Hurricane Helene: Scale of devastation from record storm unfathomable

One week ago Hurricane Helene made landfall on the south eastern part of the United States. In North Carolina, several mountain towns were hit with flash floods. More than 40 trillion gallons of rain drenched several states and if that much water had been concentrated over North Carolina, that would have covered the entire state in water one metre deep. Helene is the deadliest hurricane since Katrina. At least 220 people have died and as Jackson Proskow reports, the scale of damage remains difficult to fathom.
