KRASNAYA POLYANA, Russia — A thick fog settled over the Rosa Khutor Extreme Park Monday morning, prompting race officials to cancel the seeding runs in men’s snowboarding cross.

Visibility was limited throughout the Caucasus mountains outside of Sochi. Officials were hoping conditions would improve and the snowboard cross event could still take place Monday. Without qualifying races, snowboarders will be seeded based on their current world rankings.

Fog on Sunday night forced biathlon officials to postpone the men’s 15-kilometer mass-start race.
