The Saffir-Simpson Hurricane Wind Scale is a system used to categorize hurricanes based on their wind speeds. It ranges from Category 1, with winds of 74-95 mph, to Category 5, with winds exceeding 157 mph. Each category indicates the potential damage a hurricane can cause, helping people prepare for severe weather. This scale is crucial for emergency management and public safety. By understanding the category of a hurricane, communities can take appropriate actions, such as evacuations or securing property. The scale emphasizes the importance of being informed about hurricanes like Hurricane Katrina or Hurricane Harvey, which had devastating impacts.
