jamesl writes "Cliff Mass, a climate researcher at the University of Washington and popular Seattle blogger, asks, 'When did Irene stop being a hurricane? ... there is really no reliable evidence of hurricane-force winds at any time the storm was approaching North Carolina or moving up the East Coast. ... I took a look at all the observations over Virgina, Maryland, Delaware, New Jersey, and New York. Not one National Weather Service or FAA observation location, not one buoy observations, none reach the requisite wind speed. Most were not even close. ... Surely, one of the observations upwind of landfall, over Cape Hatteras or one of the other barrier island locations, indicated hurricane-force sustained winds? Amazingly, the answer is still no.' Cliff supports his statement with data from NOAA/NWS/NDBC presented in easy to understand charts."
