Temperatures of 15 Celsius (59 Fahrenheit) and sunny skies softened the snow in the landing area, forcing organizers to cancel the first of three jumps. The second session was postponed after an official said the first competitor fell while landing.
The same hill will be used for the last scheduled women's ski jumping training later Monday and the first women's final on Tuesday.
Competition manager Nikolay Petrov says "the snow in the outrun was too soft ... for the safety of the athletes we canceled the first jump."
The men's final in the Nordic combined normal hill is set for the same time Wednesday.
