Extreme heat-fueled wildfires rage in the West, squeezing California's power supply

Los Angeles — Much of the western United States was still baking on Monday morning as a blistering heat wave continued, fueling wildfires that were forcing evacuations in northern California. Some 30 million people were under excessive heat warnings and advisories on Monday, with multiple cities hitting record-high triple-digit temperatures and the fires turning deadly.

Federal investigators were looking into the crash of a fire survey plane in Arizona, which left retired fire chief Jeff Piechura and his pilot dead. CBS News lead national correspondent David Begnaud reported from Los Angeles that officials were keeping a very close eye on how the blazes could impact California's power grid. Fires in Oregon knocked-out three major power transmission lines to California.
