• A series of wildfires are raging throughout Los Angeles and Ventura counties in Southern California.
• The three largest blazes - known as the Thomas Fire, the Creek Fire, and the Rye Fire - are burning around Ventura, Sylmar, and Santa Clarita, scorching thousands of acres and showing no signs of stopping as of Wednesday morning.
• More than 200,000 people have been forced to leave their homes, and many areas are under mandatory evacuation orders.

A series of wildfires are burning out of control in Los Angeles and Ventura counties in Southern California.

As many as 200,000 people have been displaced and authorities have closed the 405 Freeway, causing gridlock throughout the region. More than 50 schools were closed on Wednesday in the Los Angeles area.

The first and largest blaze, dubbed the Thomas Fire, started on Monday evening in Ventura County. As of Wednesday morning, it had burned more than 50,500 acres and destroyed at least 150 structures out of at least 12,000 threatened.

The flames have crossed the 101 Freeway near Solimar Beach in Ventura County and have now reached the Pacific Ocean. On Wednesday morning, Caltrans announced a full closure of the 405 freeway between the 101 and 10 freeway, one of the busiest and most congested thoroughfares in Los Angeles. It has also closed all onramps to the 405.

Gov. Jerry Brown has declared a state of emergency, freeing up state funds to help tackle the wildfires.

"This fire is very dangerous and spreading rapidly, but we'll continue to tackle it with all we've got," Brown said. "It's critical residents stay ready and evacuate immediately if told to do so."

Ventura County Fire Chief Mark Lorenzen told reporters that the fires' growth had been "absolutely exponential."
