How this forecast works
FloodRoute combines NOAA tide predictions for the The Battery station with the elevation of every road segment in New York City. When the predicted water level rises above a road's lowest point, it's marked — amber for possible, orange for likely, red for severe. The NOAA The Battery gauge shows how far the water is actually running above or below the tide tables; that difference is carried into the forecast and fades over the following days. Recent rain raises the next 24 hours. After each high tide, streets stay marked a little longer, because water drains off the road more slowly than the tide falls.
Tide source: NOAA station 8518750 (The Battery). Updated 1:41 AM.
