According to this NYC Emergency Management Department press release issued yesterday:

New York City Emergency Management Department today launched a new public service announcement (PSA) that focuses on nuclear preparedness. While
the likelihood of a nuclear weapon
incident occurring in/near New York City is very low, it is important New
Yorkers know the steps to stay safe. The new PSA encourages New Yorkers to
take key, simple steps in the event of such an incident.

New York City Emergency Management has a multitude of free resources for
New Yorkers to prepare for emergencies, including no-notice events, said
New York City Emergency Management Commissioner Zach Iscol. As the
threat landscape continues to evolve, it is important that New Yorkers know
we are preparing for any imminent threats and are providing them with the
resources they need to stay safe and informed.

The PSA outlines three key steps New Yorkers should take:

  • Get inside.
  • Stay inside.
  • Stay tuned.

NYC Emergency Management works with several local, state, and federal
agencies to organize emergency response. In partnership with NYPD, FDNY, NYC
Department of Health & Mental Hygiene, MTA, and FEMA, the agency hosts
the
 PlanNowNYC website, which focuses on preparing for terrorist attacks and other no-notice
events, including nuclear events, as well as the steps to take if such an
event occurs.

The City also uses several forms of media to alert the public in an emergency, including Notify NYC, the City of New York’s free, official emergency communications program.
New Yorkers are encouraged to sign up for these free emergency alerts in
their preferred language and format by visiting the website at NYC.gov/notifynyc
or by calling 311.
