8 Along low lying portions of the Long Island Sound, two to three feet of inundation is possible a few blocks inland with one to two feet of inundation possible north of I-95 in several low spots around waterways such as the Niantic River in Niantic, the Mystic River in Mystic. Nearly fifteen miles inland along the Connecticut and Thames Rivers, inundation is also possible with major damage in regions such as West End Drive and Seaside Lane in Old Lyme.
6.5 Inundation of one to two feet of water occurs on streets and several properties in Saybrook Point, as well as in the Marina where several feet of water is possible, as water reaches over the seawall.
6 Coastal flooding causes Niantic River Road to close between 1st and 2nd Avenue.
5 Flooding occurs in the downtown Mystic area directly along the waterfront, primarily in the street on Gravel Street and River Road. Groton experiences minor shoreline flooding.
