More than 150 dead after Hurricane Helene dumps over 40tn gallons of rain

Searchers using helicopters to get past washed-out bridges and hike through wilderness to reach isolated homes

Hurricane Helene's death toll has surpassed 150 as searchers use helicopters to get past washed-out bridges and hike through wilderness to reach isolated homes.

Crews were still trudging through knee-deep muck and debris in the wake of the deadly category 4 storm that dumped more than 40tn gallons of rain on the southern US after it crashed ashore in Florida on Thursday.
