Tropical Storm Kirk is unusual because it formed farther south than normal in the Atlantic Ocean off Africa.
Kirk is located 465 miles south-southwest of the southernmost Cabo Verde Islands.
Winds are sustained at 40 miles per hour and is moving west at 14 miles per hour.
Forecasters say Tropical Storm Kirk is continuing to move west across the eastern Atlantic but does not now pose any threat to land. Further weakened by dry air and strong wind shear, Isaac dissipated in the Caribbean on September 15. Kirk will then weaken during the middle to latter portion of the week as it nears the Lesser Antilles.
"Low- to mid-level ridging over the eastern Atlantic is expected to cause Kirk to move even faster toward the west during the next couple of days, reaching speeds of at least 22 kt in 24-36 hours", forecasters said. Once the afternoon settles in, expect to see those storms forming to the east and moving to the west.
The tropical depression is forecast to become a remnant low before the weekend end as it is moving through an area of high wind shear. Conditions are favorable that this one could gain subtropical or tropical characteristics, forecasters say, and "a subtropical or tropical cyclone is likely to form by early next week while the low meanders over the central Atlantic Ocean".
There is a another system southeast of Bermuda.
The tropics are active once again with two disturbances, a depression, and tropical storm.
Tropical Depression Eleven is about 500 miles east of the Windward Islands.
"It's got all the ingredients it needs to become a strong storm, a major hurricane, so we want you all to take this very seriously", WRAL meteorologist Kat Campbell said.
At 5 a.m., the center of the poorly organized depression was located near 14.5 degrees north or about 320 miles east north-east of Barbados.
