Un potente temporal invernal azota desde este fin de semana amplias regiones de Estados Unidos y Canadá, con nevadas intensas, temperaturas extremas y fuertes vientos que han provocado el cierre de aeropuertos, carreteras intransitables y miles de incidencias en el suministro eléctrico.

Las autoridades han activado estados de emergencia en varios territorios ante el avance de un frente frío asociado al vórtice polar.
