What's weirder about last year's Igor, Julia, and Karl is Julia lived entirely within Hurricane Igor's livespan, and Karl lived entirely within Julia's. Igor lasted from September 8-21, Julia lasted from September 12-20, and Karl lasted from September 14-18. Julia, in other words, was born after and died before Igor, and Karl was born after and died before Julia. That's strange, and such an event may have never been recorded before, or very rarely, at least.
