National Weather Service Advanced Hydrologic Prediction Service...
When the Pawtuxet River flooded in Rhode Island, I was watching this site to get a sense of how bad the flooding was and to put it in historic context (the National Weather Service has links to live data at many locations). This particular station in NYC at the Battery is important to keep an eye on with Hurricane Sandy because if the strom surge is over 10 feet, the subway system could flood and the issues confronting New York would be devastating. As meterologist Andy Lesage noted, "During Irene it got to 9.5ft, 8-12 inches shy of flooding the subway system so if the Battery gets to something like 10.25+ ft, it will indicate massive damage to the cities' infrastructure." For more see, the Weather Underground and Jeff Masters' analysis.
