(CNN)The first nor’easter of 2021 is taking shape, bringing up to two feet of snow to New York City and other parts of the mid-Atlantic and Northeast Monday, according to updated forecasts from the National Weather Service.

In advance of the storm, New Jersey’s governor, Phil Murphy, declared a state of emergency, closing all six Covid-19 vaccine mega-sites, state offices and New Jersey transit. The storm threat prompted similar closures to vaccine sites in New York City.
