ALERT: December 5th update on the status of the nationwide data transmission error preventing stream gauge data collected at affected locations from being displayed on the Advanced Hydrologic Prediction Services (AHPS) webpages. As of 11/08/2018, The USGS has restored all impacted operational stream gauges to transmitting status. The status map of gauge outages from other agencies is here. The outage map will be updated each Thursday. We apologize for the service interruption and hope to have the data restored as soon as possible.

Flood Impacts & Photos Collapse
If you notice any errors in the below information, please contact our Webmaster
13.1 Inundation of one to three feet of water on the runways at LaGuardia Airport.
12.7 Inundation of one to two feet on taxiways at LaGuardia Airport and in Douglaston Park.
10.8 Inundation occurs on the FDR Drive in Manhattan. Elevated water levels on the East River force the water into catch basins and storm sewers and cause water to bubble and pour out of manholes on the northbound FDR Drive leading to road closures in the upper 80's and lower 90's. In Rye, inundation causes portions of Milton Road and Kirby Lane at the Tide Mill Basin to close.
10.2 Minor coastal flooding in Port Washington along Shore Road, Sector Drive, and Sunset Park on Main Street.
10 Milton Road and Kirby Lane in Rye close during high tide.
