The Olympics are underway in Italy, with venues scattered across a wide area of the Alps whether there is snow cover or not. The magic of artificial snow generation makes sure that what you see on TV appears perfect for skiing, snowboarding, and cross-country racing. In fact, many of the races at the Beijing Olympics in 2022 were run completely on machine-generated snow. Yet the lack of reliable snow over the past few deacdes affects the ability of athletes to train for the competitions in their home countries.
Any Olympic course that doesn't have adequate natural snow will be groomed with manmade snow, which is real snow made from real water, but it's not the same. Flakes of natural snow are varied due to temperature, humidity, and other factors. Manmade snow is more uniform, and tends to compact faster. This leaves the courses slicker and often more dangerous.
