The city has a new smartphone app to help New Yorkers stay informed during emergencies.

The Nofity NYC app is free to download on iTunes and Google Play.

It provides detailed alerts on weather events, traffic and transit disruptions, parking rule changes, and public health hazards based on location.

The Notify NYC program has issued more than 9,000 alerts since its inception in 2007.
