California declaring a state of emergency in Los Angeles and San Bernardino counties take a look as three major fires are destroying homes. Scorching more than 100,000 acres, gusty winds that were blowing wildfires out of control will finally begin to calm down later today. And A B C's Melissa A Don is in San Bernardino County with the latest on those fire conditions. State of emergency for several southern California counties after three major wildfires burned more than 100,000 acres across four counties in the mountains of Los Angeles and San Bernardino counties. The bridge fire has scorched more than 50,000 acres. The largest act of wildfire in California. It was pretty scary a lot. It's a lot more thrilled than you can realize when you're outside looking at the flames. You don't realize how scary and how chaotic it is. More than 30 homes were destroyed by the bridge fire including this one. You can see what was their kitchen and oven. Some cabinets there incinerated in Riverside county, the fast moving airport fire forcing more than 19,000 people to quickly evacuate. We packed up the kids and got out of there not couple hours later, we heard our house was just leveled in the mountains an ominous picture. The line fire turning the sky orange as firefighters make progress on the fight. After a break from an intense heat wave flames in the ash was falling and it was just hard to breathe. Authorities arresting a 34 year old man suspected of starting the line fire. I can assure the public that we're going to go hard on this case, that we're going to be resolute on this case. And again, it's a developing situation that we hope does not get any worse. The National Guard is working to assist first responders as more than 100,000 people have been displaced from their homes. This as fire crews work to contain those flames. Melissa Don ABC News, San Bernardino County, California.
