There is a fascinating study in 538 where author Matt Lanza asks what happens when the (amazing) ten year drought of major hurricanes to hit the United States ends.
You might ask, "what's the big deal since emergency management people will tell us what to do?" I did an informal survey at an EM meeting to which I spoke in Ft. Worth and found there has been tremendous turnover in their ranks along the Gulf coast. We are losing "institutional memory" fast. It is possible that may lead to less than optimal decisions when a major hurricane looms.
While we have another month when a major hurricane might form and hit the U.S., there is nothing out there now. So, more likely than not, we will go into an eleventh straight hurricane season without a Cat 3 hurricane or stronger to come ashore in the USA. We may need to begin thinking about institutional memory before the loss becomes greater.
