A heat wave was developing in California on Monday but winds were light as firefighters battled a wildfire that poses a threat to a grove of giant sequoias and a small community in Yosemite National Park.
The Washburn Fire on the western flank of the Sierra Nevada had scorched about 3.6 square miles by Monday morning, an increase of about 300 acres (121 hectares) overnight, according to an incident update.
