Where did the hurricanes go?

Wunder Blog : Weather Underground: "Quietest September in the Atlantic since 1997
Well, it's the end of September, and what is traditionally the busiest month in the Atlantic was unusually quiet. We had only two named storms this September, the first time since 1997 we've had less than three September named storms. There were only 6.75 days in September with a named storm, which ranks as the 4th fewest September named storm days since 1950 (only 1962, 1970, and 1994 had fewer). The Accumulated Cyclone Energy (ACE) index for September ranked as the 6th lowest since 1950. The quiet period is likely to continue for at least another week, as there are no threat areas in the Atlantic to discuss today, and none of the computer models are forecasting tropical storm formation over the next seven days. I'll post my first-half-of-October outlook for the Atlantic tomorrow."

Comment -- Over the short term, weather is never "normal". It's only "normal" when you average it over long time spans. I guess you could say it's normal for weather to vary a lot!

Frost is predicted in mid-Michigan tonight. That may seem kind of early, but it appears that the earliest frost ever was Sept. 5 1997 (http://www.crh.noaa.gov/grr/history/?m=9).
