The biathlon men's mass start was postponed on Sunday, and has been delayed until 3:30 p.m. local time today, weather permitting.
The entire men's snowboard cross event was postponed, and the qualification round was cancelled altogether.
Training for alpine skiing events has been difficult as well.
The fog has made for some eerie photos. Perfect location for a horror film.
