California Gov. Gavin Newsom declares a state of emergency in Orange County following a toxic chemical incident at a Southern California aerospace facility in the Garden Grove area. Officials report that a damaged chemical tank is at risk of leaking or exploding, prompting evacuations and extensive emergency operations. Multiple outlets say that tens of thousands of residents are ordered to leave, with figures cited around 40,000 to more than 50,000, and that the evacuations affect a densely populated region near Disneyland. State and local responders work to neutralize or divert the threat from the tank, including an overnight effort reported by Fox News. The state proclamation directs California’s Office of Emergency Services and other state agencies to provide additional support to Orange County responders, including making state-owned properties available to shelter evacuees. France 24 reports that authorities discover a crack in the damaged tank and later describe reduced concerns about a potential explosion. Separately, New York Post reports that President Trump issues a federal emergency declaration after state officials raise concerns about the situation escalating.
