“This looks pretty, pretty concerning,” said meteorologist Daniel Swain.
“It’s going to be, I think, a rough night. And what’s going on now is only just the beginning, because weather conditions are going to get a lot worse.”
With a huge pall of smoke visible over the whole of Los Angeles, events throughout the area were cancelled, including a red-carpet premiere of Jennifer Lopez’s new film “Unstoppable.”

“No politics, no hand wringing, no kissing the feet. The president of the US said, ‘Yes. What else do you need?'” he told reporters.
Incoming president Donald Trump has previously threatened to withhold wildfire aid from Democrat-ruled California.
