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.

Weather conditions triggered red flag warnings in the northeast part of the United States as firefighters in California continued to battle a large wildfire that has burned over 20,000 acres.

The Jennings Creek fire is currently burning across 3,500 acres, officials said, and is expected to grow to over 5,000 acres.
