Gordon, which passed over the Azores as a hurricane, is losing strength and should dissipate within two days, the U.S. National Hurricane Center said.
Gordon’s winds dropped to 45 miles (75 kilometers) per hour as of 5 p.m. East Coast time, when it was 370 miles east of the islands and moving to the east-northeast at 16 mph.
The system is expected to disintegrate several hundred miles west of Portugal, the hurricane center said in its last advisory on Gordon.
At its peak, Gordon was a Category 2 hurricane with winds of 110 mph before cold water weakened it and powerful wind shear tore at its structure. The center said those forces will keep ripping at Gordon until it falls apart.
Gordon was the seventh storm of the six-month Atlantic hurricane season. An eighth system, Tropical Storm Helene, broke up over Mexico on Aug. 18.
The center is tracking three potential storms in the Atlantic basin. A large low pressure system about 1,000 miles east of the Lesser Antilles has an 80 percent chance of becoming tropical in the next two days.
A cluster of storms off the eastern coast of Mexico has a 30 percent chance of developing and one south of the Cape Verde Islands also has a 30 percent chance.
