Winter storm.

A winter storm is a meteorological event that occurs at colder temperatures and produces frozen precipitation. This precipitation may fall as snow, sleet, freezing rain, or a combination of the three. Winter storms can form only under specific meteorological conditions that require moist air, cold air, and lift in the atmosphere. Despite its name, a winter storm can develop in other seasons as long as the precipitation it produces is frozen. The United States has been hit with a number of devastating winter storms in its history. The most severe events dropped crippling amounts of snow and ice on parts of the country and resulted in numerous deaths and billions of dollars in damages.
