The Madre fire burning in San Luis Obispo County has grown to become the largest wildfire California has seen this year. It comes after Southern California was ravaged by wildfires in January, which resulted in the widespread destruction of homes and the deaths of at least 29 people.

The fire sparked in the Los Padres National Forest in San Luis Obispo County and was growing exponentially, officials warned. The area is mostly uninhabited.

The Madre Fire became California's largest blaze so far this year, ripping through grasslands after breaking out Wednesday in southeastern San Luis Obispo County. It swiftly grew to more than 82 square miles (212 square kilometers). It was just 10% contained by Thursday evening.
