Linguistic Origin & Historical Etymology

The term is a modern compound formed from the native English words 'storm' (derived from Proto-Germanic *sturmaz, meaning tumult or storm) and 'water' (from Proto-Germanic *watōr). It emerged in environmental science and civil engineering during the mid-20th century to specifically designate precipitation that falls during storms and accumulates on urban or modified land surfaces.
