Forecasters have downgraded Hurricane Bill to a category 1 hurricane as it makes its way toward the U.S. Coast. Tropical storm warnings are still in effect for the Massachusetts coast and parts of Canada.

Bill has been churning up rough waters this week, creating dangerous rip tides and closing beaches to swimmers up and down the eastern seaboard. Parks officials announced Friday that swimming at Rockaway, Coney Island, Manhattan, Midland, Wolfe's Pond and South beaches is temporarily banned.

Bill, originally classified as a category 3 hurricane, is expected to pass the mainland far off the New England coast. High winds, which are expected to reach the mainland, have safety officials urging caution.

On Saturday night, Bill had maximum sustained winds near 85 mph and was about 300 miles south-southeast of Nantucket, Mass., and about 585 miles south-southwest of Halifax, Nova Scotia.
