The nor'easter caused widespread damage to New Jersey's coastline, including severe beach erosion and destruction of infrastructure such as boardwalks, railings, and ramps. Shore towns like Brigantine, Ocean City, and Sea Isle City were particularly affected, with significant portions of their beaches washed away. The damage poses risks to local communities, including potential flooding and further erosion during upcoming winter storms. The state is working to address these challenges promptly to protect residents and infrastructure.
