Sun Trust Park will host the fourth and final event of the World Cup, with the men's and women's finals taking place tomorrow evening under the spotlights. 

In the women's competition, Reira Iwabuchi of Japan looks likely to retain her title, sitting atop the Big Air rankings with 1900 points. 

The 18-year-old could still be caught by a few other riders, including team mate Miyabi Onitsuka, and Katie Ormerod of Britain, but would have to finish below sixth place for the first time in almost three years.

Two-time slopestyle Olympic gold medallist and PyeongChang 2018 big air silver medallist Jamie Anderson is expected to be representing the host nation. 

The home crowd will also be cheering on Chris Corning, who is on track to triumph in the men's World Cup competition. 

He leads the standings with 2,200 points, followed by Nic Lamframboise of Canada on 1,500 and Kalle Jarvilehto of Finland on 1,200. 

Following the conclusion of the Snowboard Big Air World Cup, the Freestyle Ski Big Air World Cup season will continue at the same venue on Sunday (December 21). 

Johanne Killi of Norway will be aiming to continue her good form, having topped the podium at the event in Beijing last week, moving into second in the World Cup standings. 

She is now on 150, just 10 points from Giulia Tanno of Switzerland. 

Another Swiss athlete, Mathilde Gremaud, is returning to competition after crashing in training in Beijing and is aiming to get her Big Air title defence back on track. 

In the men's competition, Birk Ruud of Norway is considered the favourite. 

He tops the standings with 180, followed by Teal Harle of Canada on 125 and home favourite Alexander Hall on 100.
