ORLANDO, Fla./MIAMI, Oct 6 (Reuters) - Matthew, the first major hurricane threatening a direct hit on the United States in more than 10 years, closed in on Florida on Thursday after killing at least 339 people in Haiti on its destructive march north through the Caribbean.
Carrying extremely dangerous winds of 130 mph (215 kph), the storm pounded the northwestern part of the Bahamas en route to Florida's Atlantic coast, the U.S. National Hurricane Center said.
Matthew's top sustained winds had dropped to 130 mph by Thursday night. But it remained a Category 4 on the five-step Saffir-Simpson scale of hurricane intensity as it neared Florida, where it could either plow inland or tear along the Atlantic coast through Friday night, the Miami-based center said.
