Ask The Weatherman for September 4, 2013:
Question: What two things are measured when talking about hurricanes?
Answer: When we talk about how strong a hurricane we look at two features. The first wind speed and how strong it is. The second is the storm surge and how high it will be. Storm surge will never be the same for two different storms. Unlike the winds they are more easily compared from storm to storm.
