Firefighters made progress and were helped by improving weather over the weekend in the battle against wildfires covering massive areas in the western United States, but further evacuations have been necessary as thousands of personnel tackle the flames.

The Park Fire, the largest wildfire in California this year, was one of more than 100 large active wildfires burning in the U.S. on Monday. Evacuation orders were in effect on 25 wildfires, according to the National Interagency Fire Center. More than 27,000 wildland firefighters and support personnel are assigned to wildfires that have burned more than 3,200 square miles (8,288 square kilometers) nationwide, the center said.

Some were sparked by the weather, with climate change increasing the frequency of lightning strikes as the western U.S. endures blistering heat and bone-dry conditions.
