Hurricane Arthur weakens after causing floods

Hurricane Arthur has weakened to a Category 1 storm in the Atlantic after bringing flooding and power outages to North Carolina’s Outer Banks overnight.

The US National Hurricane Centre says Arthur’s maximum sustained winds have decreased to 90 mph (144 kph) with additional weakening expected.

The first named storm of the Atlantic hurricane season has upended plans along the East Coast for America’s Independence Day.

Meanwhile, a new tropical storm warning was issued for Nova Scotia in Canada, where Arthur is expected to head as it moves north east.
