The nor'easter is expected to cause significant impacts along the Massachusetts coastline, including wind gusts of 50-65 mph in areas like Cape Ann, Cape Cod, and the Islands. Coastal flooding is anticipated, with 1-2 feet of water inundation and road closures near the shoreline. Inland areas west of I-95 will experience less severe conditions, with wind gusts of 30-40 mph and lighter rainfall. Power outages are possible in coastal regions during the peak winds late Friday through Saturday. Localized street flooding may occur due to heavy rain, but major river flooding is not expected.
