that the storm was slated to directly hit around North and SC.
At 2 a.m., the storm was centered 625 miles (1,005 km) southeast of Cape Fear, North Carolina, moving at 17 mph (28 kph).
The Met Office also say there is a small chance injuries could occur from large waves and beach material being thrown onto sea fronts.
