Strengthening winds and bone-dry conditions were hindering firefighters working to gain control of a stubborn wildfire burning in a forested stretch along the New York-New Jersey state border about 50 miles (80 km) northwest of New York City.

A wildfire that's consumed thousands of acres is only 10% contained after rains helped firefighters control some of the flames.
