The fires burned at least 649,054 acres in the 14 states where fires are still spreading, according to the NIFC.
Some 45 million people remain under some kind of hot warning as advice, and by the weekend no delay of the record hit in the West is expected.
Most of California and some surrounding areas are under too much warning about heat from the National Water Service.
Here’s where the largest of the fires has been reported since Tuesday night, according to the NIFC, which counts area fires as complexes, not as a single fire. These numbers will be updated as soon as new data becomes available.
