NOTE: Please refer to our Coastal Hazard Message for specific information regarding Coastal Flood Watches, Warnings and Advisories. 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. 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 reflects a plausible worst case scenario. The experimental forecast above is the total water forecast that is expected to occur.

NOTE: Forecasts for the Chesapeake Bay at Tolchester Beach (IN MLLW) are issued routinely year-round.

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

7.91 (Mean Lower Low Water (MLLW)) The level reached on September 19, 2003 during Hurricane Isabel.
5.5 (MLLW) MAJOR FLOODING. At this level, widespread roadway flooding begins near the bay and its tidal tributaries in Cecil County and Kent County. Vulnerable homes and businesses may be 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.
4.5 (MLLW) MODERATE FLOODING. At this level, additional roadways near the bay and its tidal tributaries in Cecil County and Kent County begin to flood. 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.
3.9 (MLLW) Flooding begins in Charlestown along the North East River. Flooding begins in Rock Hall, Skinners Neck, Piney Neck, McKinleyville and Cliffs City. Flooding begins along the Chester River in Chestertown and also south of Chestertown along Quaker Neck Road.
3.8 (MLLW) COASTAL FLOOD ADVISORY LEVEL.
3.5 (MLLW) MINOR FLOODING.
