Protect America with structural integrity, Roger Pielke, Jr., June 9, 2014
In 1933, Richard Gray, a U.S. government weather forecaster, noted that Florida had been hit by at least 37 hurricanes over the 45 years ending in 1930. During this period, the longest stretch with no tropical storms was only two years.
When the 2014 hurricane season officially began on June 1, the Sunshine State had gone more than eight years without being struck by a hurricane. It was back on Oct. 24, 2005, when Hurricane Wilma emerged from the Gulf of Mexico and caused billions of dollars in damage in South Florida. In fact, Wilma was the last Category 3 or stronger storm to hit the USA.
The 3,151 days and counting with no Florida hurricane and no major U.S. hurricane shatters the previous records for hurricane “droughts,” at least back to the turn of the previous century. In fact, from 1900 through 2013, the United States experienced a decrease in hurricane landfalls of more than 20%, and the strength of each year’s landfalling storms has also decreased by more than 20%.
Seasons highly variable
Even so, I’d caution against putting too much significance on these numbers, as North Atlantic hurricane seasons are highly variable. In fact, the choice of time period makes a difference. For instance, starting the analysis in 1970, at the lowest point of 20th century hurricane activity, leads to an increasing trend. Read more…
