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.

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

16 Expect major coastal flooding in the Cape Cod Bay area stretching from Sandwich eastward thru Brewster. This includes extensive flooding of low lying roads, including Route 6A. Buildings adjacent to Sandwich Harbor and some buildings around Town Neck Beach become flooded or surrounded by floodwaters. The Sandwich Boardwalk, Marina, and Harbormaster's Shack become flooded. Heed the advice of local officials, and evacuate if asked to do so.
15 Moderate to major coastal flooding is expected along portions of the Cape Cod Bay shoreline from Sandwich eastward thru Brewster, with some low lying homes and roadways becoming surrounded or inundated by floodwaters. Portions of Route 6A become flooded. Heed the advice of local officials, and evacuate if asked to do so.
14 Moderate coastal flooding is expected. Floodwaters will encroach and in some cases surround low lying homes along Cape Cod Bay in the greater vicinity of Sandwich, Brewster and Dennis. River Street in Sandwich becomes flooded and impassable. In Dennis and Brewester, a portion of Route 6A becomes flooded.
13 Minor coastal flooding occurs along lowest lying areas along the shoreline.
