We keep hearing that Sandy is a Category One hurricane, but at the same time, we're told not to treat it lightly. It could be because of the way hurricanes are rated in the first place.
It’s called the Saffir-Simpson Hurricane scale. It was developed in 1971 by civil engineer Herbert Saffir and meteorologist Bob Simpson, who was the director of the National Hurricane Center at the time. The idea was to give the public an idea of the destructive force of a hurricane in a simple way, a lot like the Richter Scale rates earthquakes.
