Hurricane classification is primarily based on the Saffir-Simpson Hurricane Wind Scale, which categorizes hurricanes into five levels. This scale measures sustained wind speeds, with Category 1 being the least severe (winds of 74-95 mph) and Category 5 being the most intense (winds exceeding 157 mph). Each category indicates the potential damage and flooding a hurricane can cause. Meteorologists use various tools, including satellite imagery and weather buoys, to monitor and classify hurricanes. The classification helps in issuing warnings and preparing communities for potential impacts, ensuring public safety during severe weather events like hurricanes.
