What we know about California wildfires: 31 deaths, more than 6,700 structures destroyed

The images and stories from the wildfires raging in Northern and Southern California present a picture of a rampaging inferno spreading at dizzying speed.

The numbers behind those hellish scenes are just as somber.

Here’s what we know so far about the devastation inflicted upon the country’s most populous state.

To the south in Los Angeles and Ventura counties, the Woolsey Fire has brought an extra layer of grief to an area stunned by Wednesday’s mass shooting at the Borderline Bar and Grill, which left 13 people dead, including the gunman. This blaze has scorched more than 83,000 acres and is just 10 percent contained.

The Hill Fire, also in Ventura County north of Malibu, has burned 4,500 acres and is 70 percent contained.
