NOTE: Please refer to our Coastal Hazard Message for specific information regarding Coastal Flood Watches, Warnings and Advisories.  During tropical cyclones, please refer here for additional storm surge information.

NOTE: Flood impacts are based on long-term averages. Actual impacts from any tidal 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.

NOTE: Graphical forecasts are not available for the Rehoboth Bay at Dewey Beach. During times of high water, forecast crest information can be found in the text products.

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

7.34 (Mean Lower Low Water (MLLW)) The level reached on March 6, 1962.
5.68 (MLLW) The level reached on October 29, 2012 during Post Tropical Cyclone Sandy.
5.3 (MLLW) MAJOR FLOODING. At this level, flooding starts to become severe enough to begin causing structural damage along with widespread flooding of roadways near Rehoboth Bay and the tidal waterways that flow into it. Vulnerable homes and businesses may be severely damaged as water levels rise further above this threshold. Numerous roads become impassable and some neighborhoods may be isolated. The flood waters become a danger to anyone who attempts to cross on foot or in a vehicle.
4.3 (MLLW) MODERATE FLOODING. At this level, widespread flooding of roadways begins with many roads becoming impassable near Rehoboth Bay and the tidal waterways that flow into it. Lives may be at risk when people put themselves in harm's way. Some damage to vulnerable structures may begin to occur. COASTAL FLOOD WARNING LEVEL.
3.6 (MLLW) COASTAL FLOOD ADVISORY LEVEL.
3.5 (MLLW) Flooding begins at Old Landing on Rehoboth Bay. Flooding begins along sections of DE Route 1 between Dewey Beach and Indian River Inlet, including the Delaware Seashore State Park. Flooding begins in Dewey Beach.
3.3 (MLLW) MINOR FLOODING.
