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: Forecasts are not available for the Ingram Thorofare at Avalon (IN MLLW). Only observed stages are available for this point.

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

9.68 (Mean Lower Low Water (MLLW)) The level reached on October 29, 2012 during Post Tropical Cyclone Sandy.
8.96 (MLLW) The level reached on January 23, 2016.
8 (MLLW) MAJOR FLOODING. At this level, flooding starts to become severe enough to begin causing structural damage along with widespread flooding of roadways in Avalon. Vulnerable homes and businesses may be severly 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.
7 (MLLW) MODERATE FLOODING. At this level, widespread flooding of roadways begins due to high water and/or wave action with many roads becoming impassable in Avalon. 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.
6.6 (MLLW) Flooding begins in Avalon along Ocean Drive and Dune Drive.
6.3 (MLLW) COASTAL FLOOD ADVISORY LEVEL.
6 (MLLW) MINOR FLOODING.
