California's Madre Fire sparked in the late evening of July 3 but has since grown to the largest in the state this year by the Fourth.

The Madre Fire in central California expanded to 70,800 in two days, making it the largest wildfire this year in California.

A fast-moving California wildfire exploded to become the state’s biggest of the year, forcing evacuations and the closure of a highway, and evoking memories of the devastating blazes that laid waste to parts of the state in January.
