The Saffir-Simpson scale increases in category for every 20 miles per hour. They aren't called hurricanes not because north Pacific storms aren't as strong or stronger than many hurricanes, but because they are not tropical in character. What is the proper order of storm intensity in terms of increasing wind speed? To be considered a hurricane, a storm must be characterized by low pressure and rotation with the incidence of organized thunderstorms. b. c. 64 miles per hour.
