UK: The Shorter Oxford Dictionary states: ‘A violent disturbance of the atmosphere, manifested by high winds, often accompanied by heavy falls of rain, hail or snow, by thunder and lightning and (at sea) by turbulence of the waves. Hence sometimes applied to a heavy fall of rain, hail, or snow, or to a violent outbreak of thunder and lightning, unaccompanied by strong wind’.
