Roads turn into white rivers of ice in French town as storms bring summer to an end

Roads in the Alpine town of Gap were left looking like white rivers of ice after a freak supercell storm pounded the area with giant hail, torrential rain and winds reaching 90km/h. The Hautes-Alpes community, usually filled with late-summer holidaymakers, was battered by the extreme weather system that Météo-France calls 'the most violent and devastating type of isolated storm.'
