Two hurricanes are churning with no threat to land in the Atlantic Ocean: Kirk, a Category 3 storm, and Leslie, which became a hurricane late Friday.

Hurricane Kirk continues to strengthen in the Atlantic Ocean and could bring large swells to the east coast of the United States by Sunday, according to the National Hurricane Cen

Hurricane Kirk is in the middle of the Atlantic Ocean, nowhere near land. But the storm, which was classified as a Category 4 storm as of Friday, Oct. 4, could still affect North Carolina, the East Coast and islands including Bermuda and the Bahamas, according to the National Hurricane Center.
