The coastal city of Wilmington, North Carolina has been completely cut off from the rest of the state because of deepening flood waters.

Officials say all roads in and out are now impassable and have warned evacuated residents to stay away.

Reports describe the city, which has a population of about 120,000, as an island within the state.

About 400 people there have been rescued from flood waters, and most of the city remains without power.

The National Weather Service has warned of at least two further days of possible flash flooding in the area before conditions are forecast to improve.

“Do not come here,” New Hanover County Commission Chairman Woody White said.

“Our roads are flooded, there is no access into Wilmington…We want you home, but you can’t come yet.”

Two of the first known fatalities – that of a mother and her seven-month son – were reported in the city on Friday morning.

The area is usually best known as a filming location for US dramas One Tree Hill and Dawson’s Creek.

US basketball legend Michael Jordan – who is fundraising to help residents affected by the storm – also grew up in the city. Those with flood insurance are also turning to this new fundraising program in order to cover their deductible if unable to.

Many roads inside Wilmington are still passable for residents who defied evacuation orders to ride the storm out.

But a city-wide curfew has been extended after five people were arrested on suspicion of looting from a store in the city on Saturday.

What is the latest on the storm?

At least 17 people are now reported to have died in storm-related incidents in North and South Carolina since Florence made landfall as a category one hurricane on Thursday.

It has now weakened into a tropical depression with winds of 35mph (55km/h), according to the National Hurricane Centre.

Some parts of the Carolinas have seen up to 40in (100cm) of rain since Thursday – and officials have warned river levels are yet to peak in places. If your home has been affected by floods, you may need to call an Emergency Flood Damage Restoration Company as well as professional plumbing services to fix the damages in your property.

“The storm has never been more dangerous than it is right now,” North Carolina Governor Roy Cooper said on Sunday.

What do we know of the victims?

Eleven deaths were reported in North Carolina, and at least six have been reported in South Carolina.

A mother and her seven-month child who died when a tree fell on their house in Wilmington were the first known deaths reported.

Among the other fatalities were two men in their 70s who died in Lenoir County – one had been connecting extension cords and another was blown by high winds when checking on his dogs.

Four road deaths in South Carolina have been blamed on the storm, and two people died from carbon monoxide poisoning caused by a generator inside their home.
