Australian mogul skier Dale Begg-Smith has missed a potential medal after a World Cup on the Vancouver 2010 Olympic site was cancelled due to bad weather.

Heavy fog enveloped the Cypress Mountain course - the venue for both freestyle skiing and snowboard events for the 2010 Games - after 40 of the 48 competitors in the men’s event had completed their qualifying run.

With judges unable to see the top jump on the course, the event went onto weather delay for more than four hours before being finally cancelled when attempts to get the final eight skiers down the hill failed.

Begg-Smith was sitting in second place at the time and, had the qualifying round been completed and a result declared, he could have picked up his third medal of the season.

In a double blow to the Australian team, rising young star Ramone Cooper also missed a top 16 result.

Cooper was sitting in 13th place with most of the eight skiers still to come ranked below him.

NSWIS scholarship athlete Robert Lovick was one of the eight skiers waiting for fog to lift for their run.

The AIS-OWI team now travels to Inawashiro, Japan, site of the 2009 World Championships.
