An emergency alert issuing an evacuation warning for all of Los Angeles County was sent out by accident, according to officials.   "I have been informed the evacuation warning that many of us just received on our phones was mistakenly issued countywide due to a technical error," County Supervisor Janice Hahn wrote on X. "A correction will be issued shortly." Another statement from Hahn stated that the alert was only supposed to go to residents impacted by the Kenneth Fire in West Hills. City officials from Santa Monica, Long Beach and other areas took to social media to reiterate that the message was sent in error.
