NOTE: Graphical forecasts are not available during times of high water, forecast crest information can be found in the local WFO web page.
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.
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.
National Water Model Hydrograph
Official NWS streamflow forecasts are produced by NWS hydrologic forecasters for river gauge locations using hydrologic models which are calibrated to that location. This process considers additional guidance and information, including local expertise and experience, to produce the best forecast possible. The NWM output provides supplemental guidance to NWS forecasters and should not be considered an official NWS river forecast.
Flood Impacts
- 9.91 - (Mean Lower Low Water (MLLW)) The level reached on October 30, 2012 during Post Tropical Cyclone Sandy.
- 9.61 - (MLLW) The level reached on October 29, 2021.
- 9.4 - (MLLW) MAJOR FLOODING. At this level, widespread roadway flooding begins near the Christina River and its tidal tributaries in Wilmington. 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 water becomes a danger to anyone who attempts to cross on foot or in a vehicle.
