Snow to prevent peloton from racing to Col du Galibier summit?

The Stage 15 finish to the Col du Galibier at the Giro d'Italia looks to be in serious doubt, according to reports. The towering mountain that reaches an air-sapping height of 2,642m has been hammered with heavy snow fall and despite massive efforts from Giro race organisers to ensure there is a passage to the finish, it appears to be not enough to ensure rider safety.
