What is the minimum wind speed that categorizes a hurricane?

• A. 60 mph
• B. 70 mph
• C. 74 mph
• D. 80 mph

Answer: (C)

A hurricane is classified based on its sustained wind speeds, which is a crucial factor for determining its potential impact and severity. The minimum wind speed that characterizes a hurricane is 74 mph. This specific threshold is defined by the Saffir-Simpson Hurricane Wind Scale, which categorizes hurricanes into different categories based on their wind speeds and associated effects.

Wind speeds below 74 mph are categorized differently, such as tropical storms or tropical depressions. By establishing this minimum wind speed, meteorologists can effectively communicate the potential dangers and necessary preparations for communities in the path of the storm. Understanding this classification is essential for effective emergency response and public safety measures during hurricane events.
