More than 4 million people across five states were under winter storm alerts on Sunday as heavy lake-effect snow continued to bury the Great Lakes region, prompting emergency declarations and the deployment of National Guard troops to rescue stranded motorists.

Acting Mayor Chris Scanlon held a news conference on Saturday to share the city's efforts during the winter storm.

The lake-effect snowstorm has disrupted holiday travel across the region. Some areas could get up to six feet of snow by Tuesday.
