Introduction

Today there is a CNN headline that gives some predictions about the 2013 hurricane season.  Click here to read the story.  This reminded me of the hurricane data that I worked on recently, using Tableau to investigate spatial and temporal trends over the past 40 years.

If you want to examine the data for yourself and to see the trends and my analysis, you can access my Tableau public copy of this work by clicking here.

Data Source

rI used a 40-year hurricane data set during a recent Tableau training course I taught.  Afterwards I thought I’d look a little deeper into whether Hurricanes are increasing in intensity and/or frequency.  What I found out surprised me a little.  I had a feeling that due to global warming trends that more hurricanes would be occurring, with greater intensity.  I didn’t see that with this data.  In fact, it looks like hurricane intensity during this 40-year record peaked in the 1990’s.  I also found out that August and September are the most intense hurricane periods for the east coast of the US.  I won’t be taking any cruises into the Gulf of Mexico or the Caribbean during these months!
