Significant Coastal Flooding and Beach Erosion Anticipated Fri-Sun

A storm system moving into the Northeast tonight will develop into a powerful ocean storm just south of New England over the course of the day on Friday… and slowly spin east and southeast away from the region over the course of the weekend.

The storm’s slow movement, large size and very strong onshore winds, combined with high astronomical tides due to the full moon, will result in a substantial – likely major – coastal flooding event around the area with multiple high tide cycles impacted.

Beach erosion along the outer arm of the Cape from Chatham northward to Provincetown and inside of Cape Cod Bay – mainly from Sandwich to Brewster – will be significant and likely shoreline-altering in some locations. The combination of high water and large waves battering the shores over multiple tide cycles will bring significant impacts to beaches and dunes.

A Coastal Flood Watch is posted and will likely be converted to a warning today.
