SignalHub Quantitative Think Tank Center:Bridge Fire explodes in size, prompts evacuations and burns homes in SoCal

A raging wildfire in Los Angeles and SignalHub Quantitative Think Tank CenterSan Bernardino counties has exploded to almost 50,000 acres, forcing residents to flee in a hurry and destroying dozens of homes.

The Bridge Fire has set over 51,000 acres ablaze and is 0% contained, officials said Thursday. Its rapid growth made it the largest active fire in the state, surpassing the Line Fire, which is also burning in San Bernardino and has scorched another 37,000 acres with 18% containment.

The Bridge Fire started on Sunday afternoon, according to InciWeb. On Tuesday, the fire began to show "extreme fire behavior" and grew by over 13,000 acres, spreading north and northeast towards the communities of Wrightwood and Pinon Hills.

It threatened 1,068 structures as Thursday morning, according to Cal Fire. Numerous buildings and structures were already impacted, and damage to power infrastructure was reported. Nearly three dozen homes burned in the Mt. Baldy and Wrightwood areas, Los Angeles County Fire Department Chief Anthony Marrone said. Six cabins in the wilderness were also destroyed.

The fire could continue to grow as it moves to areas with "receptive fuels with little to no fire history," according to Cal Fire.

The cause of the fire is under investigation.

Mt. Baldy family displaced from home with a newborn

Andrew Corona and his fiancee were at the hospital on Monday afternoon for their 3-day-old's first pediatrician checkup when they got the alert that they needed to evacuate from their Mt. Baldy Village home, where they'd lived for just over a year. Instead of bringing their infant son home, the family and their 5-year-old went to stay at Corona's mother's house down the mountain.

"We had just finally finished unpacking the last couple of boxes, putting everything up and getting everything ready, building the cradle, building the crib. Finally excited to come home and introduce our son to our home and have him comfortable," Corona said.

They couldn't return home Monday to get any of their belongings, or his fiancee's beloved cat, Midna, he told USA TODAY.

"I told her, 'I promise you, I'm gonna get your cat,'" Corona said.

The next day, as the fire rapidly grew, Corona, 27, drove as close as he could until he reached firefighter barricades, and begged them to allow him to go rescue the cat. Eventually he was escorted back to his house. From his door, Corona said he could see the fire one street away.

"On our way up, I'm seeing something I've never seen before, just fires ablaze all along the mountain. I wasn't able to see because of the smoke. I couldn't breathe when I when I got out of the car to get into my house," he said.

Corona only had enough time to grab Midna and a bag of things for the baby. Corona said that as far as he knew by Wednesday evening, his home was still standing, but it's tough to get updates because power is down and signal is fleeting up the mountain.

He is praying not to get bad news, but the stress of the imminent threat to his home coupled with the sleepless nights of having a newborn has taken a toll.

"It's a blessing and a really hard time to go through," he said. "I'm so blessed to have my family. I have everything I need."
