New Hurricane Categorization System Improves Public Preparedness

The current Saffir-Simpson Hurricane Wind Scale (SSHWS) solely focuses on wind speed, neglecting the significant threats posed by storm surges and rainfall, which account for nearly 80% of hurricane deaths. This has led to devastating consequences in events like Hurricane Katrina and Florence, where low-category hurricanes caused massive casualties and damage. A new system, the Tropical Cyclone Severity Scale (TCSS), incorporates wind speed, storm surge, and rainfall to provide a more comprehensive assessment of hurricane risk. A study shows TCSS significantly improves public understanding of hurricane dangers and prompts more effective preparedness actions.
