Web Portal Changes: In Spring 2024, the Advanced Hydrologic Prediction Service (AHPS) hosted at https://water.weather.gov will be replaced by the National Water Prediction Service (NWPS) at a repurposed https://water.noaa.gov. A preview of NWPS is available here, where you can see your station hydrograph by replacing SSSSS with the station 5-character id: https://preview.water.noaa.gov/gauges/SSSSS.

Flood Inundation Mapping: Experimental real-time flood Inundation mapping services for 10% of the United States are now available via the NWS Map Viewer. Additional products and geospatial services depicting River Forecast Center and National Water Model forecasts continue to be accessible as described in the StoryMap here.

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 Ludlum Thorofare at Sea Isle City (IN MLLW). Only observed stages are available for this point.

9.91 (Mean Lower Low Water (MLLW)) The level reached on October 29, 2012 during Post Tropical Cyclone Sandy.
8.79 (MLLW) The level reached on January 23, 2016.
8.49 (MLLW) The level reached during the northeaster on December 11, 1992.
7.85 (MLLW) The level reached on November 13, 2009.
7.7 (MLLW) MAJOR FLOODING. At this level, flooding starts to become severe enough to begin causing structural damage along with widespread flooding of roadways in Sea Isle City and Strathmere. Vulnerable homes and businesses may be severely 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.
6.7 (MLLW) MODERATE FLOODING. At this level, widespread flooding of roadways begins due to high water and/or wave action with many roads becoming impassable in Sea Isle City and Strathmere. 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.
6.5 (MLLW) Flooding begins on Central Avenue in Sea Isle City.
6.3 (MLLW) Flooding begins along Landis Avenue in Sea Isle City (around 29th Street). Flooding begins around the Townsends Inlet Bridge (Cape May County Route 619) between Sea Isle City and Avalon.
6.1 (MLLW) Flooding begins in Strathmere.
6 (MLLW) COASTAL FLOOD ADVISORY LEVEL.
5.7 (MLLW) MINOR FLOODING.
