An unusually powerful March storm is trekking across the country with a wide range of hazards from strong winds that could set off blizzard conditions and dust storms to severe thunderstorms that could produce tornadoes.

Blizzard conditions in parts of southern Minnesota made travel there dangerous Wednesday morning, the weather service office in the Twin Cities warned on social media. Heavy snow and strong northerly winds slowed travel across much of the Twin Cities, southern Minnesota and western Wisconsin, the weather service said.

A mammoth and multifaceted storm is slamming the eastern half of the United States with powerful winds, blizzard conditions and severe thunderstorms for the second consecutive day.
