By Friday evening, Potential Tropical Cyclone Six is expected to continue strengthening into a Tropical Storm, which at this point would then become the sixth named storm of the 2018 Atlantic hurricane season and be given the name Florence. But shear is forecast to decrease in the weeks ahead, leaving open the possibility for more powerful storms.
Forecasters expect the system will remain out at sea and will not threaten Florida.
Hurricane forecasters are keeping an eye on a wave in the Caribbean headed for the Gulf of Mexico while a faraway system nearing the Cape Verde Islands is expected to become a tropical depression later Friday.
Ahead of the approaching storm, the government of the Cabo Verde Islands has issued a Tropical Storm Warning for the southern islands of Santiago, Fogo and Brava.
The last time the islands had to deal with a tropical storm or hurricane was when Hurricane Fred plowed across the islands exactly three years ago. On average, the sixth named storm forms on September 6. Florence may even be able to strengthen into a hurricane over the next few days.
The weather system, which has maximum sustained winds of 35 miles per hour, is moving west-northwest at 13 miles per hour.
Elsewhere, we are watching a tropical wave near Hispaniola that is producing heavy rainfall across northern parts of the Caribbean.
A third tropical wave is forecast, by at least one model, to emerge from the African coast around Sept 7 or 8.
Most of the reliable computer models suggest the storm will intensify as it moves WNW over the next couple of days.
Florence will begin to slide to the north fairly quickly thanks to a weak space in high pressure to the north of the storm.
