The storms stacking up in the tropics come just as the season hits its historic high point when the tropical Atlantic becomes ripe for hurricanes.
The odds of a depression or storm forming in two days is 70 percent and 90 percent in five days, forecasters said.
Even if Florence stays out to sea, models show numerous other systems developing over the Atlantic, nearly on cue as the hurricane season hits its peak on September 10. It is forecast to fluctuate between category 2 and 3 strength through the upcoming weekend and into early next week.
The first major hurricane of the 2018 Atlantic season, Florence on Wednesday afternoon had maximum sustained winds of 125 miles per hour, according to the National Hurricane Center.
The storm, swirling away in the mid-Atlantic, was moving slowly northwest at about 10 miles per hour, according to the NHC. The minimum central pressure is 989 mb.
"A turn towards the west is expected tomorrow", the NHC wrote in its update.
Behind it, another wave is expected to move off the coast on Friday and could become a depression over the weekend or early next week.More news: Alex Jones heckled Marco Rubio right outside Twitter and Facebook’s Senate hearing
It's far too soon to tell how Hurricane Florence may affect the Carolinas.
There now are no hurricane watches or warnings in effect, though a possible timetable for an approach on Bermuda is most likely Tuesday, according to a report by The Weather Channel.
There's also a second area of storms just now moving off the coast of Africa that has some chance of tropical development over the next five days.
The Hurricane Center reported at 8 a.m. that a tropical depression could form over the weekend or early next week while the wave moves westward or west-northwestward over the far eastern tropical Atlantic Ocean.
The focus on Florence comes less than a day after Tropical Storm Gordon made landfall on the US Gulf Coast, leaving one child dead and ushering storms through Monday across the western South and the Midwest.
Interests in the Cabo Verde Islands are being warned to monitor the progress of this system during the next several days because there is a much better chance of early strengthening with this developing storm system.
