A snowstorm is a storm that precipitation falls as snow. Snow is rain that has been frozen to a soft texture, and usually falls in the winter, unless you live in a tropical place, or a place with high temperatures all year.

Some effects in snowstorms are immobilizing a region and paralyze a city, stranding commuters, closing airports, stopping the flow of supplies, and disrupting emergency and medical services. The weight of snow can cause roofs to collapse and knock down trees and power lines.
