Hurricanes' strength is measured by the Saffir-Simpson scale. What is this, you ask?
The Saffir- Simpson scale is...
the scale used to measure the severity of hurricanes.
That's simple, right? Maybe you've heard people say on the news "category 3", "category 5", or maybe even "category 52" (Okay, that's impossible. Get the point, though?). How is this measured, though? It has to do with wind speed(self explanatory, right?0) and storm surge(according to Answers.com:"A rise above normal water level on the open coast due only to the action of wind stress on the water surface; includes the rise in level due to atmospheric pressure reduction as well as that due to wind stress. Also known as storm wave; surge.") Look at the graph and it will probably make sense to you.
