Winds in the area were blowing at about 20-30mph (32-48km/h), but could pick up, which would fan the blaze and make it harder for air crews to operate. Climate change has made the grasses and shrubs that are fuelling the Los Angeles fires more vulnerable to burning, scientists have said.

The Hughes fire, which broke out north of Santa Clarita earlier Wednesday, has scorched more than 8,000 acres, according to Cal Fire.
