Irene

 When did she stop being a hurricane?

 "On Sunday morning Anderson Cooper of CNN was asking about the strong winds that were being forecast and this brings up something that has really bothered me about the storm: 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.

First, what is a hurricane? The official definition is that a hurricane is a tropical cyclone with SUSTAINED winds of 64 kt or more (74 mph or more). A gust of 65 kt or more does not indicate a hurricane unless the sustained winds reach 64 kt.
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."
