(CNN) -- Thousands of travelers spent the night camped out on airport floors and thousands more were stranded in hotel rooms and relatives' homes as blizzard conditions halted flights at New York's three major airports, slowed rail travel and continued to create treacherous conditions on roads throughout the East Coast on Monday.
The storm brought high winds -- in some cases as much as 80 miles per hour -- and blinding snow to much of the East Coast beginning Sunday. Some places were forecast to receive as much as 30 inches of snow overall. Blizzard warnings remained in effect through noon Monday for much of coastal New England, where coastal flooding was also a problem.
Incoming and departing flights were suspended at New York's John F. Kennedy and LaGuardia airports Sunday night, as well as at Newark Liberty International Airport in neighboring north New Jersey, Port Authority spokeswoman Sara Joren said.
The airports are now not expected to reopen until 4 p.m. ET Monday, according to the Federal Aviation Administration.
More than 2,500 flights have been cancelled since the storm began, according to airline representatives. CNN
