Wider weather episode

The center of Hurricane Erin stayed several hundred miles east of the Middle Atlantic coast on August 21, 2025. However, due the extremely large size of the cyclone with an expansive wind field, tropical storm force gusts occurred over the coastal waters and lower/middle Chesapeake Bay. Large swell of up to 15 feet from Erin impacted the Middle Atlantic coastal waters causing significant beach erosion and rip currents.
