Vonn's World Cup season debut postponed by heavy snow in Austria
American ski star has spent 2 months recovering from knee injury
Lindsey Vonn's return to World Cup racing will have to wait another week.
Heavy snowfall has forced organizers to call off downhill and super-G races scheduled for the Austrian resort of St. Anton this weekend.
Vonn needs five more victories to break the overall World Cup record of 86 wins, set by Swedish great Ingemar Stenmark in the 1980s.
The International Ski Federation did not immediately announce where the St. Anton races could be made up at a later date.
Three metres (nine feet) of snow have already fallen in St. Anton, with another metre (three feet) expected in the coming days.
Crews removed 120,000 cubic metres of snow off the course but the continuing storm made it impossible to prepare for racing conditions.
