Winter storm Juno is about to hit the Northeast, and it’s expected to slam coastal cities like NYC, Boston, and Philadelphia with up to (and possibly over) two feet of heavy snow. Blizzard conditions are expected in 7 states.

The National Weather Service is describing the upcoming storm as “life-threatening” and “historic”, with the peak impact expected to hit Monday night into Tuesday. Blizzard or near-blizzard conditions will make travel dangerous, and government officials throughout the Northeast are encouraging residents to stay at home.

The governors of both New York and New Jersey have declared a state of emergency, as the tri-state area prepares for more than 2 feet of snow, coastal flooding and heavy sustained winds that will make even the slightest travel hazardous.

“I want everyone to understand that we are facing — most likely — one of the largest snowstorms in the history of this city,” said New York City Mayor Bill de Blasio.

The current New York City snowfall record is 26.9 inches in February 2006.

To prepare for this major storm, over 5,000 flights have been canceled, schools and businesses are planning to close early, and cities are preparing to mobilize fleets of snowplows and salt spreaders. Boston’s Logan Airport said there would be no flights after 7 p.m. Monday, and the shutdown could last until late Wednesday.

Massachusetts Governor Charlie Baker warned residents to prepare for roads that are “very hard, if not impossible, to navigate,” power outages and potentially a lack of public transportation. Wind gusts of 75 mph or greater are possible for coastal areas of Massachusetts, forecasters said.

This major storm could instantly make up for what has been a largely snow-free winter in the Northeast.
