Study proposes new hurricane scale incorporating storm surge and rainfall risks, potentially adding Category 6

Summary

A study proposes a new hurricane categorization system that would incorporate storm surge and rainfall risks into the classification scale, addressing a major gap in the current Saffir-Simpson Hurricane Wind Scale (SSHWS). Storm surges and rainfall cause nearly 80% of hurricane-related deaths but are not accounted for in the existing wind-only scale. The proposed system could include a Category 6 designation and aims to better communicate the full spectrum of hurricane hazards to the public, potentially improving preparedness and reducing fatalities.
