Hurricane Helene: dozens dead as storm pummels south-eastern US

Residents in several states suffer power outages and heavy flooding as officials warn of very dangerous environment'

Helene left a dizzying path of destruction as it raged across the south-east United States on Friday, killing at least 40 people across four states, causing dangerous flooding and leaving millions without power.

The storm - which registered maximum sustained winds of 140mph - crashed ashore late on Thursday in north-western Florida as a potent category 4 hurricane. It weakened to a tropical storm and then to a depression as it moved across Georgia as well as the Carolinas on Friday afternoon, when residents whose communities experienced Helene's peak effects more directly were only just beginning to fathom the recovery process ahead.
