I currently live in Seattle and snow is not common enough out here. It usually is a little dusting or an inch or two of snow once or twice in a year. When Seattle does get snow, the city tends to shut down or operate at low capacity, even more than cities that get far more inches of snow. The reason behind this is that Seattle, is filled with hills so the temperatures remain low and near freezing, so the snow melts but then freezes overnight, making roads slick, icy and dangerous. We get a maximum of 3-5 days of snow in the winter that settles on the ground.
