I wasn't quite sure where to post this so feel free to move it. There is a website where you can sign up and will get very quick notifications of all things related to emergencies in New York City. When I saw the "What's happening at LaGuardia" thread, I realized that if people belonged to the website they would know what's happening at the New York airports as well as other thngs.
It's really great to know immediately where there are fires, bridge delays, airport delays, etc. this is the link to the website https://a858-nycnotify.nyc.gov/notifynyc/
