Metadata

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 Narragansett Bay at Conimicut Light (IN MLLW) are issued routinely year-round.
