(AP) – Authorities are bracing for the possibility that a damaged chemical tank at a facility in Southern California could leak or explode. An evacuation order has continued into the Memorial Day weekend for 40,000 residents of Garden Grove and several surrounding communities with no timeline on when they can return. No injuries were reported after the pressurized tank began overheating Thursday. Firefighters hope to find a way to cool off the chemical inside the tank so it won’t leak or explode. Experts say a leak would be much better than an explosion. Gov. Gavin Newsom has declared a state of emergency in Orange County. Several shelters remain open, including at three schools. (Photo: AP)
