An Etymological Dictionary of the German Language/Annotated/Windsbraut
Windsbraut, feminine, ‘hurricane, tornado,’ from the equivalent Middle High German windes brût, Old High German wintes brût, feminine; a remarkable formation, which is usually referred to mythological ideas. Yet Old High German and Middle High German brût in this compound might be cognate with Middle High German brûs, Modern High German Braus, if this were connected with pre-Teutonic bhrût-to-.
