Are there any English words that mean "an unlikely calamity" in that same way that "miracle" can mean "an unlikely beneficial event"? My thesaurus only provides antonyms of "miracle" that mean "a mundane event" rather than "a horrible event".
I'm thinking specifically of multiple unlikely failures occurring simultaneously: I suffer an unlikely injury that leaves me unable to leave the house and my usually-reliable telephone service suddenly cuts out for the day, so I can't phone for help.
Words like "catastrophe" and "calamity" seem too general, since I'd like to express the exceptional unlikelihood of the event (or events). The best I have is a descriptive phrase like "disastrous coincidence," but I'd prefer a single word.
Overtones of the divine or demonic are not required, but preferred.
