The Alamo Fire burning between Santa Barbara County and San Luis Obispo County had covered almost 24,000 acres (approx. 97 square kilometers) by Monday, with no casualties reported.
The fire in southern California burned amid record-setting heat and spread rapidly starting Friday. The fire size grew twice as much in every 24 hours on an average. By Monday morning, only 15 percent was contained.
So far, a building has been burnt down and more than 130 buildings have been threatened. Several hundred neighboring residents have been ordered to evacuate the area.
Hundreds of firefighters from nearby counties have been deployed to contain the fire, the cause, however, still remains unknown.
The Alamo Fire is one of 14 wildfires across California, being battled by approximately 5,000 firefighters Sunday, according to an update report about California fire incidents Sunday afternoon.
