Web Portal Changes: The Advanced Hydrologic Prediction Service (AHPS) hosted at https://water.weather.gov will be replaced by the National Water Prediction Service (NWPS), with a target of Spring 2024. Existing AHPS content and features will be preserved and expanded within NWPS. The NWS is now accepting feedback on NWPS. Please visit https://www.weather.gov/owp/operations for more information.

Experimental National Water Center Products: Flood Inundation Mapping services are now available for 10% of the U.S. population. Please visit https://www.weather.gov/owp/operations for more information. The National Hydrologic Discussion, Area Hydrologic Discussion, Flood Hazard Outlook, and real-time geospatial services depicting River Forecast Center and National Water Model forecasts, continue to be accessible via the URL above, as described in the StoryMap here.



DID YOU KNOW... Please try our new TEST hydrograph page link at: https://preview.water.noaa.gov/gauges/abcde - Just replace “abcde” with your local hydrograph five character ID found in the lower left corner of the hydrograph.  In late March of 2024, the base URL path will become water.noaa.gov.  Feedback can be provided HERE

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

NOTE: During a Tropical Storm or Hurricane Watch or Warning, inundation mapping provided by the National Hurricane Center (go to the web site and select the storm of interest) reflects a reasonable worst case scenario. The forecast above is the total water forecast that is most likely to occur.

NOTE: Forecasts for the Atlantic Coast at Watch Hill Cove (IN MLLW) are issued routinely year-round.

Vertical Datum references a tidal datum (MLLW)...for more information see Tides and Currents .

12 Significant coastal flooding is likely. Road closures and localized evacuations are likely in parts of Westerly and Charlestown.
10 Flooding will affect coastal portions of Westerly and Charlestown. Localized road closures and evacuations may be necessary. Large wave action along the south coast will result in some beach erosion.
9 Minor flooding of coastal areas is expected across parts of Westerly and Charlestown. Heavy surf may also produce flooding on some immediate coastal roads nearest the time of high tide.
8 Minor flooding of coastal areas is expected across parts of Westerly and Charlestown. Heavy surf may also produce flooding on some immediate coastal roads nearest the time of high tide.
