(Reuters) - The eye of the potentially catastrophic Category 5 hurricane Irma has moved away from Barbuda and is heading towards St. Martin, the U.S. National Hurricane Center said in an advisory. Hurricane Irma is about 145 miles (235 km) east of St. Croix with maximum sustained winds of 185 mph (295 km/h), the NHC said. The core of Irma is likely to move over portions of the northern Leeward Islands, and move near or over portions of the northern Virgin Islands on Wednesday, it said.
