"A handful of super powerful tropical storms in the last decade and the prospect of more to come has a couple of experts proposing a new category of whopper hurricanes: Category 6.
Studies have shown that the strongest tropical storms are getting more intense because of climate change. So the traditional five-category Saffir-Simpson scale, developed more than 50 years ago, may not show the true power of the most muscular storms, two climate scientists suggest in a Monday study in the Proceedings of the National Academy of Sciences. They propose a sixth category for storms with winds that exceed 192 miles per hour (309 kilometers per hour).
Currently, storms with winds of 157 mph (252 kilometers per hour) or higher are Category 5. The study’s authors said that open-ended grouping doesn’t warn people enough about the higher dangers from monstrous storms that flirt with 200 mph (322 kph) or higher."
