The decision was certainly a favourable one for Sadowski-Synnott, who had said she was not going to be able to compete in the women's final after suffering an injury in qualifying, which has now decided the winners, yesterday.

The 17-year-old became New Zealand's first-ever gold medallist at the event after scoring 91.75 points on the Pick'n'Shovel Slopestyle course in Park City.

It caps off an incredible 12 months in which she also won the bronze medal in the big air competition at the Pyeongchang 2018 Winter Olympic Games and the gold medal in slopestyle at last month's X Games in Aspen.

"I really liked the course - I thought it had a really nice flow," Sadowski-Synnott said.

"I love the options for the rails.

"They gave you a ton to experiment with and get creative with. 

"I was really stoked with yesterday's run.

"I dropped second from last, I put down my first run and was really, really happy.

"I got my rail line and then my jump suite which I hadn't been getting in practice."

Second place went to Norway's Silje Norendal with a score of 88.75 points, giving the 25-year-old her second World Championships podium in as many starts after she took bronze in the 2017 competition in Sierra Nevada in Spain.

Completing the top three was one of snowboarding's all-time greats in Jamie Anderson of the US as the two-time Olympic gold medallist took the bronze with a score of 87.25 points.

It gives her a first career World Championships medal in her one and only start.

On the men's side, Corning was awarded the gold medal with a score of 93.25 points.

The American was clean, precise and technical throughout his run, finishing it with a massive triple cork 1440 on the bottom jump.

"I can't argue with the decision, there were definitely safety concerns," Corning said.

"It sucks, but it is what it is.

"I was really happy with my run yesterday.

"It was hard to see and probably one of the scariest contest runs I've had to do in a long time.

"I was looking forward to today to ride.

"But I'll take it, because I planted my run yesterday pretty solid."

Second place went to Canada's Mark McMorris, finishing behind Corning by the barest of margins with a score of 93.00 points.

Rounding out the podium was 17-year-old Judd Henkes of the US with a score of 90.50 points.

It meant the hosts finished today with three podiums and ended the World Championships as the medal table leader with five gold, three silver and six bronze.

"While everyone involved in the Utah 2019 slopestyle competition, from athletes to organisers, were saddened to cancel what was intended to be the grand finale of the World Championships, some of the sting was taken out of the decision by the fact that Saturday's qualifiers saw the best riding of the week on the Park City course, with the best athletes of the day able to put down their best runs," an FIS statement reads.

"Though the finals had the potential to be a fitting ender in the right conditions, Sunday's weather completely ruled out a suitable and safe World Championships competition taking place, and in the end nearly all agreed the right decision was made in cancelling the competition."
