Blizzard warnings have been issued for New York City, Boston and parts of seven additional states for a potential historic Northeast Snowstorm, according to The Weather Channel.

Winter Storm Juno is scheduled to sweep through the Northeast Monday through Tuesday night. Parts of the region will see blizzard conditions, and more than two feet of snow as the storm will linger into Wednesday morning.

Blizzard warnings have been issued well in advance from parts of New Jersey all the way to Downeast Maine including Boston, Providence, Hartford and Portland.

The major storm is in effect for as early as 1 p.m. on Monday. Nearly 28 million people could be affected by the blizzards, while an additional 11 million are under winter storm warnings.

The Weather Channel urges people to prepare for harsh weather conditions by making sure they have proper supplies. It could be dangerous to travel late Monday and Tuesday as well.

Airlines have canceled over 2,000 flights for Monday by 7:30 a.m. as the major storm approaches, ABC News reported.

An additional 1,904 flights have been canceled for Tuesday, and the number is expected to rise.

New York City Mayor de Blasio told residents not to underestimate the winter storm.

"Prepare for something worse than we have seen before. Prepare to be safe. Take every precaution," he said in a press conference Sunday. "Now is the time to get ready for this extreme weather."

The mayor said this could be "one of the top two or three largest storms in the history of this city."

As storms approach the Northeast, the Massachusetts Emergency Management Agency is preparing for the storm.

"All of the things that come into play during these events, we want to make sure there are no surprises and everybody is on the same page," MEMA spokesman Peter Judge said.

New York City and Boston are expected to be hit the hardest.
