It’s peak wildfire season in California, and Monday was one of the worst days in state history. More than 60 blazes are currently underway statewide.

At least a dozen wildfires sprung up Sunday night in and around Napa and Sonoma counties — also known as “wine country,” just north of San Francisco — prompting rushed evacuations of more than 20,000 people. In an attempt to speed the flow of relief and firefighting equipment and make the National Guard available, Governor Jerry Brown has declared a state of emergency.

The Northern California firestorm has quickly burned nearly 100,000 acres, and is encroaching on neighborhoods in several places. At around 3 a.m. Monday, a Cal Fire official told a local television station that there was “no hope of containment right now.”

In total, the fires have killed 13 people and destroyed more than 1,500 structures as of Tuesday morning, making them some of the most destructive in state history. More than 100 people have been treated for burns and smoke inhalation at regional hospitals, according to the San Francisco Chronicle, and more than 150 people are still missing. Nationwide, this year’s fire season has cost more than $2 billion, the most expensive on record.
