The nor'easter poses significant risks to coastal communities along the East Coast. Persistent onshore winds and high tides could lead to major flooding, especially in low-lying areas like the North Carolina Outer Banks and coastal Maryland. Beach erosion, dune washouts, and damage to coastal infrastructure are likely. Wind gusts of 60-70 mph could disrupt power and transportation, particularly in New England. Dangerous seas and rip currents will make ocean waters hazardous, while heavy rainfall may cause flash flooding in areas such as Boston, Rhode Island, and Cape Cod. Impacts are expected to persist through Monday.
