To accurately measure the intensity of hurricanes, meteorologists use the Saffir-Simpson Hurricane Wind Scale. This scale is based on a hurricane's maximum sustained wind speed and provides a rating from 1 to 5, with 5 being the strongest. Hurricane Katrina, which made landfall in 2005, was classified as a Category 3 hurricane with maximum sustained winds of 111-129 mph (178-208 km/h).
