This particular usage originated with Sebastian Junger in his non-fiction book The Perfect Storm, published 1997, about an actual event now known as the 1991 Perfect Storm - only it wasn't called that at the time, since the expression hadn't yet been coined.
Wikipedia's definition is as good as any...
A "perfect storm" describes an event where a rare combination of circumstances aggravate a situation drastically.
OP's cited usage is at least quirky, if not misguided. In all normal contexts, anything described as a "perfect storm" is likely to have catastrophically bad consequences. One commonly hears it today in hypothetical scenarios beloved of TV "documentaries", where the impact of some potentially foreseeable disaster can be made far greater by imagining that several unlikely circumstances might all arise at the same time.
