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 Dennis Sesuit Harbor (IN MLLW) are issued routinely year-round.

16 This is a serious and life threatening flood. Extensive flooding more than 3 feet deep occurs along the Cape Cod Bay shore from Sandwich through Dennis and Brewster. Low lying roads, including parts of Route 6A, are impassable. Buildings near Sandwich Harbor and some buildings around Town Neck Beach are flooded or surrounded by floodwaters. The Sandwich Boardwalk, Marina, and Harbormaster's Shack become flooded. Follow the instructions of local officials and evacuate if asked to do so.
15 Flooding 2 to 3 feet deep affects many low lying areas including shoreline roads along Cape Cod Bay from Sandwich through Dennis and Brewster. Some low lying homes and roadways becoming surrounded or inundated by deep floodwaters. Parts of Route 6A become impassable. Follow the instructions of local officials and evacuate if asked to do so.
14 Some shoreline roads are impassable including River Street in Sandwich and a part of Route 6A in Dennis and Brewster. Flooding 1 to 3 feet deep encroaches, and in some cases, surrounds low lying homes along Cape Cod Bay in Sandwich, Brewster, and Dennis.
13 Flooding up to one foot deep affects low lying sections along Cape Cod Bay. Somevulnerable coastal roads may impassable for a short time around high tide.
12 Shallow pockets of flooding less than one foot deep affect low lying areas along Cape Cod Bay. Some shoreline roads may be flooded for a short time around high tide from splashover from rough surf.
