The men's World Cup downhill and super-combi races scheduled for Dec. 9-10 were cancelled Wednesday because of a lack of snow and warm temperatures.
Organizers said they would soon decide on a possible replacement site for the races.
Two other World Cup events have already been cancelled due to warm weather. The season-opening races on the glacier in Soelden, Austria, in October were wiped out because of heavy rain, while the women's events set for St. Moritz, Switzerland, on Dec. 9-10 were cancelled due to lack of snow and warm temperatures.
The women also have races in Val d'Isere, but in the second week of December. Those, too, could be in jeopardy unless ski conditions improve.
Because of good snowfalls in North America, FIS officials are working with organizers in Aspen and Beaver Creek to stage some of the scrapped events in Colorado.
Races in Lake Louise, Alta., have not been affected. The men raced there last week and the women are competing this week.
A super-combi race combines the times of a single slalom run and shortened downhill run the same day.
