NOTE: Please refer to our Coastal Hazard Message for specific information regarding Coastal Flood Watches, Warnings and Advisories. Actual impacts from any coastal 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 (go to the web site and select the storm of interest) reflects a reasonable worst case scenario. The forecast above is the total water forecast that is most likely to occur.

NOTE: Forecasts for the Atlantic Coast at Gloucester (IN MLLW) are issued routinely year-round.

Flood Impacts & Photos Collapse

14 Widespread flooding of low lying coastal areas is expected from Marblehead through Gloucester northward to Salibury. Large surf and high tides will result in significant beach erosion. Evacuations of vulnerable coastal roads is likely along with numerous road closures. Significant structural damage to propery is possible. People in flood prone areas must take action now to protect life and property.
13 Significant flooding of low lying coastal locations is expected from Revere and Winthrop southward through Hull. Road closures and some evacuations of coastal sections is likely. Large swells and wave action will produce significant beach erosion.
12.5 Coastal flooding is expected along the North Shore from Marblehead northward along the coast to Newburyport. The combination of high tides and large swells will result in flooding of some immediate coastal roads and some road closures are anticipated.
12 Coastal flooding is expected along the north shore from Gloucester to Newburyport. Waves action will cause flooding on some coastal roads around the time of high tide.
11.5 Minor coastal flooding is expected along the North Shore from Gloucester to Newburyport. Waves action will likely cause some washover onto coastal roads around the time of high tide.
