Large wildfires ignited in California, Montana, Oklahoma, Oregon and Texas on Sunday, bringing the total number burning across the U.S. to 53, according to firefighting agency data.
The big picture: A report from the National Interagency Fire Center (NIFC) Sunday indicates the worst may be yet to come, with the "potential for lightning followed by a heat wave across the northern half of the West." This "could increase the potential for significant fire activity," per the NIFC.
