There are people across the United States, known as survivalists or preppers, who're actively taking steps to survive a nuclear apocalypse, government collapse, etc. Some of these people are just learning basic wilderness skills while others are very obsessed: building bunkers and stockpiling food, guns, gold, etc. Preppers makeup a tiny percent of the US population, but they've been around for decades. There are already hundreds, if not thousands, of tiny bunkers across the country today.

So, "How could that family know there was a nuclear holocaust coming?", they didn't – they were just preppers.
