A host of Olympic freestyle skiing training sessions in Sochi had to be cancelled on Friday due to unseasonably high temperatures.
With temperatures reaching 15 degrees Celsius, the International Ski Federation (FIS) decided to call off the first ski cross training session in the early afternoon (2.30pm local time, 1030 GMT).
"Given the high temperatures and thermal stress on SX (ski cross) course, it is not wise to train today," said FIS race director Joseph Fitzgerald in an official statement.
The weather will not affect competition schedules with the women's aerials due to begin at its scheduled time of 5.45pm (1345 GMT) on Friday but the men's aerials training sessions on Saturday and Sunday were pushed back to a later start time.
And the women's ski halfpipe training on Saturday was called off altogether, although Sunday's session will go ahead.
