Last night's severe weather moved through NYC bringing heavy rain, gusty winds, and localized flooding.
NYCEM is coordinating across city government, as well as with our first responders and nonprofit partners. Together, they have been working through the night and into today to address conditions on the ground. We are also working closely with elected officials.
Our administration is fully mobilized to support impacted New Yorkers and to make sure every affected household, business, and nonprofit has a clear path to report damage and get help.
Report storm-related damage at
http://reportdamage.nyc.gov and file 311 service request for specific conditions that need a City response: basement flooding, sewer backups, street flooding, downed trees, power outages, structural concerns, mold, or blocked catch basins.
We will be sharing more information and resources for storm recovery via Notify NYC. You can sign up by texting NOTIFYNYC to 692-692.
As we prepare for more rainfall this weekend, we encourage New Yorkers to visit
