Dial it up to Category 6? As warming stokes storms, some want a bigger hurricane category

The traditional five -category Saffir-Simpson scale, developed more than 50 years ago , may not show true power of the most muscular storms, two climate scientists suggest.

They propose a sixth category for storms with winds that exceed 192 miles per hour ( 309 kilometers per hour ) Since 2013 , five storms—all in the Pacific —had winds of 192 mph or higher that would have put them in the new category.

Former FEMA Director Craig Fugate and University of Albany atmospheric sciences professor Kristen Corbosiero say they don't see the necessity for a sixth and stronger storm category.

"Perhaps I'll change my tune when a rapidly intensifying storm in the Gulf achieves a Category 6 ," Corbosieo says.
