California Governor Jerry Brown declared a state of emergency for the Holy Fire on Thursday, KABC-TV reported.

The fire was allegedly ignited by Forrest Gordon Clark, 51, who was booked into Orange County Jail on Wednesday. Clark is facing two counts of felony arson, one count of felony threat to terrorize and one count of misdemeanor resisting arrest, officials confirmed to KABC-TV. He is currently being held on $1 million bail.

Clark allegedly sent a text message to a fire chief that read "This place is going to burn" two weeks ago, CNN reported. The 51-year-old reportedly owns the only home in the area that was not destroyed by the fire, The Orange County Register reported. Clark refused to make his appearance in court on Thursday on Thursday and his arraignment has been rescheduled for Friday, The Sacramento Bee reported.
