The Olympic men's super-G event tomorrow has been brought forward due to a forecast of more warm weather in Sochi.
It has been reported that the temperature on the Rosa Khutor course has risen to about 10 degrees Celsius for the past few days, and is expected to increase further.
The race will now take place at 6am GMT on Sunday, instead of at 7am GMT as originally scheduled.
Warm temperatures in Sochi have already disrupted events and training this week.
