The nor'easter poses significant risks to coastal communities and travelers. Coastal flooding threatens properties and infrastructure in Virginia, North Carolina, Maryland, and Delaware, with the Outer Banks being particularly vulnerable. NC Highway 12 is expected to close, isolating residents and tourists in areas like Hatteras and Ocracoke. Major airports in the Northeast, including Boston Logan, JFK, and Newark, face elevated disruption risks due to wind shear, tidal flooding, and reduced ramp operations. Royal Caribbean's cruise ship diversions highlight the storm's impact on maritime travel, while airlines anticipate thousands of flight delays and cancellations. Travelers should prepare for extended disruptions and potential safety hazards.
