11/29/12 Hurricane Season Recap

Technically, hurricane season does not end until tomorrow, but with no potential storms in the Atlantic or Gulf right now, let’s look at a season recap.

Tracks of all tropical systems in 2012
 
This year, we had a total of 19 named storms, 10 of which made it up to hurricane strength (74mph+). However, we had no Category 4 or 5 hurricanes in the Atlantic/Gulf, and we had only one Category 3 hurricane. So how does this compare to average years? Normally we have only 12 named storms a year with the number of storms making it to hurricane strength around 6. However, the number of major hurricanes, which is a Category 3 or higher (111mph+), is typically 3 per year. This year we only had one, Hurricane Michael, which stayed over the open Atlantic. This year also produced the least number of major hurricanes in a season since 1997, when there was only one Category 3, Erika. If that wasn’t enough, we've only seen two years with no Category 4 or Category 5 hurricanes since 1995: 2006 and 1997.
Hurricane Sandy Track
The ironic part of this season is that we started off with a bang, leaving many wondering if this would be a sign of the rest of the season. In May, before hurricane season officially begins in the Atlantic/Gulf, two storms, Alberto and Beryl, had developed. Both only became tropical storms, and both had very little impact on the U.S. Also, this is the seventh consecutive year that no major hurricanes (Category 3, 4 or 5) have hit the United States.
Hurricane Isaac
 
Of course, the caveat is that it doesn't take a major hurricane to cause big damage. Look at Isaac and Sandy, both of which caused devastating floods, along with high winds that caused numerous power outages.
