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 Providence Fox Point (IN MLLW) are issued routinely year-round.

Flood Impacts & Photos

10	Flooding will be widespread across many Narragnasett Bay communities and evacuations are likely for the period of a few hours around high tide. Flooding will impact Mount Hope Bay as well. Coastal roads will become impassible and alternate routes for travel will be required.
9	Significant coastal flooding is expected across Narragansett Bay and Mount Hope Bay. Some local evactuations may be required and coastal roads will be flooded around the time of high tide. Marine interests should take necessary precautions to protect boats that are in port.
8	Flooding of low lying coastal areas can be expected over the West Bay from Wickford Cove north to areas in Providence that lie outside flood protection. Flooding will also impact portions of the Upper East Bay including Bristol, Barrington and communities along Mount Hope Bay northward through Somerset and Fall River. Some coastal roads will be impassible for a brief time nearest high tide.
7	Minor coastal flooding is expected in the lowest lying areas of Cranston and Warwick, from Sandy Point and Greenwich Bay northward. A few immediate coastal roads may briefly flood due to wave action.
