Another trick that some resorts that have big competitions (world cup etc) early in the year now do is store snow at the end the year under some insulated plastic and/or saw dust. They can spread that to the slope and guarantee conditions for the big event. Obviously if it is really warm it will melt away in a few days after that but at least they can have their event. Maybe they could do the same for these important spots around lifts etc.
