A massive winter storm is impacting the eastern two-thirds of the United States, bringing heavy snow, ice, and frigid temperatures from New Mexico to New England.

Nearly a million people in the South, including Tennessee, Mississippi, Louisiana, and Texas, lost power as the storm hit.

States from Missouri to Maine are under winter storm warnings, with forecasters warning of dangerous ice on roads, bridges, and structures.

The storm has caused severe travel disruptions, with over 11,000 flight cancellations and 4,700 delays reported across the country, NPR has reported.

Officials urged residents to avoid travel unless necessary, while emergency services and media outlets are providing guidance on safety and storm preparedness.
