Is there any alternative descriptive phrase for, "The perfect storm"?

I just heard a caller on NPR use the phrase. Typically you’ll hear it from talking heads on the television. Is it just the nature of media? will this buzzword ever pass? If so, then with what – retro buzzword “synergy”? <sigh>

defined by wikipedia:
The phrase perfect storm refers to the simultaneous occurrence of events which, taken individually, would be far less powerful than the result of their chance combination. Such occurrences are rare by their very nature, so that even a slight change in any one event contributing to the perfect storm would lessen its overall impact.
