Hurricane Igor

MIAMI, Sept 12 (Reuters) - Hurricane Igor strengthened over the Atlantic Ocean on Sunday but posed no immediate threat to land or energy interests.

The U.S. National Hurricane Center said Igor, located about 1,145 miles (1,840 km) east of the Caribbean's northern Leeward Islands, was now a Category 2 storm on the five-step Saffir-Simpson scale of hurricane intensity.

It was churning toward the west with top sustained winds of 105 miles (165 km) per hour, the Miami-based hurricane center said.
