The dull rumble would rise in pitch to a swishing, lashing exultation, causing stalks to lie flat against the ground while the tougher branches of shrubs held themselves up and shrieked their defiance in the gusts. Then the first drops, cold and heavy, would plummet from the sky and burst on the ground.
