Claim: Hurricane Sandy Was 1-in-700-Year Event — phew, glad that’s over with

LiveScience reports:

Except that New York City has an extensive history of hurricanes/flooding.

  1. I think he is going overboard. Yes, Sandy’s specific path might be a once per 700 years track, but a hurricane hitting NYC is more of a once per 40 year event, and being affected by a hurricane is a once per 20 years.

    Just as in statistics class. You don’t care how you get dealt a royal flush, you just care that you got one.

  2. Yeah hurricanes never happen in New England

    1938 Hurricane slams East Coast

    1938 newsreel. A hurricane of 1938 (later dubbed “The Long Island Express) rips through the eastern states leaving behind a trail of devastation and killing 600 people.

  4. Then there was the time when I-25 was under construction and a flash flood washed out a newly installed structure plate pipe culvert. The experts evaluated the situation and declared it was a 500 year flood, so they replaced it. About two weeks later another “500 year flood” took it out.

    Agnes 1972
    1933 HURRICANE
    I have done talks for years to insurance companies and blogged on why a storm from the se was going to happen, except that the biggest worry would be PHL and WIL. due to storm surge up Delaware bay, while flooding from river was coming coming down to meet it. This storm was long overdue and was caused by the same vigorous upper pattern that drove 1954 hurricane Hazel into the Carolinas, only that was a cat 4 when it hit
    More hysteria from people who have not looked and are nothing more than climatic ambulance chasers

  6. For an every-700-year event, it seems to have happened three or four times in the last hundred years.
