Tropical Storm Igor, in the eastern Atlantic off the Cape Verde Islands, will probably strengthen steadily as it moves into warm waters and become a hurricane before next week, according to the National Hurricane Center.
Igor, with sustained winds of 40 miles (65 kilometers) per hour, was about 65 miles west-southwest of the Cape Verde islands and was moving northwest at 10 mph, the U.S. National Hurricane Center said in a website advisory at about 1:30 p.m. East Coast time.
Tropical storm watches for Cape Verde’s southern islands will probably be lifted later today.
Igor is the ninth named storm of the June-through-November Atlantic hurricane season. The system is forecast to become a hurricane, with sustained winds of at least 74 miles per hour, in about three days and take a turn to the north when it hits a trough over the central Atlantic, the agency said.
The center also said a patch of showers and thunderstorms near the Caribbean’s Windward Islands has a 40 percent chance of strengthening into a depression or tropical storm over the next two days. The remains of Tropical Storm Gaston are no longer being tracked.
