Los Angeles County's top emergency manager said Saturday the county's overhaul of its emergency notification system is nearly complete after it sent out a succession of faulty emergency alerts urging millions of residents across Los Angeles to prepare to evacuate amid the ongoing firestorm.

Around 4:15 p.m., another alert was sent out by the the Los Angeles County Office of Emergency Management asking residents to disregard the previous alert, as it was only intended for the Kenneth fire, which erupted near West Hills bordering Los Angeles and Ventura counties earlier in the afternoon.

Emergency evacuation alerts have gone off the rails, pinging people seemingly at random. Experts say that such errors can sow mistrust in the alert system, potentially endangering residents down the line.

Public safety officials fear that residents might ignore future, accurate alerts if they become accustomed to false warnings.

While the message was intended for residents of Woodland Hills, officials say the registration location of the phones might have caused a wider distribution.
