NOTE: Coastal flood impacts are dependent upon waves as well as tide level. High waves can result in flooding even if the tide level is below flood stage.

NOTE: During times when the area is under a Tropical Storm/Hurricane Watch or Warning, the storm tide or total water level forecast will reflect a plausible worst case scenario (versus the usual most likely scenario). Please refer here for additional storm surge information.

NOTE: Forecasts for the Atlantic Coast at Dennis Sesuit Harbor 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.
