As Hurricane Melissa barrels toward Jamaica as a Category 5 storm, some in the meteorological community are questioning if the traditional way of measuring hurricane strength still tells the full story.

Zachary Handlos, director of the Atmospheric and Oceanic Sciences Undergraduate Degree Program at Georgia Tech, believes it might be time to rethink how we classify hurricanes. While the Saffir-Simpson Hurricane Wind Scale, which rates storms from Category 1 through 5 based solely on maximum wind speed, has been used for decades, Handlos says it doesn’t always capture a storm’s true impact.

“You don’t have to be a tropical cyclone expert to know that the scale has some limitations,” Handlos said. “It doesn’t necessarily portray how strong or impactful a hurricane can be beyond its wind speed.”
