Short answer

A winter storm is a storm whose main precipitation is snow, sleet or freezing rain. A blizzard is when strong wind blows the snow into whiteout conditions that make roads impassable. [S1][S2]

Key points

• Winter storms reach the whole United States; even Hawaii's Big Island gets snow, and cities as far south as Atlanta and Dallas have been shut down by snow and ice. [S2]
• Most of the danger is indirect, such as crashes on icy roads, rather than the storm itself. [S1][S2]
