Inundation Dashboard provides real-time and historical inundation information at select NOS stations. The product is available in three regions: New York City/Long Island Sound; Chesapeake Bay; and coastal North Carolina with additional regions to follow.

Latest water level observations, tide predictions and if available, model forecast water level relative to NWS flood thresholds for select NOS stations, along with next high tide information and forecast peak water level for today and tomorrow.
Photos depicting actual or estimated flooding along with corresponding water level observations from the nearest NOS tide station, relating measured water level with on-the-ground effects.
Latest forecast and intensity information for active tropical cyclones in the Atlantic and East Pacific.
Historic water level data relative to NWS flood thresholds (available under Inundation History).
Number of historical flood days per year based on exceedance of minor flood threshold (accessible under Inundation History).
