A damaged chemical tank in Southern California may have cracked - potentially lowering the risk of a cataclysmic explosion - though an evacuation order remains in effect for some 50,000 area residents with no timeline on when they can return, fire officials said Sunday.
TJ McGovern, the interim fire chief for the Orange County Fire Authority, said in a video posted on social media that fire officials were able to evaluate the tank more closely overnight and spotted a potential crack that could be relieving some of the pressure inside. But he cautioned that the information is still being vetted and validated.
