Recently I noticed that a storm map says 156+mph winds for a category five hurricane. A few days ago It said 155+mph winds. Which Is True? 155 or 156?

MIKE MOSS SAYS:       Daulton,      The Saffir-Simpson scale is divided by wind speed such that 155 mph is the top value for a Category Four storm, while 156 mph is the lowest value for a Category Five.
