As I mentioned earlier, only three Atlantic hurricane seasons other than this one have recorded more than one Category 5 storm. Those seasons are 1960 (Donna, Ethel), 1961 (Cleo, Hattie), and 2005 (Emily, Katrina, Rita, Wilma). But here's what makes 2007 distinct: Each of the year's first two storms to reach hurricane strength have also reached Category 5 hurricane strength. You certainly don't see such a phenomenon with any of these other years. I'm not sure exactly what to make of this particular record, but it seems unlikely to be equaled any time soon.
