The western United States is continuing to deal with forest fires.

A vegetation fire, dubbed the Sand Fire, in Northern California's Yolo County, which began on Saturday, has grown rapidly, reaching 1,700 acres with no containment. The fire is reportedly threatening several structures and caused the closure of the area's main highway. Some residents have been ordered to evacuate.

Meanwhile, in Arizona's Tonto National Forest, a human-induced fire, which is being called the Mountain Fire, is moving swiftly, aided by strong winds that have made it difficult for firefighters to contain. That fire, which was first reported on Friday, has now burned about 7,225 acres in the national forest, which is northeast of Phoenix. Tim O'Donnell
