Having already moved the sprint to Sunday and instead holding the main race of the weekend on Saturday in anticipation of bad weather, organisers abandoned efforts to hold the 13-lap race just half an hour before the scheduled start time of 1pm local time.
It followed the earlier Moto2 race that was red-flagged after just nine of 23 laps were completed, with 10 of the 30 starters crashing in that time in the treacherous conditions.
