The acronym story popped up in a local paper under the name of one Bob Ogley, who usually does local history and published books about the 1987 hurricane and Biggin Hill, among other things. I wrote to him, unaware of Snopes, but possessing an Anglo-Saxon dictionary, which gave "scite" as meaning what it means - the German connection predates the German use of z where English uses t. I never had a response.
