Weathermen

The Weathermen, also known as the Weather Underground Organization, was a US-based, self-described "revolutionary organization of communist men and women" formed by former members of the defunct Students for a Democratic Society (SDS). It was active from 1969 to 1976.

The name of the group derives from the Bob Dylan song "Subterranean Homesick Blues", which featured the lyrics, "You don't need a weather man to know which way the wind blows", quoted at the bottom of an influential essay in the SDS newspaper, New Left Notes.
