Residents were already on edge as more fires erupted across the Los Angeles region, traumatising millions of people who feel that after four days there’s no end in sight.Then on Thursday afternoon came another jolt in the form of a text alert.This one was mistakenly sent to every cell phone in the county – home to about 10 million people – warning them the blaze was close and they should prepare to evacuate.Rebecca Alvarez-Petit was on a video work call when her phone started blaring. “An EVACUATION WARNING has been issued in your area,” the text message said.The sound echoed around her as each of her colleagues received the same startling message.”It was like a massive panic that I was watching in real-time,” she said.She and colleagues started researching and trying to see whether they were in imminent danger.

Of course,” Mayor Bass said, answering a question about water issues and whether the area was prepared enough. She noted that is an “unprecedented event”.Like other officials, she stressed the fires were able to spread on Tuesday because of strong winds – the same winds that prevented aircraft from dropping water or fire retardant on the blazes. She said urban water systems and neighbourhood fire hydrants are not built to handle dousing thousands of acres of fire.She noted there will be reviews of how the incident unfolded that will examine how officials and agencies handled it.”When lives have been saved and homes have been saved, we will absolutely do an evaluation to look at what worked, what didn’t work, and to correct or to hold accountable any body, department, individual,” she said. “My focus right now is on the lives and on the homes.”W …
