As Winter Storm Stella prepared to blanket the Northeast with more than a foot of snow this week, education officials were getting ready, too, by canceling school. Districts and schools in New York, New Jersey and other states called off classes Tuesday in advance of the impending blizzard.

New York City's public school system was one of the first to announce it was shutting down for the snow. In addition to all schools closing, after-school programs, adult education programs and other extracurricular activities were canceled, according to the city's education department.

Everyone — not just parents and students — was being urged to avoid going out during the storm, which was set to be accompanied by gusts of up to 50 mph.

"New Yorkers should also prepare for snow and dangerous road conditions," PIX11 reported Mayor Bill de Blasio told reporters. "Besides the snow, it will be cold. We urge you to avoid unnecessary travel and help keep roads clear for sanitation crews and first responders."

Here's a list of school closings in the Northeast ahead of Winter Storm Stella:
