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.
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.
Details: Proper classification helps emergency managers, media, and the public understand the potential impacts of an approaching hurricane and make appropriate preparations.
Tips: Enter the sustained wind speed in miles per hour (mph). The calculator will determine the corresponding hurricane category.
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.
