Vanno davvero da un estremo all'altro le condizioni meteo che si registrano in questi giorni negli Stati Uniti. Washington D.C. è attualmente alle prese con un'ondata di caldo senza precedenti per il mese di ottobre: ben 35° gradi sono stati rilevati ieri nella capitale federale, dove la gente cerca adesso un po' di frescura in una cornice decisamente inconsueta per un inizio d'autunno.
Ma la meteo riserva sorprese anche... agli antipodi. Come nei territori del Montana, nel nord-ovest del paese, dove è invece arrivata la neve, e in quantità copiosa: con una coltre bianca di quasi un metro e mezzo. In queste aree, va precisato, non sono insolite le nevicate già a cavallo fra settembre e ottobre. Ma una simile quantità di neve, sottolineano i meteorologi, rappresenta un dato davvero singolare. Le nevicate, intanto, hanno raggiunto anche lo Stato confinante del Wyoming.
