The Olympic men’s snowboardcross has been pushed back to Tuesday because of fog.

Officials postponed the race early Monday afternoon after a heavy fog blanketing Rosa Khutor Extreme Park failed to lift.

The decision came after officials scrubbed the seeding runs originally set for 10 a.m. local time (1 a.m. ET). The expected 1:30 p.m. start of the elimination rounds came and went with visibility still low.

Tuesday’s race will be under a modified format. There will be no qualifying and instead the racers will be bracketed based on their world ranking.

There will be seven heats of five riders each and one heat of four. The top three in each will advance to the quarterfinal rounds. Nate Holland and Trevor Jacob of U.S. will ride in the same opening heat.

“I called it as soon as I got here, that there would be bad weather on the day I race,” Australian snowboardcross racer Jarryd Hughes said. “It can’t stay sunny the whole time for that long.”

The postponement is the second of the games. Officials pushed back the men’s 15-kilometre mass-start biathlon race from Sunday to Monday and then again from Monday to Tuesday because of fog.
