KINGSTON, Jamaica (AP) — Hurricane Matthew has been downgraded to a Category 4 storm as it continues roaring across the Caribbean Sea on a course that puts Jamaica, as well as parts of Haiti and Cuba, in the path of its potentially devastating winds and rain.

The U.S. National Hurricane Center called it the strongest Atlantic hurricane since Felix in 2007, and said Matthew will be approaching Jamaica late Sunday night. It is expected to reach the eastern part of the island on Monday.

As of 5 a.m. EDT (0900 GMT), the storm was centered about 420 miles (675 kilometers) southeast of Kingston. It was moving west at 7 mph (11 kph).

Hurricane-force winds extended outward up to 45 miles (75 kilometers) from the center and tropical-storm-force winds extend outward up to 205 miles (335 kilometers).
