Carolinas

The National Hurricane Center predicts it will hit between north-eastern South Carolina and southern North Carolina sometime on Monday night.

Isaias was downgraded to a tropical storm after hitting islands in the Caribbean, where it caused the death of two people.

But it has now gathered strength with wind speeds of 75mph (120km/h).

It has caused catastrophic flooding since arriving as a category one hurricane on Friday.

Some towns have already seen 2ft (60cm) of rain in two days, with totals forecast to top 3.5ft (1m) in places.

It is feared that more communities could become deluged as the storm crawls west at only 2mph (3km/h).

"This system is unloading epic amounts of rainfall, in some places measured in feet and not inches," North Carolina Governor Roy Cooper said on Saturday.

It has been downgraded from a hurricane to a tropical storm but continues to soak the East Coast area with rain, downing trees and damaging homes.

It is slowly grinding over the eastern states, with winds of 65mph (105km/h).

Five deaths have been linked to the storm and thousands of people have been staying in emergency shelters.

Evacuation warnings were issued for 1.7 million people in the region.
