Fierce seas in US north-east as Ernesto regains hurricane strength over Atlantic

Forecasters warn of life-threatening surf and rip tides: It's going to be really dangerous out in the water today'

Tropical Storm Ernesto became a hurricane again on Sunday as it churned away from Bermuda and headed further out in the Atlantic, sending powerful swells toward the US east coast, generating rip currents associated with at least one death and prompting many rescues.

The US National Hurricane Center in Miami said Ernesto's maximum sustained winds were 75mph (120km/h), just barely category 1 strength.
