Tropical Storm Ophelia was downgraded to a post-tropical low on Saturday night but continued to pose a threat of coastal flooding and flash floods in the mid-Atlantic region, the US National Hurricane Centre has said.

Residents in parts of coastal North Carolina and Virginia experienced flooding on Saturday after the storm made landfall near a North Carolina barrier island, bringing rain, damaging winds and dangerous surges.
