A fire that broke out in California and has so far burned almost 3,000 hectacres of woodland was caused by a gender-reveal party, authorities said.

On Saturday, a "smoke generating pyrotechnic device, used during a gender reveal party" sparked a fire in the El Dorado Ranch Park in Yucaipa, the California Department of Forestry and Fire Protection (CAL FIRE) said in a statement on Sunday.

The fire has since spread north to Yucaipa Ridge, prompting evacuation orders to be enforced on Oak Glen, Yucaipa Ridge, Mountain Home Village, and Forest Falls.

"With the dry conditions and critical fire weather, it doesn't take much to start a wildfire. Those responsible for starting fires due to negligence or illegal activity can be held financially and criminally responsible," the statement said.

As of Monday morning, only 5% of which has been contained, according to a tracker from CAL FIRE.

The fire is one of three currently raging across parts of the state. On Sunday, governor Gavin Newsom declared a state of emergency for five counties.
