Precipitation Precipitation In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and "precipitates". Thus, fog and mist are not precipitation but suspensions, because the water vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with
Centenary 1000 Mt St Bernard and Hotham Heights. The stage however was interrupted with a torrential downpours of rain hail and sleet and the race was suspended at Mt Buffalo, after covering around . The riders were accommodated at the Mt Buffalo Chalet as they were effectively marooned, with the road to Wangaratta under of water, the Alpine road over Mt St Bernard was impassable and of snow fell at Mt Hotham. Milliken suffered a puncture on Mt Buffalo and had to wait more than an hour for a spare wheel. It was reported that he was almost frozen and he abandoned
