HELLO GOREONS….HURRICAN SEASON LOWEST IN 110 YEARS

2010 Hurricane Factoids

Adam Lea, of University College London, shares these interesting hurricane factoids related the the remarkable dearth of US hurricane landfalls in recent years.  His comments are reproduced here with his permission:

As the 2010 hurricane season (with 10 hurricanes) starts to wind down I thought I would share a few statistics on how unusual this season has been historically for its lack of US hurricane landfalls:

1. Since 1900 there is no precedent of an Atlantic hurricane season with 10 or more hurricanes where none has struck the US as a hurricane. The five previous seasons with 10 or more hurricanes each had at least two hurricane strikes on the US.

2. The last precedent for a La Nina year of the magnitude of 2010 which had no US-landfalling hurricane is 1973.

3. Since hurricane Ike (2008) there have been 16 consecutive non US-landfalling hurricanes. Such a  sequence last happened between Irene (1999) and Lili (2002) with 22 consecutive non US-landfalling hurricanes, and between Allen (1980) and Alicia (1983) with 17 consecutive non US-landfalling hurricanes.

4. The period 2006-2010 is one of only three 5-year consecutive periods without a US major hurricane landfall (the other two such periods were 1901-1905 and 1936-1940). There has never been a six year period without a US major hurricane landfall.

5. Historically one in four Atlantic hurricanes strike the US as a hurricane. Thus the recent dearth in strikes should be ‘corrected’ in the next few years.
