Data Visualization: Hurricane Irene vs Katrina, Wilma, Rita

Here’s Hurricane Irene, showing wind speeds every six hours, as tracked by the National Hurricane Center. She reached Category 3 status over the Caribbean Islands – a respectable 120 mph storm – but was down to a Category 1 hurricane by the time she reached North Carolina.

How does Irene compare to Hurricanes Katrina, Wilma and Rita, the famous swarm of Category 5 hurricanes from 2005?

These slides come from my SlideShare project “50 Years of Fury”, which studies 50 years of hurricane data to answer the question: are hurricanes getting worse because of global warming. View it here. It’s a good example of many of my principles in action.
