The U.S. National Hurricane Center in Miami says Edouard has top sustained winds of 40 mph, with higher gusts. It was located late Sunday night about 685 miles south-southwest of Cape Race, Newfoundland, Canada.
The tropical storm is expected to become a post-tropical storm on Monday as it continues to move northeast through the Atlantic. No coastal storm watches or warnings are in effect. A hurricane researcher says Edouard is the earliest fifth named storm on record.
Two named storms formed in the Atlantic before the official start of the hurricane season June 1.
