Hurricane Erin, once a formidable Category 5 storm, has now weakened to a Category 2 but continues to pose a significant threat to coastal areas. The New York City metropolitan area, including New Jersey beaches, is bracing for the impact of this powerful storm. From Tuesday through Thursday, dangerous rip currents and high surf are expected along the coastline, with waves potentially reaching up to 12 feet. Coastal flooding and erosion are also significant concerns as Erin approaches.
