NOTE: Please refer to our Coastal Hazard Message for specific information regarding Coastal Flood Watches, Warnings and Advisories.  During tropical cyclones, please refer here for additional storm surge information.

NOTE: Flood impacts are based on long-term averages. Actual impacts from any tidal flooding event may vary due to factors such as rainfall, wave action, and the number of tide cycles during which there is an onshore flow.

NOTE: Forecasts are not available for the Delaware River at Newbold Island (IN MLLW). Only observed stages are available for this point.

13.22 (Mean Lower Low Water (MLLW)) The level reached on September 1, 2021 during Post Tropical Cyclone Ida.
12.62 (MLLW) The level reached on April 4, 2005.
12.5 (MLLW) The level reached on June 29, 2006 and on April 17, 2011.
12.26 (MLLW) The level reached on May 1, 2014.
12.24 (MLLW) The level reached on October 30, 2012 during Post Tropical Cyclone Sandy.
12.2 (MLLW) MAJOR FLOODING. At this level, widespread roadway flooding begins near the river and its tidal tributaries in Mercer County, Burlington County and lower Bucks County. Vulnerable homes and businesses may be damaged as water levels rise further above this threshold. Numerous roads become impassable and some neighborhoods may be isolated. The flood waters become a danger to anyone who attempts to cross on foot or in a vehicle.
11.2 (MLLW) MODERATE FLOODING. At this level, additional roadways near the river and its tidal tributaries in Mercer County, Burlington County and lower Bucks County begin to flood. Lives may be at risk when people put themselves in harm's way. Some damage to vulnerable structures may begin to occur. COASTAL FLOOD WARNING LEVEL.
11 (MLLW) Flooding begins near the Trenton public boat ramp. Flooding begins in the Duck Island section of Hamilton Township.
10.8 (MLLW) Flooding begins around Radcliffe Street and Mill Street in Bristol PA. Flooding begins along Tanner's Run near the intersection of US Route 130, Beverly Road and Devlin Avenue in Burlington Township NJ.
10.6 (MLLW) Flooding begins along the riverfront in Burlington City NJ.
