1. What is the Hurricane Wind Speed Scale?

The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane's sustained wind speed. This scale estimates potential property damage and is used to communicate potential threats.

2. How Does the Calculator Work?

The calculator determines the hurricane category based on sustained wind speed:

Category 1: 74-95 mph

Category 2: 96-110 mph

Category 3: 111-129 mph

Category 4: 130-156 mph

Category 5: 157+ mph

Explanation: The scale provides an estimate of potential property damage, with Category 1 being minimal and Category 5 being catastrophic.

3. Importance of Hurricane Classification

Details: Proper classification helps emergency managers, media, and the public understand the potential impacts of an approaching hurricane and make appropriate preparations.

4. Using the Calculator

Tips: Enter the sustained wind speed in miles per hour (mph). The calculator will determine the corresponding hurricane category.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a "sustained" wind speed?
A: Sustained winds are defined as the average wind speed measured over one minute at 10 meters (33 feet) above the surface.

Q2: Does this scale consider other hurricane hazards?
A: No, this scale only considers wind speed. Storm surge, rainfall flooding, and tornadoes are not included but can be equally dangerous.

Q3: Can a Category 1 hurricane be dangerous?
A: Yes, all hurricanes can produce life-threatening conditions through storm surge, inland flooding, and tornadoes.

Q4: What's the difference between mph and knots?
A: 1 knot = 1.15078 mph. The National Hurricane Center typically uses knots for measurements but converts to mph for public advisories.

Q5: How often is this scale updated?
A: The Saffir-Simpson scale has remained largely unchanged since its creation in the 1970s, though minor adjustments have been made.
