New York, Feb 2 (IANS): As the US Midwest remains buried in snow, millions will wake up Monday to sleet and blizzard conditions on the East Coast -- the second round of winter weather pounding in a week.

The storm put more than nine million people in the Chicago area under a blizzard warning Sunday, CNN reported.

Flights were cancelled, schools closed and traffic snarled in the region. And as the blizzard moves east, metropolitan areas such as New York City and Boston will be coated in ice.

"We would expect a lot of icing on our roads and sidewalks -- up to a quarter inch of ice in some places, and a lot of that would happen in the early morning hours," New York City Mayor Bill de Blasio warned.

His Chicago counterpart echoed the same sentiment.

"In this 24-hour cycle, we're getting the same amount of snow we got in all of January," Mayor Rahm Emanuel said.

Chicago, which closed public schools Monday, could get as much as 15 inches of snow, the report added.

Boston, Detroit and Omaha joined the call to close public schools, with the latter cancelling after-school activities as well.

Boston will "get another round of wintery weather with new snow accumulations from 10 to 12 inches," the report added.
