HOLT, Fla., Sept. 10, 2018—Tropical Storms Helene and Isaac have joined Florence as hurricanes in the Atlantic Ocean.
Hurricane Florence continues its track toward the Carolinas.
At its current speed, a projected landfall, possibly in North Carolina, is expected late Thursday or early Friday as a category 4 hurricane.
Parts of areas as far as New Jersey, Pennsylvania, Ohio, Kentucky and Tennessee can expect to feel tropical-storm-force winds as Florence reaches the east coast of the United States.
Helene, the last of the three systems to reach hurricane status, was declared a hurricane by the National Hurricane Center at its 5 a.m. update today.
Helene is moving toward the west-northwest near 17 mph and should continue on this track for another couple of days before turning northwest Wednesday.
Maximum sustained winds are near 85 mph and area expected to strengthen today, possibly to a category 2 hurricane, before beginning to weaken Wednesday.
Hurricane Isaac is moving toward the west near 13 mph and is forecast to continue this direction with an increase in forward speed through the end of the week.
Isaac is forecast to move across the Lesser Antilles and into the eastern Caribbean Sea Thursday.
According to the NHC, Isaac is a small hurricane with hurricane-force winds only extending out to 10 miles from the center.
Maximum sustained winds remain near 75 mph with higher gusts.
Additional strengthening is expected over the next day or two, but weakening is forecast to begin by the middle of the week as Isaac approaches the Lesser Antilles.
Two other areas are being watched by the NHC as well.
Disorganized showers and thunderstorms have formed over the northwestern Caribbean Sea and western Cuba.
This disturbance is forecast to move slowly northwest across the northwestern Caribbean Sea and the Yucatan Peninsula during the next couple of days with only slow development expected.
However, upper-level winds are forecast to become more favorable and a tropical depression could form late this week when the system moves across the western Gulf of Mexico.
Formation chance through the next five days is at 40 percent.
Finally, a non-tropical area of low pressure is forecast to form in the northeastern Atlantic Ocean several hundred miles west-southwest of the Azores in about two days.
Some slow tropical or subtropical development is possible by the end of the week while the low moves southwest.
The NHC gives this area a 40 percent chance to develop further during the next five days.
