Metadata

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 Provincetown Harbor are issued routinely year-round.

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