A powerful blizzard has struck New York City and a 250-mile stretch of the Northeast US.
New York City Mayor Bill de Blasio has declared that the storm, expected to hit late Monday afternoon and continue through the evening, could be historic.
At the New York region's three major airports:
•The FAA has issued a "ground stop" for operations at Newark Liberty International Airport. According to NYC Aviation, the ground stop prevents flights inbound to Newark from taking off from its point of origin. This affects inbound flights from as far west as Detroit, as far north as Maine, and as far south as Raleigh, North Carolina.
•LaGuardia Airport is also experiencing a ground stop due to poor visibility. According to NYC Aviation, there is a medium chance that the ground stop will be extended past 3:30PM. The FAA is also reporting in-flight delays of 16-30 minutes and increasing for inbound flights to LaGuardia.
•United Airlines announced earlier today that it will cancel all flights out of its hub at Newark Liberty International Airport.
•Despite worsening weather conditions Monday afternoon, JFK airport was operating with only limited delays.
Numerous flights were cancelled in advance of the storm.
According to NBC News, the New York State Thruway "and all other state controlled highways" will be shut down after midnight.
Connecticut will close its roads after 9 p.m.
Winter Storm Juno, a nor'easter moving up the East Coast, is what's causing everyone to prepare for the worst.
In total, almost 40 million people are expected to endure a blizzard that could dump 2 to 3 feet of snow across a band running from Washington, D.C., to New England.
The Metropolitan Transportation Authority reported that it was preparing for the blizzard but that as the morning commute began, trains and buses were operating normally. The MTA noted that service later in the day could be curtailed and that commuters should consider working from home, if possible.
In anticipation of several feet of snow, New York City has suspended alternate-side parking regulations, which means that drivers may have to spend some time later this week excavating their cars from snow drifts.
Garbage trucks will be off the streets as the city gears up its fleet of snowplows to kick into action once the heavy weather arrives.
The New York City public schools canceled all after-school activities and announced that the system would be closed on Tuesday.
